Basil of Caesarea (Basil the Great)
Cappadocian Father, defender of the deity of the Spirit, and architect of Eastern monasticism
Basil of Caesarea was archbishop of Caesarea and elder of the Cappadocian circle. In his landmark treatise *On the Holy Spirit* (De Spiritu Sancto), he defended the full equality and doxological glorification of the Holy Spirit with the Father and the Son, authored the Divine Liturgy of St. Basil, and established comprehensive monastic rules and the Basiliad charitable complex.

Gregory of Nazianzus is one of only three saints honored in Eastern Orthodoxy with the title 'The Theologian'. His *Five Theological Orations* delivered at the Church of the Anastasis in Constantinople established the doctrine of the eternal relations of origin (Father unbegotten, Son begotten, Holy Spirit proceeding), formulating the immortal Christological axiom: 'For that which He has not assumed He has not healed'.
Gregory of Nyssa, younger brother of Basil of Caesarea, was the most speculative and philosophical of the Cappadocians. In works such as *The Life of Moses*, *Great Catechism*, and *Against Eunomius*, he formulated the concept of *epektasis*—the soul's eternal, dynamic growth and progress into the infinite, inexhaustible life of God.
