For your delectation:
I taught a course on Christology last spring, and in preparation I read a lot about St. Cyril of Alexandria. Three books are especially memorable from that time: Cyril’s treatise On the Unity of Christ, Christ in Eastern Christian Thought by John Meyendorff, and St. Cyril of Alexandria: The Christological Controversy by John McGuckin.
I also read a few books this year from and about the Church of England and the Anglican Communion, as I continue to try to figure out where I “fit” in Anglicanism. Three books stand out in that category: Choose Life: Christmas and Easter Sermons in Canterbury Cathedral by Rowan Williams, The Book of Common Prayer: A Biography by Alan Jacobs, and the wonderfully illuminating and (for me) comforting Michael Ramsey: A Life by Owen Chadwick.
more (I feel weird putting this under “mackerel-snapping,” but I have no sufficiently ecumenical category! THIS IS HOW WARS START)
