On the Unity of Christ (Popular Patristics)

In the early fifth century the Christian world was racked by one of the fiercest theological disputes it had known since the Arian crisis of the previous century. The center of debate turned on the nature of the personhood of Christ, and how divine and human characteristics could combine in Jesus without rendering his subjectivity hopelessly divided, or without reducing his authentic humanness to an insubstantiality. St Cyril is, arguably, the most important patristic theologian ever to deal with the issues of Christology. The text here translated is one of his most important and approachable writings, composed in the aftermath of the Council of Ephesus (431) to explain his doctrine to an international audience.
