The Spread of Christianity (300 CE – 600 CE)
Meet the theologians of the golden age of the Church Fathers. From the Council of Nicaea to the death of Gregory the Great, these giants of Christian thought defined orthodox doctrine and shaped the intellectual heritage of Catholic Christianity.
The Golden Age ofthe Church Fathers
The three centuries following Constantine produced the greatest concentration of theological genius in Christian history. The ecumenical councils of Nicaea, Constantinople, Ephesus, and Chalcedon defined the doctrines of the Trinity and the Incarnation, while individual theologians of towering intellect gave these definitions lasting expression.
In the East, St Athanasius stood contra mundum against Arianism; the Cappadocian Fathers - Basil, Gregory of Nazianzus, and Gregory of Nyssa - articulated Trinitarian theology; St John Chrysostom preached with golden eloquence. In the West, St Ambrose baptised St Augustine, whose writings would shape Christian thought for the next millennium. St Jerome translated the Scriptures into Latin, creating the Vulgate that served the Church for fifteen centuries.
These theologians wrote commentaries, homilies, letters, and treatises that remain foundational texts of Catholic theology. Their defence of orthodoxy against Arianism, Nestorianism, and Monophysitism established the Christological framework that the Church professes to this day.
