In the various descriptions I've read, the "Branch Theory" which Orthodoxy rejects was described as the view that the EOC, OOC, and RCC are all branches of the same trunk (Christ), to the degree that they maintain apostolic succession and the teachings of the ancient church (Protestant churches, which mostly don't hold any form of apostolic succession, get left out). That doesn't sound quite the same as what the Bishop said, or what Amy echoed, which puts the Orthodox Church as the trunk or root (being the "Body of Christ"). As a soon-to-be-but-not-yet-a-catechumen, I'm not exactly qualified to critique a Bishop's remarks. But it does seem that his particular emphases would make a great deal of difference. What does it mean, to him, that the various denominations are "branches"? Is it to say that they are legitimate, though of lesser fulness than the trunk? Or merely that all that is true within them, any Life that is found there, derives in some way from Orthodoxy (which sounds like what Amy was saying)? Or maybe something else entirely? That would seem to me to make a big difference in interpretation. In Christ, Mike
