"Defending Constantine"

After reading this, at First Things, I ordered my own copy of Peter Leithart's Defending Constantine.  The book is reviewed by Stanley Hauerwas, here, who notes that "[a]sking me to write a review of Peter Leithart's defense of Emperor Con­stantine may seem like asking the fox to inspect the henhouse."  There are additional discussions at the "Christianbook.com Academics" forum.  I also thought that this discussion, by Matthew Nickoloff (who has a very interesting blog), helpful.
