His translations of Aelred of Rievaulx’s Homilies on the Prophetic Burdens of Isaiah (CF 83) and of some of the liturgical sermons from Aelred’s Durham Collection (CF 80) were published by Cistercian Publications in 2018.Elias Dietz has been a monk of the Abbey of Gethsemani since 1988. He has published studies on early Cistercian authors in various journals, including Cistercian Studies Quarterly,of which he was editor from 2003 to 2007. Since 2008 he has served as abbot of his community. With regard to Isaac of Stella, his main contributions have been a study of his biography (CSQ, 2006) and an edition and translation of his Letter on the Canon of the Mass (Cîteaux, 2014). He is currently collaborating with Sources Chrétiennes on a volume of Isaac’s letters.

"This long-awaited volume allows contemporary readers to appreciate the full theological creativity and monastic wisdom of one of the greatest, but less well-known, Cistercian mystics of the twelfth century. Isaac of Stella's liturgical sermons are original, challenging, and spiritually nourishing. It is a delight to have them in a fine English translation for the first time."Bernard McGinn, Naomi Shenstone Donnelley Professor Emeritus, Divinity School, University of Chicago
