The Church in the world is Sophia in process of becoming, according to the double impulse of creation and deification; the former imposes the conditions of the latter, the latter constitutes the fulfillment of the former.
Bulgakov identifies the Church ontologically with Sophia — the divine-human principle becoming itself in history through creation and deification, not as metaphor but as theological reality.
