Was Jesus really a mystical man created specifically to be THE son of god, or do you think that he is simply the person in history who has most greatly understood that he is A son of god like the rest of us?

Why are Christians, Muslims, and Jews different? Why don't you all make up and accept you're all worshipping the same god? It seems childish and very 'dark ages'. I was bought up a Quaker, and kind of hover on the edge of being a christian. But the irony of there being the holy trinity and there being trinity of abrahamic religions has always held me back.
Why do most christian denominations have blokes in funny clothes? God created all and all mankind equally - going to theology school may teach incredible amounts of theology and ideas, but does it really bring one closer to the divinity and oneness of God than any one else?
Why does christianity look down on sex, drugs and rock and roll? I know its a trite phrase but aren't they when part of an informed choice and in sensible moderation, a healthy expression of the fortitude of the human spirit? I don't advocate smack, or crack or ought like that but a few tokes or a bit of contraception never hurt any one.

How many sacraments are listed in the Bible? I ask this question because it's seems every denominations has a different point of view. Do some no longer apply, and if so, please explain.

Thanks

Can God make a rock so big that even he can't pick it up?
