Synaxis of the Three Hierarchs: Basil the Great, Gregory the Theologian and John Chrysostom: During the eleventh century, disputes raged in Constantinople about which of the three hierarchs was the greatest. Dissension among Christians increased. Some called themselves Basilians, others referred to themselves as Gregorians, and others as Johnites.

By the will of God, the three hierarchs appeared to St John the Bishop of Euchaita (June 14) in the year 1084, and said that they were equal before God. ‘There are no divisions among us, and no opposition to one another.’

They ordered that the disputes should stop, and that their common commemoration should be celebrated on a single day. Bishop John chose February 12 for their joint Feast, thus ending the controversy and restoring peace.
