Christian mysticism is the tradition of mystical practices and mystical theology within Christianity which "concerns the preparation [of the person] for, the consciousness of, and the effect of [...] a direct and transformative presence of God" or Divine love. Until the sixth century the practice of what is now called mysticism was referred to by the term contemplatio, c.q. theoria, from contemplatio (Latin; Greek θεωρία, theoria), "looking at", "gazing at", "being aware of" God or the Divine. Christianity took up the use of both the Greek (theoria) and Latin (contemplatio, contemplation) terminology to describe various forms of prayer and the process of coming to know God.
Contemplative practices range from simple prayerful meditation of Holy Scripture (i.e. Lectio Divina) to contemplation on the presence of God, resulting in theosis (spiritual union with God) and ecstatic visions of the soul's mystical union with God. Three stages are discerned in contemplative practice, namely catharsis (purification), contemplation proper, and the vision of God.
The Greek theoria (θεωρία) meant "contemplation, speculation, a looking at, things looked at", from theorein (θεωρεῖν) "to consider, speculate, look at", from theoros (θεωρός) "spectator", from thea (θέα) "a view" + horan (ὁρᾶν) "to see". It expressed the state of being a spectator. Both Greek θεωρία and Latin contemplatio primarily meant looking at things, whether with the eyes or with the mind.
According to William Johnston, until the sixth century the practice of what is now called mysticism was referred to by the term contemplatio, c.q. theoria. According to Johnston, "[b]oth contemplation and mysticism speak of the eye of love which is looking at, gazing at, aware of divine realities."
"Mysticism" is derived from the Greek μύω, meaning "to conceal," and its derivative μυστικός, mystikos, meaning "an initiate." In the Hellenistic world, a "mystikos" was an initiate of a mystery religion. "Mystical" referred to secret religious rituals and use of the word lacked any direct references to the transcendental.
In early Christianity the term mystikos referred to three dimensions, which soon became intertwined, namely the biblical, the liturgical and the spiritual or contemplative. The biblical dimension refers to "hidden" or allegorical interpretations of Scriptures. The liturgical dimension refers to the liturgical mystery of the Eucharist, the presence of Christ at the Eucharist. The third dimension is the contemplative or experiential knowledge of God.
Definition of mysticism
Transformative presence of God
Bernard McGinn defines Christian mysticism as:
[T]hat part, or element, of Christian belief and practice that concerns the preparation for, the consciousness of, and the effect of [...] a direct and transformative presence of God.
McGinn argues that "presence" is more accurate than "union," since not all mystics spoke of union with God, and since many visions and miracles were not necessarily related to union.
Presence versus experience
McGinn also argues that we should speak of "consciousness" of God's presence, rather than of "experience", since mystical activity is not simply about the sensation of God as an external object, but more broadly about
...new ways of knowing and loving based on states of awareness in which God becomes present in our inner acts.
William James popularized the use of the term "religious experience" in his 1902 book The Varieties of Religious Experience. It has also influenced the understanding of mysticism as a distinctive experience which supplies knowledge.
Wayne Proudfoot traces the roots of the notion of religious experience further back to the German theologian Friedrich Schleiermacher (1768–1834), who argued that religion is based on a feeling of the infinite. The notion of religious experience was used by Schleiermacher to defend religion against the growing scientific and secular critique. It was adopted by many scholars of religion, of which William James was the most influential.
McGinn's emphasis on the transformation that occurs through mystical activity relates to this idea of "presence" instead of "experience":
This is why the only test that Christianity has known for determining the authenticity of a mystic and her or his message has been that of personal transformation, both on the mystic's part and—especially—on the part of those whom the mystic has affected.
Parsons points out that the stress on "experience" is accompanied by favoring the atomic individual, instead of the shared life on the community. It also fails to distinguish between episodic experience, and mysticism as a process that is embedded in a total religious matrix of liturgy, scripture, worship, virtues, theology, rituals and practices.
Richard King also points to disjunction between "mystical experience" and social justice:
The privatisation of mysticism – that is, the increasing tendency to locate the mystical in the psychological realm of personal experiences – serves to exclude it from political issues as social justice. Mysticism thus becomes seen as a personal matter of cultivating inner states of tranquility and equanimity, which, rather than seeking to transform the world, serve to accommodate the individual to the status quo through the alleviation of anxiety and stress.
Mystical experience is not simply a matter between the mystic and God, but is often shaped by cultural issues. For instance, Caroline Bynum has shown how, in the late Middle Ages, miracles attending the taking of the Eucharist were not simply symbolic of the Passion story, but served as vindication of the mystic's theological orthodoxy by proving that the mystic had not fallen prey to heretical ideas, such as the Cathar rejection of the material world as evil, contrary to orthodox teaching that God took on human flesh and remained sinless. Thus, the nature of mystical experience could be tailored to the particular cultural and theological issues of the time.
The idea of mystical realities has been widely held in Christianity since the second century AD, referring not simply to spiritual practices, but also to the belief that their rituals and even their scriptures have hidden ("mystical") meanings.
In subsequent centuries, especially as Christian apologetics began to use Greek philosophy to explain Christian ideas, Neoplatonism became an influence on Christian mystical thought and practice via such authors as Augustine of Hippo and Origen.
Jewish spirituality in the period before Jesus was highly corporate and public, based mostly on the worship services of the synagogues, which included the reading and interpretation of the Hebrew Scriptures and the recitation of prayers, and on the major festivals. Thus, private spirituality was strongly influenced by the liturgies and by the scriptures (e.g., the use of the Psalms for prayer), and individual prayers often recalled historical events just as much as they recalled their own immediate needs.
Of special importance are the following concepts:
- Binah (understanding), and Chokhmah (wisdom), which come from years of reading, praying and meditating the scriptures;
- Shekhinah, the presence of God in our daily lives, the superiority of that presence to earthly wealth, the pain and longing that come when God is absent; and the nurturing, feminine aspect of God;
- the hiddenness of God, which comes from our inability to survive the full revelation of God's glory and which forces us to seek to know God through faith and obedience;
- "Torah-mysticism", a view of God's laws as the central expression of God's will and therefore as worthy object not only of obedience but also of loving meditation and Torah study; and
- poverty, an ascetic value, based on the apocalyptic expectation of God's impending arrival, that characterized the Jewish people's reaction to being oppressed by a series of foreign empires.
The term theoria was used by the ancient Greeks to refer to the act of experiencing or observing, and then comprehending through nous.
The influences of Greek thought are apparent in the earliest Christian mystics and their writings. Plato (428–348 BC) is considered the most important of ancient philosophers, and his philosophical system provides the basis of most later mystical forms. Plotinus (c. 205 – 270 AD) provided the non-Christian, neo-Platonic basis for much Christian, Jewish and Islamic mysticism.
For Plato, what the contemplative (theoros) contemplates (theorei) are the Forms, the realities underlying the individual appearances, and one who contemplates these atemporal and aspatial realities is enriched with a perspective on ordinary things superior to that of ordinary people. Philip of Opus viewed theoria as contemplation of the stars, with practical effects in everyday life similar to those that Plato saw as following from contemplation of the Forms.
In the Enneads of Plotinus (c.204/5–270 CE), a founder of Neoplatonism, everything is contemplation (theoria) and everything is derived from contemplation. The first hypostasis, the One, is contemplation (by the nous, or second hypostasis)[failed verification] in that "it turns to itself in the simplest regard, implying no complexity or need"; this reflecting back on itself emanated (not created)[failed verification] the second hypostasis, Intellect (in Greek Νοῦς, Nous), Plotinus describes as "living contemplation", being "self-reflective and contemplative activity par excellence", and the third hypostatic level has theoria. Knowledge of The One is achieved through experience of its power, an experience that is contemplation (theoria) of the source of all things.
