Sophiology
Sophiology (Russian: Софиология; by detractors also called Sophianism (Софианство) or Sophism (Софизм)) is a controversial school of thought in the Russian Orthodox tradition of Eastern Orthodox Christianity that holds that Divine Wisdom (or Sophia—Greek: σοφία; literally translatable to "wisdom") is to be identified with God's essence, and that this Divine Wisdom is in some way expressed in the world as 'creaturely' wisdom. This notion has often been characterized as introducing a feminine "fourth hypostasis" into the Trinity.
