The Current Reading List.

It's actually much longer than this, but here is what is in heaviest rotation:

1. Transfiguration, by the late Melkite Archbishop Joseph Raya. This shepherd's message deserves a wider hearing.

2. I Believe in the Holy Spirit by the late Yves Congar. I know, Congar can be controversial. I roll my eyes at the occasional genuflection before the "assured results of critical scholarship," but apart from that, it's very worthwhile. The origins of the Western Church's continuing conflation/totemization of the Third Person with/by ecclesiastical figures and (self-interested) clerical initiatives can be found in Volume 1, too. 

3. The Saint by Dan Abnett. The Gaunt's Ghosts books are essential 40K reading, and Abnett never disappoints. 

4. Francis of Assisi: A New Biography by Augustine Thompson, O.P. The focus of the Poverello was considerably different from that of the figure created either by hagiography or the contemporary secular imagination.
