There is no book in English that treats the whole of Cyril's theological thought. In the past scholars have normally focused on Cyril's Christology and left largely unexamined the remainder of his theological thought. Thus the English-speaking scholarly community has never fully appreciated the breadth, the depth and the immense significance of Cyril's theology. This book is therefore unique. The editors have brought together many of the foremost experts on Cyril. This international team examines all the major facets of his theology, and here for the first time reveals the theology of Cyril of Alexandria as a magisterial whole.
