Ecclesiastical History, Dialogues, and Letters

by Theodoret

This modernized edition of Theodoret of Cyrus’s writings offers an invaluable window into the theological controversies and ecclesiastical life of the fourth and fifth centuries. As a bishop, theologian, and historian, Theodoret preserved firsthand accounts of critical events following the Council of Nicaea, including the struggles against Arianism and the debates that led to the Council of Chalcedon. His *Ecclesiastical History* continues the work of earlier historians, drawing upon now-lost sources to chronicle bishops, emperors, and doctrinal developments vital to Nicene Christianity. The *Dialogues* defend the distinction between Christ’s divine and human natures, playing a key role in Christological discussions of the period, while his letters reveal his pastoral engagement with the church’s practical affairs. Carefully revised from the classic Nicene and Post-Nicene Fathers translation, this edition enhances readability and accessibility, making Theodoret’s significant contributions essential for students of church history, patristics, and historical theology.
