They do not have apostolic succession.
Actually, according to your church, they do.
Michael,
Does Orthodoxy deny or accept these claims to AS?
Jon
Orthodoxy regards them as irrelevant.
Because they are outside Holy Orthodoxy, which the Holy Spirit established at Pentecost.
Any one bishop who does not teach orthodox Truth and/or does not have an Orthodox flock is not in the Orthodox church. We do not speculate upon their validity. I think some have referred to this as the Cyprianic approach.
Thus, there is no prospect of eastern vaganteism, either.
Those vagantes who claim to have “valid succession” are using a Roman Catholic standard to establish that, which we do not accept. So one might find some such vagantes who claim to be Orthodox, quite often they are former Anglicans or Roman Catholics who have fallen in love with the eastern rites and traditions. We are flattered, but that does not make them Orthodox.
And so ultimately Holy Orthodoxy does not judge non-Orthodox orders and does not expect non-Orthodox to pronounce on Orthodox orders. This is true whether one is Roman Catholic, Lutheran, Anglican etc.
If a consecration is valid, that means the Holy Spirit, the Paraclete, has come down upon the candidate through the laying-on of hands. No one, not even a Pope, can prevent that if this is what God wants to do. And if that truly is
what God does no man, including no Pope, can have the temerity to call it invalid nor illicit, for no man judges God. This is not magic, like the summoning and dismissing of spirits with special words. This is a holy sacrament of God we are discussing here!
So quite frankly, we do not know what goes on out there beyond the Orthodox communion, the Holy Spirit does what He wills. Better to not judge or opine one way or the other. If churchmen wish to join with Holy Orthodoxy, and they are accepted, they will be received in such a way that we expect the Holy Spirit will make up for any possible deficiencies, although we cannot be sure these might be (or not be).
The fact that the Roman Catholic church thinks Orthodox orders are valid is of no importance to Orthodox. We wonder why they consider it necessary to say such a thing, we never had any doubts at all about it.
Any communion that allows another church set the standard for it’s own legitimacy has bigger problems than Apostolic Succession.
