Years ago I talked with a Ruthenian Byzantine Catholic priest, who said that the saints would be a major problem for him in reunification because there are some Orthodox saints – e.g. Alexis Toth – who are recognized as saints largely because they persuaded many Eastern Catholics to leave the Catholic church and become Orthodox (or, if you’re looking at it the other way, I suppose one would say ‘had them come home to Orthodoxy.’ I have no desire to enter into polemics here). So there’s that. I guess one could come up with a formula whereby sincerity would matter regardless of who was ‘right,’ but under that standard couldn’t Martin Luther be a saint?
