This is a simple yet very profound book about life in God as it translates into life in the world. It was written around 1350 by an anonymous author. This translation has been entitled The Theologia Germanica of Martin Luther since it is based on the Reformer's edition of 1518. Luther wrote: "next to the Bible and St. Augustine, no other book has come to my attention from which I have learned-and desired to learn-more concerning God, Christ, man and what all things are." Bengt Hoffman in his Foreword says, "Luther's kinship with this book and with Johann Tauler, as well as with some other mystics of the late Middle Ages, suggests a union in the Body of Christ, transcending ecclesial boundaries, through sapientia experimentalis, the heart's knowledge of Christ's presence here and now."
