The concepts of "person" and "hypostasis" form the cornerstone of the theological edifice of Saint John of Damascus.

In the three texts that are translated and commented on in this volume, the author analyzes in a simple, understandable, and methodical manner the way the concepts of "hypostasis" and "person" are constituted in contrast to the concepts of "nature" and "essence," concepts that have served as a springboard for conflicts and heretical deviations within the Church.

Starting from ancient Greek logical thought, as this thought is transformed within the prevailing climate of the ecclesiastical body, the author achieves a Greek reading of Aristotle, interweaving Christian tradition with ancient Greek thought.