Plotinus agreed with Aristotle's systematic distinction between contemplation (theoria) and practice (praxis): dedication to the superior life of theoria requires abstention from practical, active life. Plotinus explained: "The point of action is contemplation. ... Contemplation is therefore the end of action" and "Such is the life of the divinity and of divine and blessed men: detachments from all things here below, scorn of all earthly pleasures, the flight of the lone to the Alone."
New Testamentical writings
The Christian scriptures, insofar as they are the founding narrative of the Christian church, provide many key stories and concepts that become important for Christian mystics in all later generations: practices such as the Eucharist, baptism and the Lord's Prayer all become activities that take on importance for both their ritual and symbolic values. Other scriptural narratives present scenes that become the focus of meditation: the Crucifixion of Jesus and his appearances after his Resurrection are two of the most central to Christian theology; but Jesus' conception, in which the Holy Spirit overshadows Mary, and his Transfiguration, in which he is briefly revealed in his heavenly glory, also become important images for meditation. Moreover, many of the Christian texts build on Jewish spiritual foundations, such as chokhmah, shekhinah.
But different writers present different images and ideas. The Synoptic Gospels (in spite of their many differences) introduce several important ideas, two of which are related to Greco-Judaic notions of knowledge/gnosis by virtue of being mental acts: purity of heart, in which we will to see in God's light; and repentance, which involves allowing God to judge and then transform us. Another key idea presented by the Synoptics is the desert, which is used as a metaphor for the place where we meet God in the poverty of our spirit.
The Gospel of John focuses on God's glory in his use of light imagery and in his presentation of the Cross as a moment of exaltation; he also sees the Cross as the example of agape love, a love which is not so much an emotion as a willingness to serve and care for others. But in stressing love, John shifts the goal of spiritual growth away from knowledge/gnosis, which he presents more in terms of Stoic ideas about the role of reason as being the underlying principle of the universe and as the spiritual principle within all people. Although John does not follow up on the Stoic notion that this principle makes union with the divine possible for humanity, it is an idea that later Christian writers develop. Later generations will also shift back and forth between whether to follow the Synoptics in stressing knowledge or John in stressing love.
In his letters, Paul also focuses on mental activities, but not in the same way as the Synoptics, which equate renewing the mind with repentance. Instead, Paul sees the renewal of our minds as happening as we contemplate what Jesus did on the Cross, which then opens us to grace and to the movement of the Holy Spirit into our hearts. Like John, Paul is less interested in knowledge, preferring to emphasize the hiddenness, the "mystery" of God's plan as revealed through Christ. But Paul's discussion of the Cross differs from John's in being less about how it reveals God's glory and more about how it becomes the stumbling block that turns our minds back to God. Paul also describes the Christian life as that of an athlete, demanding practice and training for the sake of the prize; later writers will see in this image a call to ascetical practices.
The texts attributed to the Apostolic Fathers, the earliest post-Biblical texts we have, share several key themes, particularly the call to unity in the face of internal divisions and perceptions of persecution, the reality of the charisms, especially prophecy, visions, and Christian gnosis, which is understood as "a gift of the Holy Spirit that enables us to know Christ" through meditating on the scriptures and on the Cross of Christ. (This understanding of gnosis is not the same as that developed by the Gnostics, who focused on esoteric knowledge that is available only to a few people but that allows them to free themselves from the evil world.) These authors also discuss the notion of the "two ways", that is, the way of life and the way of death; this idea has biblical roots, being found in both the Sermon on the Mount and the Torah. The two ways are then related to the notion of purity of heart, which is developed by contrasting it against the divided or duplicitous heart and by linking it to the need for asceticism, which keeps the heart whole/pure. Purity of heart was especially important given perceptions of martyrdom, which many writers discussed in theological terms, seeing it not as an evil but as an opportunity to truly die for the sake of God—the ultimate example of ascetic practice. Martyrdom could also be seen as symbolic in its connections with the Eucharist and with baptism.
Theoria enabled the Fathers to perceive depths of meaning in the biblical writings that escape a purely scientific or empirical approach to interpretation. The Antiochene Fathers, in particular, saw in every passage of Scripture a double meaning, both literal and spiritual.[note 1] As Frances Margaret Young notes, "Best translated in this context as a type of "insight", theoria was the act of perceiving in the wording and "story" of Scripture a moral and spiritual meaning," and may be regarded as a form of allegory.
The Alexandrian contribution to Christian mysticism centers on Origen (c. 185 – c. 253) and Clement of Alexandria (150–215 AD). Clement was an early Christian humanist who argued that reason is the most important aspect of human existence and that gnosis (not something we can attain by ourselves, but the gift of Christ) helps us find the spiritual realities that are hidden behind the natural world and within the scriptures. Given the importance of reason, Clement stresses apatheia as a reasonable ordering of our passions in order to live within God's love, which is seen as a form of truth. Origen, who had a lasting influence on Eastern Christian thought, further develops the idea that the spiritual realities can be found through allegorical readings of the scriptures (along the lines of Jewish aggadah tradition), but he focuses his attention on the Cross and on the importance of imitating Christ through the Cross, especially through spiritual combat and asceticism. Origen stresses the importance of combining intellect and virtue (theoria and praxis) in our spiritual exercises, drawing on the image of Moses and Aaron leading the Israelites through the wilderness, and he describes our union with God as the marriage of our souls with Christ the Logos, using the wedding imagery from the Song of Songs. Alexandrian mysticism developed alongside Hermeticism and Neoplatonism and therefore share some of the same ideas, images, etc. in spite of their differences.
Philo of Alexandria (20 BCE – c. 50 CE) was a Jewish Hellenistic philosopher who was important for connecting the Hebrew Scriptures to Greek thought, and thereby to Greek Christians, who struggled to understand their connection to Jewish history. In particular, Philo taught that allegorical interpretations of the Hebrew Scriptures provides access to the real meanings of the texts. Philo also taught the need to bring together the contemplative focus of the Stoics and Essenes with the active lives of virtue and community worship found in Platonism and the Therapeutae. Using terms reminiscent of the Platonists, Philo described the intellectual component of faith as a sort of spiritual ecstasy in which our nous (mind) is suspended and God's Spirit takes its place. Philo's ideas influenced the Alexandrian Christians, Clement, and Origen, and through them, Gregory of Nyssa.
Inspired by Christ's teaching and example, men and women withdrew to the deserts of Sketes where, either as solitary individuals or communities, they lived lives of austere simplicity oriented towards contemplative prayer. These communities formed the basis for what later would become known as Christian monasticism.
The Eastern church then saw the development of monasticism and the mystical contributions of Gregory of Nyssa, Evagrius Ponticus, and Pseudo-Dionysius. Monasticism, also known as anchoritism (meaning "to withdraw") was seen as an alternative to martyrdom, and was less about escaping the world than about fighting demons (who were thought to live in the desert) and about gaining liberation from our bodily passions in order to be open to the Word of God. Anchorites practiced continuous meditation on the scriptures as a means of climbing the ladder of perfection—a common religious image in the Mediterranean world and one found in Christianity through the story of Jacob's ladder—and sought to fend off the demon of acedia ("un-caring"), a boredom or apathy that prevents us from continuing on in our spiritual training. Anchorites could live in total solitude ("hermits", from the word erēmitēs, "of the desert") or in loose communities ("cenobites", meaning "common life").
Monasticism eventually made its way to the West and was established by the work of John Cassian and Benedict of Nursia. Meanwhile, Western spiritual writing was deeply influenced by the works of such men as Jerome and Augustine of Hippo.
