Talk:Sergius Bulgakov
St John Maximovich, in his book, The Orthodox Veneration of the Virgin Mary devotes an entire chapter on why the Sophiology of Sergius Bulgakov is heresy. This heresy is as destructive as the Nestorian Heresy.
The Moscow Patriachate denounced this Sophiology of Sergius Bulgakov as heretical in 1935 according to the Wikipedia and The St Herman Botherhood.
