If I'm Right, Are You Wrong?

I'm working my way through One People, Two Worlds...and I'm finding Yosef Reinman's contributions depressing. He believes so passionately in the revealed truth of Orthodox Judaism that he believes only Orthodox Judaism offers truth. Other branches of Judaism and other religions are true only in so far as they agree with his tradition.

But what's to prevent God from revealing Himself differently to different peoples and individuals? The theory behind religious pluralism is that we can judge different faiths--or different branches within a faith--only by their morals. Morality is universal, but theology is not. We can judge a faith (if, indeed, it's necessary to judge) by deeds, but not by creeds.

I understand God as the God of Israel; but that doesn't mean that a Hindu who understands God as Vishnu is wrong. Surely we can't shrink God to fit only one understanding?

Conservative Judaism and Orthodox Judaism have different ways of approaching halacha--Jewish law--but that doesn't mean one is right and the other is wrong. Surely halacha is too vast for one approach?

The I'm-right-so-you-must-be-wrong approach to life is a dangerous one. Especially when we apply it to matters we can't possibly prove. We're not going to find out the exact nature of God in this lifetime...so why not accept the possibility that views other than our own may have validity?

That seems a rational alternative to claiming views we have no hope of proving as the only truth...