Neo-Platonism has had a profound influence on Christian contemplative traditions. Neoplatonic ideas were adopted by Christianity,[note 2] among them the idea of theoria or contemplation, taken over by Gregory of Nyssa for example.[note 3] The Brill Dictionary of Gregory of Nyssa remarks that contemplation in Gregory is described as a "loving contemplation", and, according to Thomas Keating, the Greek Fathers of the Church, in taking over from the Neoplatonists the word theoria, attached to it the idea expressed by the Hebrew word da'ath, which, though usually translated as "knowledge", is a much stronger term, since it indicates the experiential knowledge that comes with love and that involves the whole person, not merely the mind. Among the Greek Fathers, Christian theoria was not contemplation of Platonic Ideas nor of the astronomical heavens of Pontic Heraclitus, but "studying the Scriptures", with an emphasis on the spiritual sense.
Later, contemplation came to be distinguished from intellectual life, leading to the identification of θεωρία or contemplatio with a form of prayer distinguished from discursive meditation in both East and West. Some make a further distinction, within contemplation, between contemplation acquired by human effort and infused contemplation.
In early Christianity the term "mystikos" referred to three dimensions, which soon became intertwined, namely the biblical, the liturgical and the spiritual or contemplative. The biblical dimension refers to "hidden" or allegorical interpretations of Scriptures. The liturgical dimension refers to the liturgical mystery of the Eucharist, the presence of Christ at the Eucharist. The third dimension is the contemplative or experiential knowledge of God.
The 9th century saw the development of mystical theology through the introduction of the works of sixth-century theologian Pseudo-Dionysius the Areopagite, such as On Mystical Theology. His discussion of the via negativa was especially influential.
Under the influence of Pseudo-Dionysius the Areopagite (late 5th to early 6th century) the mystical theology came to denote the investigation of the allegorical truth of the Bible, and "the spiritual awareness of the ineffable Absolute beyond the theology of divine names." Pseudo-Dionysius' apophatic theology, or "negative theology", exerted a great influence on medieval monastic religiosity. It was influenced by Neo-Platonism, and very influential in Eastern Orthodox Christian theology. In western Christianity it was a counter-current to the prevailing Cataphatic theology or "positive theology".
Cataphatic and apophatic mysticism
Within theistic mysticism two broad tendencies can be identified. One is a tendency to understand God by asserting what He is and the other by asserting what He is not. The former leads to what is called cataphatic theology and the latter to apophatic theology.
- Cataphatic (imaging God, imagination or words) – e.g., The Spiritual Exercises of St. Ignatius of Loyola, Julian of Norwich, Francis of Assisi; and
- Apophatic (imageless, stillness, and wordlessness) – inspired by the writings of Pseudo-Dionysius the Areopagite, which forms the basis of Eastern Orthodox mysticism and hesychasm, and became influential in western Catholic mysticism from the 12th century AD onward, as in The Cloud of Unknowing and Meister Eckhart.
Urban T. Holmes III categorized mystical theology in terms of whether it focuses on illuminating the mind, which Holmes refers to as speculative practice, or the heart/emotions, which he calls affective practice. Combining the speculative/affective scale with the apophatic/cataphatic scale allows for a range of categories:
- Rationalism = Cataphatic and speculative
- Pietism = Cataphatic and affective
- Encratism = Apophatic and speculative
- Quietism = Apophatic and affective
Meditation and contemplation
In discursive meditation, such as Lectio Divina, mind and imagination and other faculties are actively employed in an effort to understand our relationship with God. In contemplative prayer, this activity is curtailed, so that contemplation has been described as "a gaze of faith", "a silent love".[note 4] There is no clear-cut boundary between Christian meditation and Christian contemplation, and they sometimes overlap. Meditation serves as a foundation on which the contemplative life stands, the practice by which someone begins the state of contemplation.
John of the Cross described the difference between discursive meditation and contemplation by saying:
The difference between these two conditions of the soul is like the difference between working, and enjoyment of the fruit of our work; between receiving a gift, and profiting by it; between the toil of travelling and the rest of our journey's end".
Mattá al-Miskīn, an Oriental Orthodox monk has posited:
Meditation is an activity of one's spirit by reading or otherwise, while contemplation is a spontaneous activity of that spirit. In meditation, man's imaginative and thinking power exert some effort. Contemplation then follows to relieve man of all effort. Contemplation is the soul's inward vision and the heart's simple repose in God.
According to the standard formulation of the process of Christian perfection, going back to Evagrius Ponticus (345–399 AD) and Dionysius the Pseudo-Areopagite (late 5th to early 6th century), there are three stages:
- Katharsis or purification;
- Theoria or illumination, also called "natural" or "acquired contemplation;"
- Union or Theosis; also called "infused" or "higher contemplation"; indwelling in God; vision of God; deification; union with God
The three aspects later became purgative, illuminative, and unitive in the western churches and prayer of the lips, the mind, the heart in the eastern churches.
Purification and illumination of the noetic faculty are preparations for the vision of God. Without these preparations it is impossible for man's selfish love to be transformed into selfless love. This transformation takes place during the higher level of the stage of illumination called theoria, literally meaning vision, in this case vision by means of unceasing and uninterrupted memory of God. Those who remain selfish and self-centered with a hardened heart, closed to God's love, will not see the glory of God in this life. However, they will see God's glory eventually, but as an eternal and consuming fire and outer darkness.
In the Orthodox Churches, theosis results from leading a pure life, practicing restraint and adhering to the commandments, putting the love of God before all else. This metamorphosis (transfiguration) or transformation results from a deep love of God. Saint Isaac the Syrian says in his Ascetical Homilies that "Paradise is the love of God, in which the bliss of all the beatitudes is contained," and that "the tree of life is the love of God" (Homily 72). Theoria is thus achieved by the pure of heart who are no longer subject to the afflictions of the passions. It is a gift from the Holy Spirit to those who, through observance of the commandments of God and ascetic practices (see praxis, kenosis, Poustinia and schema), have achieved dispassion.[note 5]
Purification constitutes a turning away from all that is unclean and unwholesome. This is a purification of mind and body. As preparation for theoria, however, the concept of purification in this three-part scheme refers most importantly to the purification of consciousness (nous), the faculty of discernment and knowledge (wisdom), whose awakening is essential to coming out of the state of delusion that is characteristic of the worldly-minded. After the nous has been cleansed, the faculty of wisdom may then begin to operate more consistently. With a purified nous, clear vision and understanding become possible, making one fit for contemplative prayer.
In the Eastern Orthodox ascetic tradition called hesychasm, humility, as a saintly attribute, is called Holy Wisdom or sophia. Humility is the most critical component to humanity's salvation.[note 6] Following Christ's instruction to "go into your room or closet and shut the door and pray to your father who is in secret" (Matthew 6:6), the hesychast withdraws into solitude in order that he or she may enter into a deeper state of contemplative stillness. By means of this stillness, the mind is calmed, and the ability to see reality is enhanced. The practitioner seeks to attain what the apostle Paul called 'unceasing prayer'.
Some Eastern Orthodox theologians object to what they consider an overly speculative, rationalistic, and insufficiently experiential nature of Roman Catholic theology.[note 7] and confusion between different aspects of the Trinity.[note 8]
Theoria (illumination) – contemplative prayer
An exercise long used among Christians for acquiring contemplation, one that is "available to everyone, whether he be of the clergy or of any secular occupation", is that of focusing the mind by constant repetition of a phrase or word. Saint John Cassian recommended using the phrase "O God, make speed to save me: O Lord, make haste to help me". Another formula for repetition is the name of Jesus, or the Jesus Prayer: "Lord Jesus Christ, Son of God, have mercy on me, a sinner," which has been called "the mantra of the Orthodox Church", although the term "Jesus Prayer" is not found in the writings of the Fathers of the Church. The author of The Cloud of Unknowing recommended use of a monosyllabic word, such as "God" or "Love".
