His academic interests include patristic exegesis and its reception, as well as the role of scriptural interpretation in the spiritual life. His dissertation examines the early history and manuscripts of the Homiliary of Paul the Deacon, an anthology of patristic homilies and sermons authorized by Charlemagne for use in the Daily Office. It became one of the most widely-used books in the Middle Ages and was the backbone of the Roman Breviary.
Before his arrival at Cambridge, Zachary completed his B.A. in Biblical Studies at Evangel University and his M.Div. at Harvard Divinity School. During his time at Harvard, he served as the Kellogg Fellow at the Episcopal Chaplaincy at Harvard. He is the author of various articles, short essays, and reviews, and he is co-editor of two volumes in the new Studies in Episcopal and Anglican Theology series edited by C.K. Robertson.
He and his wife, Melissa, are natives of Peoria, Illinois, that most normal of American towns. They made their way to Anglicanism via a long pilgrimage through nearly every other Christian denomination, beginning with the Assemblies of God, a process which has given them a healthy regard for ecumenism, a love for good liturgy, and a significant appetite for theological discussion. They are, as well, studied practitioners of the culinary arts.
