Clement of Alexandria, the famous Father of the Church, who lived in Alexandria in the mid-2nd - early 3rd centuries, is rightfully considered one of the creators of Christian philosophical doctrine. According to some sources, it was he who founded the first Christian educational institution in history, the Catechetical School, the same one that was later headed by the famous Christian thinker and apologist Origen. Clement’s main work, “Stromata,” is surprisingly in tune with modern times. In addition to answers to pressing ethical questions, the reader will find in it a lot of interesting historical data and will receive information about contemporary Gnosticism, neo-Pythagoreanism and middle Platonism. Without a doubt, the first commented edition of “Stromat” in Russian will be useful both to everyone interested in Christian philosophy and theology, and to a wide range of readers.
