Mystical theology is a part of Christian theology that focuses on how God communicates with believers and the experiences people have when they encounter God. It explains practices like contemplative prayer, which is called theoria in Greek and means deep reflection or contemplation.
This area of study is different from other types of theology, such as systematic theology or dogmatic theology, which use statements or ideas to explain religious beliefs. Mystical theology is not about gaining knowledge but about having a personal experience of connecting with God.
Early Christianity
According to Origen (184/185–253/254 AD) and the Alexandrian theology, theoria refers to the knowledge of God in creation and the contemplation of sensible things. This knowledge and contemplation lead to a close relationship with God, similar to Divine Providence.
In the theological tradition of Macarius of Egypt (ca. 300–391 AD) and Pseudo-Macarius, theoria is the point where God and humans interact in the heart of a person, leading to the manifestation of spiritual gifts.
The highest form of contemplation comes from the heart, which is considered a higher form than intellectual contemplation. The idea that theoria is given to each person based on their ability to understand God is consistent across traditions. St. Symeon the New Theologian (949–1022 AD) taught that one cannot be a theologian unless they see the hypostases of God or the uncreated light. This experience fosters humility, meekness, and love for humanity, which are expressed as kindness and selfless love (agape) rooted in mortification, kenosis, or epiclesis. This agape, or holy fire, is central to Orthodox belief.
In the Cappadocian school of thought (Saint Basil, Saint Gregory of Nyssa, and Saint Gregory Nazianzus) (350–400 AD), theoria is the experience of the highest or absolute truth, achieved through complete union with God. This is described as entering the "Cloud of Unknowing," a state beyond rational understanding, embraced only through love of God (agape or awe). The Cappadocian fathers expanded beyond the intellectual contemplation of the Alexandrian tradition. This development began with the work Philokalia, which, through hesychasm, leads to phronema and finally theosis, validated by theoria. One must move beyond knowledge (gnosis) to faith (meta-gnosis). Through ignorance, one transcends knowledge and being, reaching theoria. In this tradition, theoria means understanding that the Uncreated cannot be grasped by the logical mind but only by the whole person (unity of heart and mind), a perception called nous. God is knowable through His manifestations, but ultimately, one must transcend knowledge, as gnosis is limited and can become a barrier between humans and God (as idolatry). To commune with God, one must enter the Divine filial relationship with God the Father through Jesus Christ, who shares the same essence (ousia) with the Father, resulting in pure faith without preconceived ideas of God. At this point, one can commune with God as Moses did. Gregory of Nyssa described the contemplation of the divine Being and its eternal Will as the culmination of the Christian religion.
Pseudo-Dionysius the Areopagite (5th to early 6th century; writing before 532 AD), influenced by the Neoplatonic philosopher Proclus, had a major impact on Christian thought and practice in both the East and West. Theoria is the central theme of Dionysius’ work The Mystical Theology. In chapter 1, Dionysius states that God dwells in divine darkness, meaning God is unknowable through sense and reason. Therefore, a person must leave behind the activity of sense and reason and enter spiritual union with God. Through this union (theosis), the mystic is granted theoria and ultimately gains knowledge of God. In Dionysius’ tradition, theoria is the lifting of the individual out of time, space, and created being, while the Triune God reaches down to the hesychast. This process is known as ekstasis ("mystical ecstasy").
While theoria is possible through prayer, it is most perfectly achieved through the Eucharist. The perfect vision of the deity, seen in its uncreated light, is called the "mystery of the eighth day." The eighth day represents the Eucharist and has an eschatological dimension, symbolizing a day beyond time. It marks the beginning of a new era in human history. Through the Eucharist, people experience
Eastern Orthodox Church
Symeon the New Theologian (also spelled "Simeon") (Greek: Συμεὼν ὁ Νέος Θεολόγος; 949–1022 AD) was a monk and poet from the Byzantine Empire. He was one of three saints recognized by the Eastern Orthodox Church with the title "Theologian," along with John the Apostle and Gregory of Nazianzus. The title "Theologian" did not mean he studied theology in the modern academic way. Instead, it meant he had personal experiences of seeing God. One of his main teachings was that humans can and should have theoria, which means direct experience of God through deep contemplation.
Symeon often wrote about seeing divine light in his writings. This experience was both inner and outer, and it began in his youth, continuing throughout his life. He described these moments as happening during prayer and contemplation, and they brought him great joy. He also said the light was a vision of God and that it showed him God’s grace. He taught that this experience required a mind that was completely calm and had gone beyond normal thoughts. At times, he wrote that the light spoke to him kindly and explained who it was.
A key idea in Symeon’s teachings was that all Christians should seek to have direct experiences of God through deep contemplation, or theoria. He believed these experiences were not unique to him but were possible for everyone. He taught that they came after prayer, repentance, and living a simple life. He especially encouraged monks to take on roles of spiritual leadership in the Church.
In his writings, Symeon emphasized the power of the Holy Spirit to change lives and the deep connection with God that comes from living a holy life. He called this the "Baptism of the Holy Spirit," which he compared to the more common "Baptism of water." He believed that Christianity had become too focused on rules and rituals, which had replaced the earlier emphasis on personal experiences of God. He argued that a true Christian life must include personal encounters with the living Christ, not just following rules.
Under St. Gregory Palamas (1296–1359 AD), different ideas about theoria were combined into a new understanding. Palamas taught that through baptism, people receive the Holy Spirit. By participating in church sacraments and practicing faith, people can build a relationship with God. If someone lives humbly and with devotion, like the Virgin Mary or the saints, and moves beyond rational thinking, they can experience God. Palamas said this was not a simple process because each person is different, but the way to experience God’s uncreated light is through contemplative prayer called hesychasm. Theoria is developed through the steps of theosis, which is the process of becoming more like God.
