"...as in the sophiology of Father Bulgakov, a modern Russian theologian whose teaching, like that of Origen, reveals the dangers of the eastern approach, or, rather, the snares into which the Russian thinker is prone to stumble."
Vladimir Lossky, God in Trinity, Chapter 3 of The Mystical Theology of the Eastern Church (St. Vladimir’s Seminary Press: Crestwood, NY, 1976), pp. 44-67.
"The Orthodox Church exonerated Sergius Bulgakov in 1937 from the charges of heresy which may have been all too hastily brought against him by Metropolitan Sergius and by the Karlovtsy synod. The decree of Metropolitan Sergius, in the absence of the reunion of the synod in Moscow, had no legal force...the charges against Bulgakov done by the Karlovtsy synod were also inadmissible since this synod had no canonical authority. These charges may also have been based in political-ecclesiological animosities rather than in theological discourse. The synodal commission convoked by Metropolitan Evlogy removed all suspicion of heresy from the writings of Bulgakov against the accusations of Vladimir Lossky and of Georges Florovsky and Sergius Chetverikov."
