What is the relationship of the Hagia Sophia (or the Holy Wisdom) to the Ecumenical Patriarchate?
A. Hagia Sophia is one of the architectural wonders of the early Church. It housed some of the most magnificent mosaics, some of which survive to this day, and was the center of impressive liturgical worship. It was here that Prince Vladimir in the 10th century sent his envoys to witness the liturgy, as a result of which all of Russia was Christianized. Converted to a mosque in 1453, today it is a museum.