Contemplative prayer in the Eastern Church
In the Eastern Church, noetic prayer is the first stage of theoria,[note 9] the vision of God, which is beyond conceptual knowledge, like the difference between reading about the experience of another, and reading about one's own experience. Noetic prayer is the first stage of the Jesus Prayer, a short formulaic prayer: "Lord Jesus Christ, Son of God, have mercy on me, a sinner." The second stage of the Jesus Prayer is the Prayer of the Heart (Καρδιακή Προσευχή), in which the prayer is internalized into 'the heart'.
The Jesus Prayer, which, for the early Fathers, was just a training for repose, the later Byzantines developed into hesychasm, a spiritual practice of its own, attaching to it technical requirements and various stipulations that became a matter of serious theological controversy. Via the Jesus Prayer, the practice of the Hesychast is seen to cultivate nepsis, watchful attention. Sobriety contributes to this mental asceticism that rejects tempting thoughts; it puts a great emphasis on focus and attention. The practitioner of the Hesychast is to pay extreme attention to the consciousness of his inner world and to the words of the Jesus Prayer, not letting his mind wander in any way at all. The Jesus Prayer invokes an attitude of humility believed to be essential for the attainment of theoria. The Jesus Prayer is also invoked to pacify the passions, as well as the illusions that lead a person to actively express these passions. It is believed that the worldly, neurotic mind is habitually accustomed to seek pleasant sensations and to avoid unpleasant ones. This state of incessant agitation is attributed to the corruption of primordial knowledge and union with God (the Fall of Man and the defilement and corruption of consciousness, or nous).[note 10] According to St. Theophan the Recluse, though the Jesus Prayer has long been associated with the Prayer of the Heart, they are not synonymous.
Contemplative prayer in the Roman Catholic Church
Methods of prayer in the Roman Catholic Church include recitation of the Jesus Prayer, which "combines the Christological hymn of Philippians 2:6–11 with the cry of the publican (Luke 18:13) and the blind man begging for light (Mark 10:46–52). By it the heart is opened to human wretchedness and the Saviour's mercy"; invocation of the holy name of Jesus; recitation, as recommended by Saint John Cassian, of "O God, come to my assistance; O Lord, make haste to help me" or other verses of Scripture; repetition of a single monosyllabic word, as suggested by the Cloud of Unknowing, such as "God" or "Love"; the method used in Centering Prayer; the use of Lectio Divina. The Congregation for Divine Worship's directory of popular piety and the liturgy emphasizes the contemplative characteristic of the Holy Rosary and states that the Rosary is essentially a contemplative prayer which requires "tranquility of rhythm or even a mental lingering which encourages the faithful to meditate on the mysteries of the Lord's life." Pope John Paul II placed the Rosary at the very center of Christian spirituality and called it "among the finest and most praiseworthy traditions of Christian contemplation." In modern times, centering prayer, which is also called "Prayer of the heart" and "Prayer of Simplicity,"[note 11] has been popularized by Thomas Keating, drawing on Hesychasm and the Cloud of Unknowing.[note 12] The practice of contemplative prayer has also been encouraged by the formation of associations like The Julian Meetings and the Fellowship of Meditation.
The third phase, starting with infused or higher contemplation (or Mystical Contemplative Prayer) in the Western tradition, refers to the presence or consciousness of God. This presence or consciousness varies, but it is first and foremost always associated with a reuniting with Divine love, the underlying theme being that God, the perfect goodness, is known or experienced at least as much by the heart as by the intellect since, in the words 1 John 4:16: "God is love, and he who abides in love abides in God and God in him." Some approaches to classical mysticism would consider the first two phases as preparatory to the third, explicitly mystical experience, but others state that these three phases overlap and intertwine.
In the Orthodox Churches, the highest theoria, the highest consciousness that can be experienced by the whole person, is the vision of God.[note 13] God is beyond being; He is a hyper-being; God is beyond nothingness. Nothingness is a gulf between God and man. God is the origin of everything, including nothingness. This experience of God in hypostasis shows God's essence as incomprehensible, or uncreated. God is the origin, but has no origin; hence, he is apophatic and transcendent in essence or being, and cataphatic in foundational realities, immanence and energies. This ontic or ontological theoria is the observation of God.
A nous in a state of ecstasy or ekstasis, called the eighth day, is not internal or external to the world, outside of time and space; it experiences the infinite and limitless God.[note 5][note 14] Nous is the "eye of the soul" (Matthew 6:22–34).[note 15] Insight into being and becoming (called noesis) through the intuitive truth called faith, in God (action through faith and love for God), leads to truth through our contemplative faculties. This theory, or speculation, as action in faith and love for God, is then expressed famously as "Beauty shall Save the World". This expression comes from a mystical or gnosiological perspective, rather than a scientific, philosophical or cultural one.
- the first three are merely natural preliminary stages, corresponding to the vegetative, sensitive and rational levels of human life;
- the fourth stage is that of virtue or purification;
- the fifth is that of the tranquillity attained by control of the passions;
- the sixth is entrance into the divine light (the illuminative stage);
- the seventh is the indwelling or unitive stage that is truly mystical contemplation.
Teresa of Avila
According to Jordan Aumann, Teresa of Ávila distinguishes nine grades of prayer:
- vocal prayer,
- mental prayer or prayer of meditation,
- affective prayer,
- prayer of simplicity, or acquired contemplation or recollection,
- infused contemplation or recollection,
- prayer of quiet,
- prayer of union,
- prayer of conforming union, and
- prayer of transforming union.
According to Aumann, "The first four grades belong to the predominantly ascetical stage of spiritual life; the remaining five grades are infused prayer and belong to the mystical phase of spiritual life." According to Augustin Pulain, for Teresa of Avila ordinary prayer "comprises these four degrees: first, vocal prayer; second, meditation, also called methodical prayer, or prayer of reflection, in which may be included meditative reading; third, affective prayer; fourth, prayer of simplicity, or of simple gaze."
Prayer of simplicity – natural or acquired contemplation
For Teresa of Avila, in natural or acquired contemplation, also called the prayer of simplicity[note 11] there is one dominant thought or sentiment which recurs constantly and easily (although with little or no development) amid many other thoughts, beneficial or otherwise. The prayer of simplicity often has a tendency to simplify itself even in respect to its object, leading one to think chiefly of God and of his presence, but in a confused manner. Definitions similar to that of Saint Alphonsus Maria de Liguori are given by Adolphe Tanquerey ("a simple gaze on God and divine things proceeding from love and tending thereto") and Saint Francis de Sales ("a loving, simple and permanent attentiveness of the mind to divine things").
In the words of Saint Alphonsus Maria de Liguori, acquired contemplation "consists in seeing at a simple glance the truths which could previously be discovered only through prolonged discourse": reasoning is largely replaced by intuition and affections and resolutions, though not absent, are only slightly varied and expressed in a few words. Similarly, Saint Ignatius of Loyola, in his 30-day retreat or Spiritual Exercises beginning in the "second week" with its focus on the life of Jesus, describes less reflection and more simple contemplation on the events of Jesus' life. These contemplations consist mainly in a simple gaze and include an "application of the senses" to the events,: 121 to further one's empathy for Jesus' values, "to love him more and to follow him more closely.": 104
Natural or acquired contemplation has been compared to the attitude of a mother watching over the cradle of her child: she thinks lovingly of the child without reflection and amid interruptions. The Catechism of the Catholic Church states:
What is contemplative prayer? St. Teresa answers: 'Contemplative [sic][note 16] prayer [oración mental] in my opinion is nothing else than a close sharing between friends; it means taking time frequently to be alone with him who we know loves us.' Contemplative prayer seeks him 'whom my soul loves'. It is Jesus, and in him, the Father. We seek him, because to desire him is always the beginning of love, and we seek him in that pure faith which causes us to be born of him and to live in him. In this inner prayer we can still meditate, but our attention is fixed on the Lord himself.
