Albert the Great (c. 1200–1280), called Albertus Magnus, was a German Dominican friar, philosopher, and bishop, honoured in his lifetime as Doctor universalis, the universal doctor. At Cologne and Paris he taught Thomas Aquinas and wrote on nearly every branch of learning, joining faith to careful study of nature. On Cleaving to God, a short treatise on union with God through detachment, is traditionally ascribed to him.

A little book of meditations on union with God, attributed to Albert the Great, the thirteenth-century Dominican teacher of Aquinas. On Cleaving to God urges the reader to strip away distractions, endure trials without murmuring, and cling to God alone in naked faith and love. Brief enough to read in one sitting, it has been treasured for centuries.
