Please do pardon my display of ignorance about this, but I thought that the goodm people here would know for certain.
I know that the current custom is for bishops to be selected only from among monastic clergy. In some circles, I have heard this referred to as universal Orthodox custom, while in others, I have been made to understand that, prior to the Schism, practice varied from place to place, and that it was not the general practice in the Orthodox West to insist on celibate bishops, as married men were also chosen. If the latter is true, then the practice of ordaining married men to the episcopate was lost to Orthodoxy, not for doctrinal reasons, but because of an accident of history, and there would be no reason why Orthodox bishops may not be married today.
I have no personal argument either way as I don't know enough about the issues, but I thought I'd ask if there's anything else that I'm missing. Is there a canon requiring bishops to be monastics or is it really just an Eastern practice that became, de facto universal after the Schism?
Many thanks for your help.
