Muffled
Jesus in me
I guess if I follewed the teaching of someone and they came back and said that that was not what they were teaching, I would have to believe him. No one knows better than what he taught than himself. I don't know that I would follow the religion he pointed to but I would stop with the one he claimed was right. More than likely I would switch since he actually cam back from the dead though.
I think this brings up the very real problem of the integrity of the religious teacher. If he returns treaching something anti-thetical, his teaching in either case would become suspect. However if Mohammed came back and said I have seen the light, that Jesus is the only savior I would not construe that as anti-thetical to his previous teaching, but then I am a Christian and have a different perspective on Islam from most Muslims.
