The book is a translation from Serbian of the doctoral dissertation of Hieromonk Afanasy (Jevtic) “The Ecclesiology of the Apostle Paul according to St. John Chrysostom,” which was originally written and published in Athens in Greek in 1967. The author, now world-famous archpastor and theologian Bishop Athanasius, has expanded his work in our time to publish it in the Serbian language. This book will allow the reader to come into contact with a comprehensive patristic understanding of the Church as the Theanthropic Body of Christ the Savior. Intended for everyone interested in Orthodox theology.
