Saint Theodore, Archbishop of Constantinople, was a native of Constantinople, led a pious life, was ordained as a priest and served in the cathedral of Hagia Sophia, where he was also the keeper of the sacred vessels.
In the year 676 he was chosen to be Patriarch of Constantinople, although after two years he was deposed because of slander. But truth triumphed, and Saint Theodore was restored to the Patriarchal throne in 683. He then guided the Church of Constantinople to the very end of his life. He died around the year 686.
