First of all, some traditions are biblical. Some aren't. Secondly, when I say "historically" that can include OT/NT times and practices. The Bible is, after all, an historical document.
Finally, Protestants and Catholics hold some traditions in common, correct? We don't need to wrangle over what we hold in common. So I was appealing to that common ground.
I guess I can't even appeal to common-ground tradition without somebody seeing an inconsistency.
Well, yes, it is inconsistent when coming from a Sola Scriptura voice. I welcome it of course, and hope to expand it for you incrementally. :)
Thanks for your reply.