Infused or higher contemplation
In the mystical experience of Teresa of Avila, infused or higher contemplation, also called intuitive, passive or extraordinary, is a supernatural gift by which a person's mind will become totally centered on God. It is a form of mystical union with God, a union characterized by the fact that it is God, and God only, who manifests himself. Under this influence of God, which assumes the free cooperation of the human will, the intellect receives special insights into things of the spirit, and the affections are extraordinarily animated with divine love. This union that it entails may be linked with manifestations of a created object, as, for example, visions of the humanity of Christ or an angel or revelations of a future event, etc. They include miraculous bodily phenomena sometimes observed in ecstatics.
In Teresa's mysticism, infused contemplation is described as a "divinely originated, general, non-conceptual, loving awareness of God." According to Dubay:
It is a wordless awareness and love that we of ourselves cannot initiate or prolong. The beginnings of this contemplation are brief and frequently interrupted by distractions. The reality is so unimposing that one who lacks instruction can fail to appreciate what exactly is taking place. Initial infused prayer is so ordinary and unspectacular in the early stages that many fail to recognize it for what it is. Yet with generous people, that is, with those who try to live the whole Gospel wholeheartedly and who engage in an earnest prayer life, it is common.
According to Thomas Dubay, infused contemplation is the normal, ordinary development of discursive prayer (mental prayer, meditative prayer), which it gradually replaces. Dubay considers infused contemplation as common only among "those who try to live the whole Gospel wholeheartedly and who engage in an earnest prayer life". Other writers view contemplative prayer in its infused supernatural form as far from common. John Baptist Scaramelli, reacting in the 17th century against quietism, taught that asceticism and mysticism are two distinct paths to perfection, the former being the normal, ordinary end of the Christian life, and the latter something extraordinary and very rare. Jordan Aumann considered that this idea of the two paths was "an innovation in spiritual theology and a departure from the traditional Catholic teaching". And Jacques Maritain proposed that one should not say that every mystic necessarily enjoys habitual infused contemplation in the mystical state, since the gifts of the Holy Spirit are not limited to intellectual operations.
According to Charles G. Herbermann, in the Catholic Encyclopedia (1908), saint Teresa of Avila described four degrees or stages of mystical union:
- incomplete mystical union, or the prayer of quiet or supernatural recollection, when the action of God is not strong enough to prevent distractions, and the imagination still retains a certain liberty;
- full or semi-ecstatic union, when the strength of the divine action keeps the person fully occupied but the senses continue to act, so that by making an effort, the person can cease from prayer;
- ecstatic union, or ecstasy, when communications with the external world are severed or nearly so, and one can no longer at will move from that state; and
- transforming or deifying union, or spiritual marriage (properly) of the soul with God.
The first three are weak, medium, and the energetic states of the same grace.
The Prayer of Quiet
For Teresa of Avila, the Prayer of Quiet is a state in which the soul experiences an extraordinary peace and rest, accompanied by delight or pleasure in contemplating God as present. The Prayer of Quiet is discussed in the writings of Teresa of Ávila, Francis de Sales, Thomas Merton and others.
Author and mystic Evelyn Underhill recognizes two additional phases to the mystical path. First comes the awakening, the stage in which one begins to have some consciousness of absolute or divine reality. Purgation and illumination are followed by a fourth stage which Underhill, borrowing the language of St. John of the Cross, calls the dark night of the soul. This stage, experienced by the few, is one of final and complete purification and is marked by confusion, helplessness, stagnation of the will, and a sense of the withdrawal of God's presence. This dark night of the soul is not, in Underhill's conception, the Divine Darkness of the pseudo-Dionysius and German Christian mysticism. It is the period of final "unselfing" and the surrender to the hidden purposes of the divine will. Her fifth and final stage is union with the object of love, the one Reality, God. Here the self has been permanently established on a transcendental level and liberated for a new purpose.
Eastern Orthodox Christianity
Eastern Christianity has preserved a mystical emphasis in its theology and retains in hesychasm a tradition of mystical prayer dating back to Christianity's beginnings. Hesychasm concerns a spiritual transformation of the egoic self, the following of a path designed to produce more fully realized human persons, "created in the Image and Likeness of God" and as such, living in harmonious communion with God, the Church, the rest of the world, and all creation, including oneself. The Eastern Christian tradition speaks of this transformation in terms of theosis or divinization, perhaps best summed up by an ancient aphorism usually attributed to Athanasius of Alexandria: "God became human so that man might become god."[note 17]
According to John Romanides, in the teachings of Eastern Orthodox Christianity the quintessential purpose and goal of the Christian life is to attain theosis or 'deification', understood as 'likeness to' or 'union with' God.[note 18] Theosis is expressed as "Being, union with God" and having a relationship or synergy between God and man.[note 19] God is the Kingdom of Heaven.
Theosis or unity with God is obtained by engaging in contemplative prayer, the first stage of theoria,[note 9] which results from the cultivation of watchfulness (Gk: nepsis). In theoria, one comes to see or "behold" God or "uncreated light," a grace which is "uncreated."[note 20][note 21] In the Eastern Christian traditions, theoria is the most critical component needed for a person to be considered a theologian; however it is not necessary for one's salvation. An experience of God is necessary to the spiritual and mental health of every created thing, including human beings. Knowledge of God is not intellectual, but existential. According to eastern theologian Andrew Louth, the purpose of theology as a science is to prepare for contemplation, rather than theology being the purpose of contemplation.
Theoria is the main aim of hesychasm, which has its roots in the contemplative practices taught by Evagrius Ponticus (345–399), John Climacus (6th–7th century), Maximus the Confessor (c. 580–662), and Symeon the New Theologian (949–1022). John Climacus, in his influential Ladder of Divine Ascent, describes several stages of contemplative or hesychast practice, culminating in agape. Symeon believed that direct experience gave monks the authority to preach and give absolution of sins, without the need for formal ordination. While Church authorities also taught from a speculative and philosophical perspective, Symeon taught from his own direct mystical experience, and met with strong resistance for his charismatic approach, and his support of individual direct experience of God's grace. According to John Romanides, this difference in teachings on the possibility to experience God or the uncreated light is at the very heart of many theological conflicts between Eastern Orthodox Christianity and Western Christianity, which is seen to culminate in the conflict over hesychasm.[note 22]
According to John Romanides, following Vladimir Lossky in his interpretation of St. Gregory Palamas, the teaching that God is transcendent (incomprehensible in ousia, essence or being), has led in the West to the (mis)understanding that God cannot be experienced in this life.[note 23] Romanides states that Western theology is more dependent upon logic and reason, culminating in scholasticism used to validate truth and the existence of God, than upon establishing a relationship with God (theosis and theoria).[note 24][note 25]
False spiritual knowledge
In the Orthodox Churches, theoria is regarded to lead to true spiritual knowledge, in contrast to the false or incomplete knowledge of rational thought, c.q. conjecture, speculation,[note 14] dianoia, stochastic and dialectics). After illumination or theoria, humanity is in union with God and can properly discern, or have holy wisdom. Hence theoria, the experience or vision of God, silences all humanity.
The most common false spiritual knowledge is derived not from an experience of God, but from reading another person's experience of God and subsequently arriving at one's own conclusions, believing those conclusions to be indistinguishable from the actual experienced knowledge.
False spiritual knowledge can also be iniquitous, generated from an evil rather than a holy source. The gift of the knowledge of good and evil is then required, which is given by God. Humanity, in its finite existence as created beings or creatures, can never, by its own accord, arrive at a sufficiently objective consciousness. Theosis is the gradual submission of a person to the good, who then with divine grace from the person's relationship or union with God, attains deification. Illumination restores humanity to that state of faith existent in God, called noesis, before humanity's consciousness and reality was changed by their fall.
