Jews and Christians worship the same God

I'll clarify a few things first, before I start my argument I only intend to mean that "Jesus is a false Messiah and Christianity therefore is a false religion" insofar as it would concern Judaism [he is not the Messiah referred to in the Tanakh]. This is no way means that Christianity is not a valid religion, and that Jesus (in the eyes of Christianity) is our Lord and Savior, Christ, King of the Jews, Son of God, Son of Man, and Lamb of God, Immanuel (God with us), and the Messiah of the Christians (with no connection to the Messiah of the Jews) "Some points are not clear" - What I'm saying here, is basically, they are in fact two ENTIRELY separate religions, and there are NO BONDS between them at all (religiously)... however, once a Jew accepts Jesus as his Lord and Savior, he thereby becomes a Christian and is no longer a Jew. Hence, Jesus was not a Jew (religious, not ethnic, obviously). He could be argued to be one, much in the way that Julius Caesar is not the first Emperor of Rome, but, in fact, Julius Caesar was de facto the first Emperor of Rome, he just never acquired the title. I'm saying, after the completion of Jesus's journey, he must, in fact be a Christian, if he believes in his own divinity and not a Jew(religiously) as popular culture has called him (though, again, he was still ethnically a Jew). It is not relavent to this debate, and if you would like to on another occasion argue the authenticity of the Bible, I would be happy to, but as I listed in the challenge, we accept that both the Old Testament and New Testament are true. (Though, I should have specified, when speaking from the Jewish Point of view, the Tanakh is true, when speaking from a Christian point of view the New Testament is true) I hope I answered all my opponents questions, and now onto my arguments. First, I will argue from the viewpoint of the Jews (R2). In the next round, I will argue from the viewpoint of the Christians (R3), and the final round of arguments I will rebut, clarify and combine the arguments as is necessary to fully get a breadth of the debate (R4)... then, of course, the conclusion which will have no new arguments Jews - For starters, for anyone in Christianity who believes that Jesus was indeed God, Deuteronomy 6:4 clearly states: "Hear, O Israel: The Lord our God, the Lord is one!". Also, no where in the Tanakh when talking about the Messiah, does it say that he will be (1) God incarnate (2) The Salvation (3) Resurrected and Opening the Gates to Heaven (4) He will be crucified Indeed, it warns against those who are crucified Deuteronomy 18:20 But the prophet who presumes to speak a word in My name, which I have not commanded him to speak, or who speaks in the name of other gods, that prophet shall die. (Which, regardless of the resurrection, he most certainly died) It's not hard to imagine that (given only the Tanakh) that Jesus would not be their Messiah. It requires the New Testament to give that picture. Which, I will talk about later, once the New Testament is in the picture, there are many things in that which refute the Old Testament veracity. I'll go on to explain more, It is hard to argue that Jesus brought about the "Messianic Age" prophesied in the Tanakh. At least, so far as we can tell on Earth. The God of the Tanakh is one that is very different then the one that Jesus touted. As Psalms 119:89 claims "Your word, O LORD, is eternal; it stands firm in the heavens." However, Jesus would go on to claim that many things that God proclaimed no longer stood. He worked on the Sabbath and promoted others to do so as well John 5. In Matthew 5, when Jesus gives his Antitheses. Compare Exodus:21:23-25 "But if there is serious injury, you are to take life for life, eye for eye, tooth for tooth, hand for hand, foot for foot, burn for burn, wound for wound, bruise for bruise." to Math 5:38-39 ""You have heard that it was said, "Eye for eye, and tooth for tooth." But I tell you, do not resist an evil person. If anyone slaps you on the right cheek, turn to them the other cheek also. These are directly opposing commandments These are things that change the word of God, which according to the Tanakh, isn't allowed by the Word of God. That isn't to say that he didn't fulfill some of the prophecies, as many people in the history of world have, but the Messiah is to fulfill all the prophecies, and Jesus failed to do that. There really is less to prove from the Judaism side, as clearly those who only follow the Tanakh do not recognize Jesus as the Messiah, let alone the Lord and Savior that Christianity touts him as, so... As it appears my opponent agrees with Messianic Judaism, I would rather prefer the Burden of Proof on this side to be on him. If you are to only follow the Tanakh, why should Jesus be considered the Messiah? (You can use references in the New Testament for Jesus's actions and sayings, but you can't say "The New Testament says he is!" or "The New Testaments says the Tanakh says so and so", when the Tanakh doesn't actually say that.) I'll stop this side of the debate here, and wait to continue onto the New Testament and why it is an ENTIRELY separate religion. So, if you will, refute my arguments from this round, and also give me reasons why Jews should recognize Jesus as the Messiah as he is defined in the Tanakh.
