The Church of Saint Demetrios in Thessaloniki. According to St. Gregory Palamas, St. Demetrios was graced with splendid prophetic power and was counted worthy of "the apostolic and teaching diaconate and a high position". He was full of virtues and was not inferior to the saints in asceticism "and in their radiance of life". But he was behind some, was like others; superior to some and surpassing others. He possessed many gifts.
