RS, I've heard that reason for pushing celibacy before and have no reason to doubt it at all. I also have no reason to question the Latin Church's discipline. I doubt many, if any, Orthodox Christians question Rome's absolute right to set such disciplines for its particular church. So far as I know, Rome doesn't seek to impose that discipline on churches in communion with it in their own territories, let alone on Orthodoxy if a reunion ever occurs. I do question the reasoning of the author of this article and find his abuse of historic Orthopraxis offensive.
It is also true that our church also had the tradtion of maintaining a distance between itself and imperial authority. One of the consequences of the Reformation. was an acceleration of the a weakening of the papacy that had begun began at the turn of the 14th Century, was a radical caesaropapism. I don't think that even in the Russian Church were the clergy so beholden to the crown as they were in England. On the other hand., western understanding of eastern Christianity is quite limited. Even under the most powerful Byzantine emperors, the clergy acted with great independence, so that they could resist strongly the iconoclasm of Leo the Isaurian.
