As we all know, when someone becomes a monk, they change their name. This new name usually sticks with them for the rest of their life. However, in the case of Saint Cyril VI, he was called Abouna Mina before his papacy. Pope Shenouda III was called Abouna Antonios before his episcopacy. But Pope Tawadros II kept his monastic name. Why do some change their names when they become bishops?
PS: I am absolutely not trying to bash anyone or anything, I’m just confused on the naming rules.
