Let me throw something out there for your consideration. It is my understanding that the canons of the Church, up to the Seventh Ecumenical Council, never forbade married bishops. The only restrictions I've found after the Apostolic canons that forbade separating a man and his wife, were couple of canons at the Council at Trullo that said (a) married bishops must physically separate from their wives and both shall live celibate lives, and (b) if a married man were to become a bishop, he and his wife are to likewise be separated and live celibate lives. It can certainly be argued that the second canon does indeed makes it impossible for a bishop to live a married life at and after his ordination. However, it can also be argued that a married man can become a bishop if he and his wife agree to live separately and not have sexual relations as husband and wife; that is, the bishop is a married man in name only and not in actual practice. It is my opinion that the reasons for this development, which is contrary to the Holy Scriptures and the Apostolic Canons, were rooted not in theology or ecclesiology but in practical concerns of state and church of that time. These canons are therefore temporary (as stated in the first instance) and peculiar to the past. What we now have is largely inertia and, as a good thing, the reluctance to change an age old practice and those practical considerations that are always brought up when the subject comes up, such as how can you be married when you are always working and traveling?.
