The Apocalypse in the Teachings of Ancient Christianity is the first complete Orthodox commentary on the book of Revelation in the English language. As the only prophetic book of the New Testament, the Revelation of St. John the Theologian is a book of deep mysteries concerning the beginning and end of all things and the ultimate purpose of the world and man. The Apocalypse examines these writings verse by verse and helps the reader interpret and understand the difficult imagery and symbolism.
