Give Hagia Sophia back to the Orthodox Church! Let it be what it was built to be—a house of God and a center of Orthodox Belief!
It’s just about the largest building still intact from ancient times. The maintenance costs would bankrupt Orthodoxy in Turkey.
Christians should take the same position with respect to Hagia Sophia as the Muslims take with respect to the “Al Aqsa Mosque - with FAR more justification.
