Jason in New Hampshire has been looking at internet argument about religion for a while too, and he's not pleased with what he's seeing.
I live out at the Anglican/Catholic/Orthodox end of internet discussion, so the specifics of the disagreements have a different flavor. But the point about the "keyboards of the kingdom" is even more valid for us. Technically, only bishops can speak to Anglican or Catholic or Orthodox doctrine. When the rest of us do theology, it may be right, it may be wrong, but it isn't the church speaking. Therefore, it is always high time for us to get out of the cathedra and speak as if we were the ordinary mortals that, in fact, we are.
