You think that the fact that J*sus and the disciples were Jewish mean that their teaching couldn't have been heretical? Then that means that Luther couldn't have been a heretic because he was Catholic!
I don't get it. The hypocrisy of Catholics and Orthodox chr*stians is absolutely palpable, yet you don't see it. One minute you're attacking sola scriptura and insisting on an official Biblical interpretation. Then when someone brings up the unpleasant fact that this interpretation was already in existence from Mt. Sinai you suddenly become "simple Southern Baptists" and start "proving" the new testament's claims by merely quoting them!
Bottom line: if there's a tradition, it's from Sinai. If the tradition from Sinai is no longer valid, then no tradition is.
If you support proselytization of Jews, don't pitch a fit when Protestants target you.
But some of that tradition from Sinai held that it, itself would be set aside when the Messiah came.
I respect your traditionalism here, but you are mistaken in trying to characterize that tradition as stating unequivocally that the Mosaic Law was for all time. Tradition differed on this point.
Luther and his views were condemned by the duly constituted Catholic authority as heretical.
By what *duly constituted* Jewish authority was Christ/Christianity declared heretical?
