Gregory of Nazianzen, also known as Gregory the Theologian, was one of the leading theologians of the fourth-century Church. Together with Basil of Caesarea and Gregory of Nyssa, he is remembered as one of the Cappadocian Fathers and was instrumental in the development and defense of Nicene Trinitarian theology.
The orations collected here include Gregory’s celebrated Five Theological Orations, in which he addresses the divinity of the Son and the Holy Spirit and considers the proper language and method for speaking about the Trinity. Other orations address theological controversy, ecclesiastical leadership, Christian worship, and important events in the life of the Church.
The letters provide a complementary perspective. They place Gregory’s theological concerns within the relationships and circumstances of his own life, offering glimpses of his friendships, conflicts, pastoral responsibilities, and involvement in the affairs of the wider Church.
This edition, Select Letters and Orations of Gregory Nazianzen, presents the Gregory material found in Volume 7 of the Nicene and Post-Nicene Fathers, Second Series. It preserves the historic NPNF translation and organization while presenting the material in a convenient modern edition.
Gregory’s writings remain important sources for the study of fourth-century Christianity, the development of Trinitarian theology, the Cappadocian Fathers, and the history of the Church in the generations following Nicaea.
