St. Gregory Palamas ca. 1296-1359
Those who do not belong to the Truth do not belong to the Church of Christ either; and all the more so if they speak falsely of themselves by calling themselves, or are called by each other, holy pastors and hierarchs; because it has been instilled in us that Christianity is characterized not by persons, but by truth and exactitude of Faith. (Refutation of the Letter of Patriarch Ignatios)