In the orthodox Churches, false spiritual knowledge is regarded as leading to spiritual delusion (Russian prelest, Greek plani), which is the opposite of sobriety. Sobriety (called nepsis) means full consciousness and self-realization (enstasis), giving true spiritual knowledge (called true gnosis). Prelest or plani is the estrangement of the person to existence or objective reality, an alienation called amartía. This includes damaging or vilifying the nous, or simply having a non-functioning noetic and neptic faculty.[note 26]
Evil is, by definition, the act of turning humanity against its creator and existence. Misotheism, a hatred of God, is a catalyst that separates humanity from nature, or vilifies the realities of ontology, the spiritual world and the natural or material world. Reconciliation between God (the uncreated) and man is reached through submission in faith to God the eternal, i.e. transcendence rather than transgression[note 27] (magic).
The Trinity as Nous, Word and Spirit (hypostasis) is, ontologically, the basis of humanity's being or existence. The Trinity is the creator of humanity's being via each component of humanity's existence: origin as nous (ex nihilo), inner experience or spiritual experience, and physical experience, which is exemplified by Christ (logos or the uncreated prototype of the highest ideal) and his saints. The following of false knowledge is marked by the symptom of somnolence or "awake sleep" and, later, psychosis. Theoria is opposed to allegorical or symbolic interpretations of church traditions.
False asceticism or cults
In the Orthodox practice, once the stage of true discernment (diakrisis) is reached (called phronema), one is able to distinguish false gnosis from valid gnosis and has holy wisdom. The highest holy wisdom, Sophia, or Hagia Sophia, is cultivated by humility or meekness, akin to that personified by the Theotokos and all of the saints that came after her and Christ, collectively referred to as the ecclesia or church. This community of unbroken witnesses is the Orthodox Church.
But let him not remain in this condition. If he wishes to see Christ, then let him do what Zacchaeus did. Let him receive the Word in his home, after having previously climbed up into the sycamore tree, 'mortifying his limbs on the earth and raising up the body of humility'.— Metropolitan Hierotheos of Nafpaktos (1996), Life after Death
God is beyond knowledge and the fallen human mind, and, as such, can only be experienced in his hypostases through faith (noetically). False ascetism leads not to reconciliation with God and existence, but toward a false existence based on rebellion to existence.[note 27]
Latin Catholic mysticism
In the Latin Church terms derived from the Latin word contemplatio such as, in English, "contemplation" are generally used in languages largely derived from Latin, rather than the Greek term theoria. The equivalence of the Latin and Greek terms was noted by John Cassian, whose writings influenced the whole of Western monasticism, in his Conferences. However, Catholic writers do sometimes use the Greek term.
The Early Middle Ages in the West includes the work of Gregory the Great and Bede, as well as developments in Celtic Christianity and Anglo-Saxon Christianity, and comes to fulfillment in the work of Johannes Scotus Eriugena and the Carolingian Renaissance.
The High Middle Ages saw a flourishing of mystical practice and theorization corresponding to the flourishing of new monastic orders, with such figures as Guigo II, Hildegard of Bingen, Bernard of Clairvaux, the Victorines, all coming from different orders, as well as the first real flowering of popular piety among the laypeople.
The Late Middle Ages saw the clash between the Dominican and Franciscan schools of thought, which was also a conflict between two different mystical theologies: on the one hand that of Dominic de Guzmán and on the other that of Francis of Assisi, Anthony of Padua, Bonaventure, Jacopone da Todi, Angela of Foligno. Moreover, there was the growth of groups of mystics centered on geographic regions: the Beguines, such as Mechthild of Magdeburg and Hadewijch (among others); the Rhenish-Flemish mystics Meister Eckhart, Johannes Tauler, Henry Suso, and John of Ruysbroeck; and the English mystics Richard Rolle, Walter Hilton and Julian of Norwich. This period also saw such individuals as Catherine of Siena and Catherine of Genoa, the Devotio Moderna, and such books as the Theologia Germanica, The Cloud of Unknowing and The Imitation of Christ.
The Protestant Reformation downplayed mysticism, although it still produced a fair amount of spiritual literature. Even the most active reformers can be linked to Medieval mystical traditions. Martin Luther, for instance, was a monk who was influenced by the German Dominican mystical tradition of Eckhart and Tauler as well by the Dionysian-influenced Wesenmystik ("essence mysticism") tradition. He also published the Theologia Germanica, which he claimed was the most important book after the Bible and Augustine for teaching him about God, Christ, and humanity. Even John Calvin, who rejected many Medieval ascetic practices and who favored doctrinal knowledge of God over affective experience, has Medieval influences, namely, Jean Gerson and the Devotio Moderna, with its emphasis on piety as the method of spiritual growth in which the individual practices dependence on God by imitating Christ and the son-father relationship. Meanwhile, his notion that we can begin to enjoy our eternal salvation through our earthly successes leads in later generations to "a mysticism of consolation". Nevertheless, Protestantism was not devoid of mystics. Several leaders of the Radical Reformation had mystical leanings such as Caspar Schwenckfeld and Sebastian Franck. The Magisterial traditions also produced mystics, notably Peter Sterry (Calvinist), and Jakob Böhme (Lutheran).
As part of the Protestant Reformation, theologians turned away from the traditions developed in the Middle Ages and returned to what they consider to be biblical and early Christian practices. Accordingly, they were often skeptical of Catholic mystical practices, which seemed to them to downplay the role of grace in redemption and to support the idea that human works can play a role in salvation. Thus, Protestant theology developed a strong critical attitude, oftentimes even an animosity towards Christian mysticism. However, Quakers, Anglicans, Methodists, Episcopalians, Lutherans, Presbyterians, Local Churches, Pentecostals, Adventists, and Charismatics have in various ways remained open to the idea of mystical experiences.
The Spanish had Ignatius Loyola, whose Spiritual Exercises were designed to open people to a receptive mode of consciousness in which they can experience God through careful spiritual direction and through understanding how the mind connects to the will and how to weather the experiences of spiritual consolation and desolation; Teresa of Ávila, who used the metaphors of watering a garden and walking through the rooms of a castle to explain how meditation leads to union with God; and John of the Cross, who used a wide range of biblical and spiritual influences both to rewrite the traditional "three ways" of mysticism after the manner of bridal mysticism and to present the two "dark nights": the dark night of the senses and the dark night of the soul, during which the individual renounces everything that might become an obstacle between the soul and God and then experiences the pain of feeling separated from God, unable to carry on normal spiritual exercises, as it encounters the enormous gap between its human nature and God's divine wisdom and light and moves up the 10-step ladder of ascent towards God. Another prominent mystic was Miguel de Molinos, the chief apostle of the religious revival known as Quietism. No breath of suspicion arose against Molinos until 1681, when the Jesuit preacher Paolo Segneri, attacked his views, though without mentioning his name, in his Concordia tra la fatica e la quiete nell' orazione. The matter was referred to the Inquisition. A report got abroad that Molinos had been convicted of moral enormities, as well as of heretical doctrines; and it was seen that he was doomed. On September 3, 1687 he made public profession of his errors, and was sentenced to imprisonment for life. Contemporary Protestants saw in the fate of Molinos nothing more than a persecution by the Jesuits of a wise and enlightened man, who had dared to withstand the petty ceremonialism of the Italian piety of the day. Molinos died in prison in 1696 or 1697.
The English had a denominational mix, from Catholic Augustine Baker and Julian of Norwich (the first woman to write in English), to Anglicans William Law, John Donne, and Lancelot Andrewes, to Puritans Richard Baxter and John Bunyan (The Pilgrim's Progress), to the first "Quaker", George Fox and the first "Methodist", John Wesley, who was well-versed in the continental mystics.
