"Father George Papademetriou off ers in his illuminating study a splendid theological exposition written in lucid language on some very diffi cult material dealing with Hesychasm and mystical theology. Father Papademetriou's book off ers the serious student the opportunity to familiarize himself with the life and works of the saint. Th e reader is succinctly introduced to the theology of St. Gregory Palamas with clarity and reasonableness." John Rexine
