Sergei Bulgakov

Sergei Nikolayevich Bulgakov (; ; – 13 July 1944) was a Russian Orthodox theologian, priest, philosopher, and economist. Orthodox writer and scholar David Bentley Hart has said that Bulgakov was "the greatest systematic theologian of the twentieth century." Father Sergei Bulgakov also served as a spiritual father and confessor to Mother Maria Skobtsova (who was canonized a saint by the Holy Synod of the Ecumenical Patriarchate on 16 January 2004).

Bulgakov is best known for his teaching about Sophia the Wisdom of God, which received mixed reception; it was condemned by the Moscow Patriarchate in 1935, but without accusations of heresy. Provided by Wikipedia
