I would encourage anyone interested in theology to take a look at the Sergius Bulgakov Blog Conference, begun on September 29th and going to October 13, on the Land of Unlikeness. Bulgakov is one of the most important, but also most controversial, Orthodox theologians of the 20th century.
The first post is a two part introduction to Sergius Bulgakov by Cynthia Nielson: Part I and Part II.