Gregory Palamas was asked by monks on Mount Athos to defend them against accusations from Barlaam of Calabria. Barlaam believed philosophers knew more about God than prophets and valued learning more than prayer. Palamas taught that the truth is Jesus Christ, a real person. He said that to be a true Christian, one must experience Christ as a real person. He also argued that when Peter, James, and John saw Jesus on Mount Tabor during the Transfiguration, they saw God’s uncreated light. He believed others could see this light through spiritual practices and prayer.
Palamas believed the only true way to experience Christ was through the Eastern Orthodox Church. Once someone finds Christ through the Church, they begin theosis, a process of becoming more like God. Theoria is the experience of God as a real person, not just as an idea. However, since God’s true nature is unknowable, people cannot fully understand it. Palamas said theoria is an experience of God that involves the whole person, not just the mind or body. This is different from knowledge gained through memory or time. He also said that all knowledge, including spiritual knowledge, is created, while theoria is the experience of God’s uncreated presence. The experience of God in the "eighth day" (a time beyond normal time) goes beyond personal knowledge. Palamas died on November 14, 1359, and his last words were, "To the heights! To the heights!" He is remembered on the Second Sunday of Great Lent because his work against Barlaam is seen as part of the Church’s victory over false teachings.
John Romanides (1927–2001) was an Orthodox priest, author, and professor. He had a major influence on modern Greek Orthodoxy, so some people talk about "pre- and post-Romanidian theology." Romanides believed that Eastern and Western Christianity became different because of the influence of the Franks, a culture very different from the Romans. He was part of a group of theologians in the 1960s who wanted to return to the teachings of early church leaders. This led to a stronger divide between East and West and a focus on opposing Western ideas.
Romanides’ writings focused on the experiential basis of theology, called theoria or seeing God directly, rather than understanding God through reason. He said this made Orthodox theology unique, especially compared to the Western Church, which he believed had lost the true spiritual path. He saw hesychasm as the core of Christian practice and studied the works of St. Gregory Palamas extensively.
Roman Catholic Church
According to Saint Gregory the Great, some people are able to see the "Eternal Brightness" of God while still living in their physical bodies. This happens through deep spiritual reflection, which allows them to grow in power and understanding.
Although the direct vision of God, known as the Beatific Vision, can only be experienced in the next life, God gives some people a special gift. This gift allows them to feel God's presence in their minds even before death. It lets them see God with great joy and be united with Him in a spiritual way while still alive. Saint Augustine said that in contemplation, people meet God face-to-face.
The goal of the Christian life is to see God in heaven. Augustine and others believe that the "contemplative life" is the final goal for all Christians. Contemplation on Earth is like a preview of heaven.
Contemplative prayer is not only for a few special people. It is meant for all baptized Christians. Jesus wants all His followers to experience this deep intimacy with God, which is the same kind of relationship He has with the Father.
The Catechism of the Catholic Church describes contemplation as a way of looking at Jesus with faith. A simple man once said, "I look at Him, and He looks at me." This kind of prayer helps people focus on Jesus rather than themselves. It purifies the heart and teaches people to see the world through Jesus' love and truth. Contemplation also helps people understand the mysteries of Jesus' life, which deepens their love for Him.
Contemplative prayer is a way of becoming more like God. It is a time when the Holy Trinity helps people grow to be more like God's image. This prayer also helps people grow in love and faith, as described in the Bible: "The Father strengthens our inner being with power through His Spirit so that Christ may dwell in our hearts through faith, and we may be grounded in love."
Saint John Cassian the Roman, who influenced Western monastic traditions, explained that Jesus taught in the story of Martha and Mary that the greatest good is found in divine contemplation. This kind of prayer begins by reflecting on holy people and grows into a deep understanding of God's beauty and knowledge.
Saint Augustine said that people can only find God in the deepest part of their own souls. He once wrote, "Too late loved I Thee, O Beauty so old, yet ever new! Too late loved I Thee. And behold, Thou wert within, and I abroad, and there I searched for Thee. Thou wert with me, but I was not with Thee." A hymn from the Byzantine Rite celebrates Augustine as "a wise hierarch who has received God."
Augustine is remembered not only as a contemplative but also as a theologian and a Church leader. A document from the Fifth Ecumenical Council, held in Constantinople in 553, said that Augustine's teachings on the true faith were followed completely. Another document from the same council called Augustine "of most religious memory, who shone forth resplendent among the African bishops."
Sometimes, contemplation can reach a level called religious ecstasy. Rarely, people might experience things like visions or stigmata during this time, but these are not essential to contemplation.
The writings of Saint Dionysius the Areopagite greatly influenced Western Christianity. These writings were used by many important theologians, including Peter Lombard, Alexander of Hales, Saint Albert the Great, Saint Thomas Aquinas, and Saint Bonaventure. According to Dionysius, mystical knowledge of God is different from the knowledge we gain through reason. Reason helps us understand God through the order of the universe, but mystical knowledge lets the soul see God's divine light directly.
Contemplation of God is more valuable than trying to understand God through logic or theology. It is not just a tool to improve knowledge but is the true perfection of theology. The experience of contemplatives is often beyond what words can describe, so they use metaphors and symbols to explain it.
According to Aquinas, some things about God can only be understood by thinking about what God is not, such as being unchanging, timeless, and simple. Pseudo-Dionysius taught that mystical knowledge does not try to understand what God is but instead senses it. Both Aquinas and Pseudo-Dionysius believed that some statements about God are similar to things humans can understand, such as being good, powerful, or loving.
