Issue #5: The Cappadocian Fathers: The Integration of Theology and Spirituality

Previous Issue: Desert Spirituality: The Beginnings of Monasticism

In the previous blog, I mentioned that there was a more learned and liturgical monasticism in the heart of Cappadocia. While not all three Cappadocian Fathers were monks (only Basil the Great was a true monk), all of them were associated with and influenced by monastic spirituality and theology. Together, they made a meaningful contribution to Christian theology. Helleman and Gaiya provide us with a helpful overview of the Cappadocian Fathers:

Basil the Great, Bishop of Caesarea; Gregory of Nazianzus, Bishop of Constantinople; and Gregory of Nyssa, Bishop of Nyssa, were leading figures of the Cappadocian Church. Basil and Gregory of Nyssa were brothers, Gregory being the younger, and Basil and Gregory of Nazianzus were considered “best friends.” They had an excellent education in rhetoric and philosophy and were influenced by the writings of Origen. All three men were from prosperous families in Bithynia, in Asia Minor (present-day Turkey). At the time, Bithynia was the most Christian of the Roman territories. Together, the Cappadocian Fathers made significant theological contributions to the deity of Christ and the Holy Spirit, which were profoundly influential at the Council of Constantinople in AD 381. They affirmed the use of ousia to describe the “single divine essence of God.”[1]

Basil of Caesarea (AD 330–379)

During the persecution under the Roman Emperor Diocletian, Basil’s family had lost all their land, although most of it was recovered years later. Basil was sent to Athens to study, and there he became close friends with a fellow student, Gregory of Nazianzus,[2] whose father was also bishop of Nazianzus. Basil wanted to follow his father as a public orator and rhetorician. But after being persuaded by his sister, Macrina, some years later, he abandoned these aspirations and instead retreated to a corner of his parents’ estate and followed a monastic lifestyle and regula, or rule, together with some friends. Their monastic regime was studious, reading the works of Origen, especially his devotional writings. During this time, Basil developed an influential monastic rule for such communities.[3] 

Basil did not stay in this retreat for very long, because in AD 370 he was consecrated bishop of Caesarea in Cappadocia. He led Nicene Christianity in Asia Minor and pushed against the Arian factions, which involved him in no small amount of controversy. He was embroiled in several disputes and so was prompted to write on the Holy Spirit, which “appealed to liturgical and baptismal practice to cement the orthodox position on the Trinity.” He was a brilliant preacher and a gifted church leader and administrator.[4] Basil was a formidable theologian and churchman who left his brother, Gregory of Nyssa, in his shadow. Gregory truly came into his own after Basil died in AD 379 and proved to be a phenomenal theologian in his own right. The following prayer from Basil the Great provides us with a sense of his spirituality:

I know, Lord, that I partake unworthily of your pure body and precious blood, and that I am guilty, my Christ and my God, as I eat and drink condemnation to myself not discerning your body and blood. Yet, emboldened by your loving kindnesses, I come to you, who said, “he who eats my flesh and drinks my blood, abides in me and I in him.” Take pity, therefore, Lord, and do not rebuke me, a sinner, but deal with me mercifully. Let these holy gifts give me healing and cleansing, enlightenment and protection, salvation and sanctification of soul and body. May they avert every fantasy, evil practice, and operation of the devil enacted in my members by design. May they give me confidence in and love for you; amendment of life and perseverance, increase of virtue and perfection, fulfilment of your commandments, fellowship of the Holy Spirit, provisions for the journey of eternal life, and an acceptable answer at the awesome judgment seat. But let them not be for judgment or condemnation. Amen.[5]

Gregory of Nazianzus (AD 330–390)

Gregory, Basil’s closest friend, was an eloquent speaker and a powerful defender of the Nicene formula. Like his father, he became bishop of Nazianzus, but he also briefly served as bishop of Constantinople (AD 379–381). Although he disliked church politics and theological controversy, he was compelled to confront the heretical Arians, through which he became a brilliant promoter of Trinitarian orthodoxy. Gregory was an exceptional theologian—and he knew it.[6] Regrettably, his brilliance sometimes gave rise to a sense of vainglory.

Gregory of Nyssa (AD 335–395)

The youngest of the Cappadocian Fathers, Gregory of Nyssa, was the most prolific author of the three and influenced the conclusions at the Council of Constantinople by “reaffirming the Nicene Creed on the Son being ‘consubstantial’ (homoousios) with the Father.”[7] Of the three Fathers, Gregory of Nyssa was engaged most in philosophical reflection on the Trinity and employed Platonic terminology. And while his brother Basil and his friend Gregory wrote of virginity and asceticism, Gregory of Nyssa’s greatest work is The Life of Moses, along with his book The Life of Macrina, which was a memoir of his beloved sister who established female monastic communities similar to that of her brother Basil.[8]

It is Gregory’s The Life of Moses which forms the pinnacle of Cappadocian spirituality. Pope Benedict XVI writes that in this classical work, Gregory presents Moses “as a man journeying toward God: this climb to Mount Sinai became for him an image of our ascent in human life toward true life, toward the encounter with God.”[9] Dr. Carlos Eire, an expert on such mystical matters, explains in the Christian Mysticism Podcast on St. Gregory of Nyssa that Gregory of Nyssa’s interpretation of Moses’s life provides the reader with a guide to Christian mystical experience. He highlights three key moments in Moses’s journey that Gregory understood as important stages in this mystical quest. The first stage is “The Mountain of Divine Knowledge,” represented by Moses’s encounter with God in the burning bush on Mount Sinai, where “the contemplation of God transcends sensory perception and intellectual comprehension.” The second stage involves God appearing in a cloud, providing imagery of darkness as divine mystery, symbolizing the soul’s encounter with God, moving from light (knowledge of God through creation) to darkness (unknowing), where true mystical union occurs. The third stage refers to Moses receiving the tablets of the law and the construction of the Tabernacle, which serves as an image of the “Heavenly Tabernacle,” a spiritual reality “not made with hands.” It symbolizes union with God, mirroring the concept of a spiritual dwelling place.[10] Further, one might liken Moses’s journey to the threefold path of spiritual growth: Egypt and the Red Sea represent purification; Sinai and the Law, illumination; and the vision of God in the cloud, and union with him.

It should, however, be noted that Gregory’s The Life of Moses isn’t merely a biography; instead, it’s a profound allegorical and mystical interpretation of the life of Moses as a paradigm for the spiritual journey of the soul towards God. Oftentimes, his interpretations and allegories become quite fanciful; don’t expect the kind of biblical exposition one might find in the evangelical tradition. Always read the Cappadocian Fathers in the context in which they find themselves. Nevertheless, The Life of Moses is a central work in the Christian mystical tradition, which anticipates themes in both Eastern and Western mysticism that were to come later.

Task

Listen to the podcast on Gregory of Nyssa’s The Life of Moses, created by NotebookLM. You can find the recording of the podcast here. Write a short reflection on Gregory of Nyssa’s account of Moses’s ascent to Mount Sinai and his encounters with God. How does Gregory interpret the different stages of this ascent (e.g., the burning bush, the darkness and the cloud, the tabernacle), and what do these stages reveal about the nature of knowing and experiencing God?