An example of "scientific reason lit up by mysticism in the Church of England"is seen in the work of Sir Thomas Browne, a Norwich physician and scientist whose thought often meanders into mystical realms, as in his self-portrait, Religio Medici, and in the "mystical mathematics" of The Garden of Cyrus, whose full running title reads, Or, The Quincuncial Lozenge, or Network Plantations of the ancients, Naturally, Artificially, Mystically considered. Browne's highly original and dense symbolism frequently involves scientific, medical, or optical imagery to illustrate a religious or spiritual truth, often to striking effect, notably in Religio Medici, but also in his posthumous advisory Christian Morals.
Browne's latitudinarian Anglicanism, hermetic inclinations, and Montaigne-like self-analysis on the enigmas, idiosyncrasies, and devoutness of his own personality and soul, along with his observations upon the relationship between science and faith, are on display in Religio Medici. His spiritual testament and psychological self-portrait thematically structured upon the Christian virtues of Faith, Hope and Charity, also reveal him as "one of the immortal spirits waiting to introduce the reader to his own unique and intense experience of reality". Though his work is difficult and rarely read, he remains, paradoxically, one of England's perennial, yet first, "scientific" mystics.
Similarly, well-versed in the mystic tradition was the German Johann Arndt, who, along with the English Puritans, influenced such continental Pietists as Philipp Jakob Spener, Gottfried Arnold, Nicholas Ludwig von Zinzendorf of the Moravians, and the hymnodist Gerhard Tersteegen. Arndt, whose book True Christianity was popular among Protestants, Catholics and Anglicans alike, combined influences from Bernard of Clairvaux, John Tauler and the Devotio Moderna into a spirituality that focused its attention away from the theological squabbles of contemporary Lutheranism and onto the development of the new life in the heart and mind of the believer. Arndt influenced Spener, who formed a group known as the collegia pietatis ("college of piety") that stressed the role of spiritual direction among lay-people—a practice with a long tradition going back to Aelred of Rievaulx and known in Spener's own time from the work of Francis de Sales. Pietism as known through Spener's formation of it tended not just to reject the theological debates of the time, but to reject both intellectualism and organized religious practice in favor of a personalized, sentimentalized spirituality.
This sentimental, anti-intellectual form of pietism is seen in the thought and teaching of Zinzendorf, founder of the Moravians; but more intellectually rigorous forms of pietism are seen in the teachings of John Wesley, which were themselves influenced by Zinzendorf, and in the teachings of American preachers Jonathan Edwards, who restored to pietism Gerson's focus on obedience and borrowed from early church teachers Origen and Gregory of Nyssa the notion that humans yearn for God, and John Woolman, who combined a mystical view of the world with a deep concern for social issues; like Wesley, Woolman was influenced by Jakob Böhme, William Law and The Imitation of Christ. The combination of pietistic devotion and mystical experiences that are found in Woolman and Wesley are also found in their Dutch contemporary Tersteegen, who brings back the notion of the nous ("mind") as the site of God's interaction with our souls; through the work of the Spirit, our mind is able to intuitively recognize the immediate presence of God in our midst.
Fifteen Carmelite nuns allowed scientists to scan their brains with fMRI while they were meditating, in a state known as Unio Mystica or Theoria. The results showed that multiple regions of the brain that were activated when they considered themselves to be in mystical union with God. These regions included the right medial orbitofrontal cortex, right middle temporal cortex, right inferior and superior parietal lobules, caudate, left medial prefrontal cortex, left anterior cingulate cortex, left inferior parietal lobule, left insula, left caudate, left brainstem, and extra-striate visual cortex.
In modern times theoria is sometimes treated as distinct from the meaning given to it in Christianity, linking the word not with contemplation but with speculation. Boethius (c. 480–524 or 525) translated the Greek word theoria into Latin, not as contemplatio but as speculatio, and theoria is taken to mean speculative philosophy. A distinction is made, more radical than in ancient philosophy, between theoria and praxis, theory and practice.
Influential Christian mystics and texts

- In their biblical exegesis, whether of Alexandrian or Antiochene tradition, the Fathers, "with little or no understanding of the progressive nature of revelation, where the literal sense would not suffice, [...] resorted to allegory or to theoria (Chrysostom and the Antiochenes)."
- "From the point of view of the historian, the presence of Neoplatonic ideas in Christian thought is undeniable" 
- "The analogy between (Gregory's) terminology and thought and that of the ancient initiators of the philosophic ideal of life is a perfect one. The ascetics themselves are called by him 'philosophers' or 'the philosophic chorus'. Their activity is called 'contemplation' (θεωρία), and to the present day this word, even when we use it to designate the θεωρητικός βίος of the ancient Greek philosophers, has preserved the overtone which transformation into a technical term of Christian asceticism has added to it"
- "Contemplative prayer is the simple expression of the mystery of prayer. It is a gaze of faith fixed on Jesus, an attentiveness to the Word of God, a silent love. It achieves real union with the prayer of Christ to the extent that it makes us share in his mystery" (Catechism of the Catholic Church, 2724).
- Ecstasy comes when, in prayer, the nous abandons every connection with created things: first "with everything evil and bad, then with neutral things" (2, 3, 35; CWS p.65). Ecstasy is mainly withdrawal from the opinion of the world and the flesh. With sincere prayer the nous "abandons all created things" (2, 3, 35; CWS p.65). This ecstasy is higher than abstract theology, that is, than rational theology, and it belongs only to those who have attained dispassion. It is not yet union; the ecstasy which is unceasing prayer of the nous, in which one's nous has continuous remembrance of God and has no relation with the `world of sin', is not yet union with God. This union comes about when the Paraclete "...illuminates from on high the man who attains in prayer the stage which is superior to the highest natural possibilities and who is awaiting the promise of the Father, and by His revelation ravishes him to the contemplation of the light" (2, 3, 35; CWS p.65). Illumination by God is what shows His union with man. (Greek: ἀπάθεια, romanized: apatheia) and clarity of vision. Vision here refers to the vision of the nous that has been purified by ascetic practice.
- There was an anchorite (hermit) who was able to banish demons; and he asked them: Hermit: What make you go away? Is it fasting? The demons: We do not eat or drink. Hermit: Is it vigils? The demons: We do not sleep. Hermit: Is it separation from the world? The demons: We live in the deserts. Hermit: What power sends you away then? The demons: Nothing can overcome us, but only humility. Do you see how humility is victorious over the demons?
- A basic characteristic of the Frankish scholastic method, mislead by Augustinian Platonism and Thomistic Aristotelianism, had been its naive confidence in the objective existence of things rationally speculated about. By following Augustine, the Franks substituted the patristic concern for spiritual observation, (which they had found firmly established in Gaul when they first conquered the area) with a fascination for metaphysics. They did not suspect that such speculations had foundations neither in created nor in spiritual reality. No one would today accept as true what is not empirically observable, or at least verifiable by inference, from an attested effect. So it is with patristic theology. Dialectical speculation about God and the Incarnation as such are rejected. Only those things which can be tested by the experience of the grace of God in the heart are to be accepted. "Be not carried about by divers and strange teachings. For it is good that the heart be confirmed by grace," a passage from Hebrews 13.9, quoted by the Fathers to this effect.
