Jesus is the Messiah. He claimed to be I AM, the Creator of all life, and proved it by coming back to life after allowing Himself to be killed. If you don’t believe it, that’s fine; Saul of Tarsus took some convincing, too. I’ll pray that your “Damascus Road” experience comes sooner rather than later.
The point I'm making is that a thousand years before chr*stianity existed, G-d spoke at Sinai. I thought chr*stianity acknowledged this; it's in your bibles. This being the case, the prior Revelation sets the criteria for any and all claimants of later "revelation." One does not accept the later revelation on its own authority and then read back the later revelation into the earlier revelation. This is a violation of every rule of logic and reason.
If chr*stianity does not claim to be the fulfillment of the earlier revelation, then it should stand on its own two feet and stop claiming to be "fulfilled" or "completed Judaism."
The "holy qur'an" claims to be divine revelation. The book of mormon claims to be divine revelation. The claims of all these "later revelations" is disputed. But the claim of the first revelation is universally acknowledged. If J*sus was indeed the "Jewish messiah," he had to have fulfilled the criteria set forth above all by the Torah and secondarily by the Prophets and Hagiographa. If he did not have to do this, if his own claims were self-authenticating, then take the "old testament" out of your bibles and leave it alone.
