If you want to be technical about it, Jewish sects originate in Christ. E.g., "I am the alpha and omega."
It is just a modern semantic thing to says Christianity arose out of Judaism which results from a sort of materialist historical perspective but which is theological incorrect. (Even going by materialist argument, modern Jews are nothing like ancient Hebrews. At any rate, the semantics are all wrong.)
Judaism is a lot older than Christianity. FACT. The Old Testament (Judaism) comes before the New Testament ((Christian), thats why its called New!
Kyle, its not about semantics. Jewish sects do not originate in Christ, its the other way round. It isnt a modern semantic thing. Are you saying the Bible is chronologically wrong?