- In the present case, Roman Catholic theologians are either confusing two dogmas — that is, the dogma of the personal existence of the Hypostases and the dogma of the Oneness of Essence, and it is absolutely essential to distinguish this from another dogma — or else they are confusing the inner relations of the All Holy Trinity with the providential actions and manifestations of the Father, the Son, and the Holy Spirit, which are directed towards the world and the human race. That the Holy Spirit is One in Essence with the Father and the Son, that therefore He is the Spirit of the Father and of the Son, is an indisputable Christian truth, for God is a Trinity One in Essence and Indivisible. [...] The expression, 'the Spirit of the Father and the Son", is likewise in itself quite Orthodox. But these expressions refer to the dogma of the Oneness of Essence, and it is absolutely essential to distinguish this from another dogma, the dogma of the begetting and the procession, in which, as the Holy Fathers express it, is shown the Cause of the existence of the Son and the Spirit. All of the Eastern Fathers acknowledge that the Father is monos aitios, the sole Cause” of the Son and the Spirit.
- Metropolitan Hierotheos Vlachos: "Noetic prayer is the first stage of theoria."
- The illness and cure of the soul in the Orthodox tradition, by Metropolitan Hierotheos of Nafpaktos: "If one wishes to be an Orthodox theologian one must begin from the state of Adam as it was before the Fall, what happened with the Fall and how we can be restored to our former state, even reach there where Adam did not. If a theology does not speak of man's fall; if it does not designate precisely what it is, and if it does not speak of man's resurrection, then what kind of theology is it? Surely, it is not Orthodox. In any case, we were saying earlier that Orthodoxy is a therapeutic treatment and science, and also that Theology is a therapeutic treatment. It cures man. Yet, if we do not examine where man's illness lies, how can we know what we should heal? If, regarding his body, man follows a wrong treatment he will never be cured. The same also happens with the soul. It must become clear to us that the darkness of nous is its illness and illumination is its cure. Mysteries and all the ascetic tradition of the Church are meant to lead us where Adam was before the Fall, that is, to the illumination of the nous, and from there to theosis, which is man's original destination. Therefore, it is very important for us to know exactly what the illness is. If we ignore our inner sickness our spiritual life ends up in an empty moralism, in a superficiality. Many people are against the social system. They blame society, family, the existing evil, etc. for their own problem. However the basic problem, man's real malady is the darkness of his nous. When one's nous is illumined one thus becomes free from slavery to everything in the environment, e.g. anxiety, insecurity, etc."
- catholicculture.org: "Meditation replaced by a purer, more intimate prayer consisting in a simple regard or loving thought on God, or on one of his attributes, or on some mystery of the Christian faith. Reasoning is put aside and the soul peacefully attends to the operations of the Spirit with sentiments of love."
- "Over the centuries, this prayer has been called by various names such as the Prayer of Faith, Prayer of the Heart, Prayer of Simplicity, Prayer of Simple Regard, Active Recollection, Active Quiet and Acquired Contemplation"
- That is to say, the man who beholds the uncreated light sees it because he is united with God. He sees it with his inner eyes, and also with his bodily eyes, which, however, have been altered by God's action. Consequently, theoria is union with God. And this union is knowledge of God. At this time one is granted knowledge of God, which is above human knowledge and above the senses.
- Vladimir Lossky: "It is necessary to renounce both sense and all the workings of reason, everything which may be known by the senses or the understanding, both that which is and all that is not, in order to be able to attain in perfect ignorance to union with Him who transcends all being and all knowledge. It is already evident that this is not simply a question of a process of dialectic but of something else: a purification, a katharis, is necessary. One must abandon all that is impure and even all that is pure. One must then scale the most sublime heights of sanctity leaving behind one all the divine luminaries, all the heavenly sounds and words. It is only thus that one may penetrate to the darkness wherein He who is beyond all created things makes His dwelling."
- "The eye is the lamp of the body. If your eye is healthy, your whole body will be full of light. But if your eye is unhealthy, your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness!" NRSV But what is the noetic function? In the Holy Scriptures there is, already, the distinction between the spirit of man (his nous) and the intellect (the logos or mind). The spirit of man in patristics is called nous to distinguish it from the Holy Spirit. The spirit, the nous, is the eye of the soul (see Matt. 6:226).
- Mental prayer, "oración mental," is not contemplative prayer.
- Literally, "God became man so that man might become god." Here, man is understood as human and no debate exists within the Church concerning a contrary interpretation.
- (Greek for "making divine", "deification", "to become gods by Grace", and for "divinization", "reconciliation, union with God." and "glorification") According to John Ramonides, theosis is "the selfless love of glorification (theosis) dedicated to the common good." — John Romanides
- Metropolitan Hierotheos Vlachos: "Theosis-Divinisation is the participation in the Uncreated grace of God. Theosis is identified and connected with the theoria (vision) of the Uncreated Light (see note above). It is called theosis in grace because it is attained through the energy, of the divine grace. It is a co-operation of God with man, since God is He Who operates and man is he who co-operates."
- Theophan the Recluse: "The contemplative mind sees God, in so far as this is possible for man."
- Metropolitan Hierotheos Vlachos: "This is what Saint Symeon the New Theologian teaches. In his poems, proclaims over and over that, while beholding the uncreated Light, the deified man acquires the Revelation of God the Trinity. Being in "theoria" (vision of God), the saints do not confuse the hypostatic attributes. The fact that the Latin tradition came to the point of confusing these hypostatic attributes and teaching that the Holy Spirit proceeds from the Son also, shows the non-existence of empirical theology for them. Latin tradition speaks also of created grace, a fact which suggests that there is no experience of the grace of God. For, when man obtains the experience of God, then he comes to understand well that this grace is uncreated. Without this experience there can be no genuine "therapeutic tradition.""

- www.monachos.net: "At the heart of Barlaam's teaching is the idea that God cannot truly be perceived by man; that God the Transcendent can never be wholly known by man, who is created and finite."
- Romanides: "And, indeed, the Franks believed that the prophets and apostles did not see God himself, except possibly with the exception of Moses and Paul. What the prophets and apostles allegedly did see and hear were phantasmic symbols of God, whose purpose was to pass on concepts about God to human reason. Whereas these symbols passed into and out of existence, the human nature of Christ is a permanent reality and the best conveyor of concepts about God.
- Romanides ideas have been very influential in the contemporary Greek Orthodox Churches, and are supported by man like Metropolitan Hierotheos (Vlachos) of Nafpaktos, Thomas Hopko, Professor George D. Metallinos[subnote 1] Nikolaos Loudovikos, Dumitru Stăniloae, Stanley S. Harakas and Archimandrite George, Abbot of the Holy Monastery of St. Gregorios of Mount Athos.
- Man has a malfunctioning or non-functioning noetic faculty in the heart, and it is the task especially of the clergy to apply the cure of unceasing memory of God, otherwise called unceasing prayer or illumination. "Those who have selfless love and are friends of God see God in light – divine light, while the selfish and impure see God the judge as fire – darkness".
- History of Russian Philosophy «История российской Философии »(1951) by N. O. Lossky. Section on N. O. Lossky's philosophy p. 262: "There is another kind of selfishness which violates the hierarchy of values much more: some agents who strive for perfection and the absolute fullness of being and even for the good of the whole world are determined to do it in their own way, so that they should occupy the first place and stand higher than all other beings and even the Lord God himself. Pride is the ruling passion of such beings. They enter into rivalry with God, thinking that they are capable of ordering the world better than its Creator. Pursuing an impossible aim, they suffer defeat at every step and begin to hate God. This is what Satan does. Selfishness separates us from God in so far as we put before us purposes incompatible with God's will that the world should be perfect. In the same way selfishness separates an agent in a greater or lesser degree from other agents: his aims and actions cannot be harmonized with the actions of other beings and often lead to hostility and mutual opposition.
- "We have a culture that creates saints, holy people. Our people's ideal is not to create wisemen. Nor was this the ideal of ancient Hellenic culture and civilization. Hellenic anthropocentric (human-centered) Humanism is transformed into Theanthropism (God-humanism) and its ideal is now the creation of Saints, Holy people who have reached the state of theosis (deification)."
