De Sales' classic has been described as "œa masterpiece of psychology, practical morality, and common sense"� and, after The Bible and The Imitation of Christ, is the widest read spiritual book of all time. Unlike many others, Devout Life was written specifically for laypersons and it demonstrates a rare sensitivity to the demands of life in a world that is often antagonistic to spirituality. In this first-of-its-kind edition, Fr. John-Julian offers a fresh translation, a most thorough historical introduction, and notes explaining points of language and theology along the way.
