Intelligent Christians help please?

I hear you. I feel like that more and more everyday. It's hard to walk away because it's been so ingrained in you. You feel like you're turning your back on Jesus, because that's what they say you're doing. Most religions probably have some truth to them. I think when we die, we're all going to find out we've been mively wrong about things- even Catholics (yes, I've been raised as one).
