The work presented by Metropolitan Mar Severios is a valuable contribution on behalf of churches adhering to miaphysite Christology in the context of ecumenical conversations between church representatives of various christological positions. "Over the course of his ten `Discourses against Habib' Philoxenus quotes at some length Habib's arguments before countering them with his own response. ... The reader will find the arguments of both sides set out with admirable clarity and objectivity, and it is to be greatly hoped that this monograph, with its constructive approach, will contribute towards a better understanding of the two different approaches, miaphysite and dyophysite, to the mystery of the Incarnation."
