For the record, I am not arguing for the Eastern Orthodox. There are plenty of them here (this is their board), and they are doing a fine job of arguing for themselves. I am Oriental Orthodox -- a different communion entirely -- but I am participating in this thread nonetheless because this is one area in which we do not differ. As far as I can tell from reading about this topic in their sources and those of my own church, we have the same way of looking at the Church and the scriptures and their relationship to each other.
Well, this thread is not really about Anglicans or Episcopals or whatever, but no. It is not possible to have apostolic succession outside of having maintained the apostolic faith, so no church outside of the Orthodox Church has apostolic succession. What you are writing here reflects a very Rome-ish way of thinking about this matter, whereby apostolic succession can be maintained by whatever obscure historical links you can point to that connect an N-th generation copy (i.e., all Protestant churches, and Rome too for that matter) to the real thing. This is, at its basic level, not different than how any clearly modern, invented group justifies itself. EO, you have a lot more of these than we OO do (though we have a few), so you probably know what I'm talking about: You go to a website of some group calling itself "THE MOST TRUE HOLY APOSTOLIC GENUINE ORTHODOX CHURCH" and read what they say about themselves and their idea of succession is something ridiculous like "our heirarch, HH JOE BOB GIVENS, bumped into HAH Bartholomew I in an airport restroom once, and so we have carried that clear blessing and authority over in the establishment of our Church, the MOST TRUE AND HOLY CHURCH OF GOD EVER, EVER."
Nobody cares where you claim to have come from. They care where you are at in terms of your faith and its conformity with apostolic norms and the councils accepted by the communion. There is no mechanical view of apostolic succession such that you can sustain "validity" (to use a Roman term) outside of that.
Based on what, though? The fact that they would like it to be that way? That it fits with their preexisting way of viewing the relationship between scripture and the Church, even if that way is warped by its very existence outside of the historic mainstream of Christianity, where no such division was entertained? (And still isn't, in Orthodoxy.) I'm sorry, but I don't see why anyone anywhere should take the word of some English guy or group of them in the 16th century over our fathers St. Cyril, St. Basil, St. Gregory, St. Athanasius, etc. You really think that these saints got it wrong, and could only be corrected thirteen centuries later by some yobs who didn't speak their language, didn't grow up in their societies, didn't have their understanding of what scripture even is, and couldn't point to any source of origin beyond "We didn't like Rome, so we went off and did our own thing"? (In hundreds of different varieties, at that.)
I believe that's what the Anglicans would call "poppycock", friend.
