I don't see what the real point of such straining to venerate heretics is all about - are there not enough unequivocally Orthodox persons worthy of our recognition?
All that is not within the Church is anathema. That is a grave thing to say, but needs to be qualified. "Anathema" means cut off (distinguished and separated) and held up. "Held up" to what? God's judgement. Why? Because persons/ideas outside of the Church, the Ark of Salvation, are in some essential way at odds with the Church (by not being in Her), and their way is not the way we know (and the only way given by God by which we may be saved) leads to salvation. Thus, we do not say "they're in hell" - rather, we clearly recognize they're not Orthodox, and leave them in God's hands, for He is their Lord and judge.
As such, such persons/ideas should not be toyed with or held as something reconcilable or to be ammended to Orthodoxy. While we may privately hope they somehow found their way to God, in His great mercy (indeed, how can we not want this to be possible for everyone?), granting them the cult of true Saints (prayers for their intercession, even veneration of images made of them) is an abbheration and should be avoided.
P.S. - Bobby, I haven't been RC for a long time. As for my status, I'm a catechuman.
