I'm curious as to whether anyone knows of an (at least somewhat) scholarly book detailing the history of the concept of deification within Christian thought. Most of the books I've read or looked over seem to be light on the history of it, and usually just mention a few Scripture passages (Ps. 82:6; 2 Pet. 1:4; etc.) and a few Church Fathers (Sts. Irenaeus, Athanasius, etc.) as a brief basis for the bulk of the work, which is a discussion about the meaning of the concept and how it is worked out (theologically and practically). What I'm more interested in is who used the concept in the early Church and to what extent, how it became a forgotten or unused concept for centuries in some parts of Orthodoxy, how and where the concept came back into vogue in the 20th century, and why it has now come to be viewed, for at least some, as the Orthodox concept of salvation (rather than merely one way of understanding salvation among many).
