Early Developments

Written by: Beth Davies-Stofka

The earliest years of Christian historical development are shared by all the Christian traditions. The 3rd to 5th centuries witnessed the lively engagement of scholarly Christians with the new faith, and the growth and spread of monasticism. Both of these trends had significant influence on the beliefs and practices of Christianity. This article introduces the personalities that had the greatest impact on Eastern Orthodoxy, and outlines the influence of the monasteries on the eastern churches.

The first few centuries of the new faith were a very creative period of Christian writing and theological speculation. After Constantine's Edict of Milan brought to an end the official persecution of Christians, some of the best intellectual minds of the Roman Empire turned their talents to writing a dazzling number of volumes on questions of philosophy, theology, and the social and political implications of the new religion. This was the beginning of the age of the Church Fathers, also called the Patristic Age. Greek philosophical and theological writings, typical of the eastern Roman Empire, were distinctively speculative, asking questions about the nature of the Trinity, the Incarnation, and the meaning of the scriptures. Alongside the more speculative writings on philosophy and theology, the eastern Church Fathers also wrote volumes of poetry and mysticism.

Of the many Church Fathers, Eastern Christianity especially reveres Athanasius of Alexandria (c. 298-373), Basil of Caesarea (c. 329-379), his friend Gregory of Nazianzus (c. 329-391), Basil's younger brother Gregory of Nyssa (c. 335-c. 395), and John Chrysostom (c. 354-407). These priests and teachers are all venerated as saints, as are many of the other Church Fathers. John Chrysostom, Basil of Caesarea, and Gregory of Nazianzus are honored as the "three great hierarchs," or three great priests, and Eastern Orthodox Christianity celebrates a feast day for them on January 30. These Fathers of the Church are venerated for their multiple achievements, including their outstanding contributions to the development and dissemination of the doctrine of the Trinity.

Athanasius of Alexandria, also known as St. Athanasius the Great, was the Bishop of Alexandria (in modern-day Egypt). Along with his role in defining the New Testament canon, Athanasius was a strong defender of the concept of Christ's full divinity, and played a significant role in a doctrinal debate that started with Arius (c. 250-336), a priest from Alexandria. Arius maintained that Jesus was God's first creation, and therefore was not "coeternal" with God the Father, an idea known as Arianism. Many theologians and church leaders agreed with Arius, but others did not, and the Arian controversy seriously divided the church. Constantine convened the first ecumenical council at Nicaea in order to settle the antagonism over Arianism. Athanasius was the most influential opponent of Arianism, and contributed a critical term in the Nicene Creed, which professes that Christ is "of one substance" or "one in essence" with God the Father. In other words, Christ's divinity is in no way separate or distinct from God. In this way, Athanasius helped establish the essential monotheistic intent of the doctrine of the Trinity.
