This famous and much-loved little treatise, De Adhaerendo Deo (On Cleaving to God), has been attributed to Albert the Great, but the identi-fication of Albert as the author has long been disputed, and it has been shown that it was written by Johannes von Kastl, a Bene-dictine monk from Kastl in Bavaria who was perhaps prior there c.1399. The Latin text of which this is a translation is found in volume 37 of Albert’s Opera Omnia published in Paris in 1898.

The Rev. John Henry Richards, ma, bd, was an Anglican priest born in 1934 who was ordained a deacon in Llandaff in 1977 and a priest there in 1978. He served in Maesteg, Cardiff, Penmark, and Stackpile Elidor until his retire-ment in 1999, and died in 2017. He is known for his English translations of the Sanskrit Ashtavakra Gita and Vive-kachudamani, of the Pali Dhammapada, and of the medieval Latin De Adhaerendo Deo, all of which he put in the public domain and distributed on the Internet in the late 1990s.
