This famous and much loved little treatise, On Cleaving to God, (De Adhaerendo Deo) has always been attributed to Saint Albert the Great, who lived from about 1200 to 1280, and was one of the most respected theologians of his time. He was moreover a voluminous writer in the scholastic tradition, and, amongst other things, Bishop of Ratisbonne and one of the teachers of Eckhart at Paris University.
