M*W: Welcome to sciforums, Akottens! None of these religions are "true," that'w why they contradict.
Jesus, himself, never claimed or said anything. Everything Paul quoted Jesus having said was a lie. Paul never new Jesus. But, it gets deeper. Jesus never existed, and possibly neither did Paul. The latest research on these biblical characters concludes they may have been invented by the Caesars in order to control the masses when their funds ran out to pay their armies to control them.

Judaism and Islam came out of Egypt but retained their Egyptian heritage. In their early days, they were polytheistic. Abraham was polytheistic (if he existed), and it's highly doubtful.
So, what am I getting at? All religions are man-made and have no real divinity. Ancient humans feared and awed the sun, stars, planets and elements, and created stories around those sky gods. The stories changed with the movements of the planets, and new myths were created and their names were changed. There is really no such thing as religion except in the minds of the spiritually needy.
