Just so everyone else knows: I'm not a cleric, nor a professional theologian or religious academic. I do theology the way any layman does it: reading the texts, listening to the advice of others, and thinking. By the grace of God, the voice of the Spirit is heard. Or not.
And if you believe Richard Hooker, that's the way the clerics are doing it too.
So who gets to speak for a church? Well, in episcopal polity, certainly not laymen. You have to ask a bishop, or repeat what a bishop says-- word for word. And if what the bishop says isn't firmly grounded in tradition--
Well, how do you tell that it is so grounded? Well, um, you do theology. After all, even if one bishop is just repeating something another bishop said, the predecessor has to fulfill the same test, and so forth.
So: is it actually true that in Orthodox tradition dogs are unclean animals? Well, I don't know for sure: Nick, you aren't good enough authority on your own. And even then the same problem applies to whichever bishop you end up citing. Is what he says an integral part of the tradition, or is it just a presumption or prejudice riding the genuine merit of other canons and positions?
