“From the history of the Ecumenical Councils of the 4th and 5th centuries” – a book written by professor of the Moscow Theological Academy Alexei Petrovich Lebedev (1845-1908) in response to critical comments on his doctoral dissertation “Ecumenical Councils of the 4th and 5th centuries” from Professor Moscow University Archpriest A.M. Ivantsova-Platonov. The genre of “anti-criticism” and scientific passion (almost youthful), the unevenness of personal relations with his opponent, allowed A.P. Lebedev to express in this work many important and interesting thoughts concerning both the given scientific topic and church-historical science in general and his own creative method in particular. These are precisely the thoughts that are expressed only once, and never in ordinary, “normal” works. Many of them are relevant for today’s spiritual and scientific situation. The study also provides extensive additional and clarifying information on previous facts on the history of the Ecumenical Councils of the 4th and 5th centuries.

The book also contains the answer of Rev. A.M. Ivantsov-Platonov, a new review of him by the same A.P. Lebedev and applications concerning the history of this famous controversy. “From the history of the Ecumenical Councils of the 4th and 5th centuries” is published as part of a collection of church historical works by the remarkable Russian Church historian A.P. Lebedeva (1845-1908).
