St. Eusebius of Doryleum

“The Apostolic throne has been wont from the beginning to defend those who are suffering injustice. I entreat Your Blessedness, give me back the dignity of my episcopate and communion with yourself, by letters from you to my lowliness bestowing on me my rank and communion.” (Eusebius of Doryleum to Pope Leo [A.D. 450]).
