Sophiology (Russian: Софиология, by detractors also called Sophianism Софианство or Sophism Софизм) is a controversial school of thought in Russian Orthodoxy, concerned with the interpretation of Holy Wisdom (Hagia Sophia) which has been misunderstood as a feminine "fourth hypostasis" .
The controversy has roots in the early modern period, but sophiology as a theological doctrine was formulated during the 1890s to 1910s by Vladimir Solovyov (1853–1900), Pavel Florensky (1882–1937) and Sergey Bulgakov (1871–1944).
Thomas Merton studied the Russian Sophiologists and praised Sophia in his poem titled "Hagia Sophia" (1963).
