I assume the question means Judaism as taught in the Old Testament concerning the nation of Israel, and Christianity as taught in the New Testament. Each of these terms may have a multitude of meanings and connotations outside the Bible, so I'll limit my opinion to what the Bible says. Put simply, Judaism does not acknowledge Jesus (Yeshua) as the Messiah. Their rejection of him basically centers around one criterion: the Messiah will bring peace to Israel and defeat its enemies. Anyone who didn't or doesn't accomplish this must not be the Messiah. Christianity identifies Jesus as the Messiah, citing the fulfillment of many prophecies in great detail. The fact that he didn't bring peace to Israel is itself a fulfillment of prophecy, especially those by the prophet Isaiah. Some prophecies refer to the conquering King who brings peace to Israel, but others speak of the Messiah's suffering and death. Christians hold that these two sets of seemingly conflicting prophecies are reconciled by two advents or 'comings': the Messiah would come first to suffer for sins, then later to bring peace to Israel. To the Jews, Jesus was a blasphemer for claiming to be God, which is why they wanted him put to death. (Note: please do not read anti-Semitism into that statement; the New Testament lays responsibility for Jesus' death at the feet of every human being that will ever have lived.) To the Christians, Jesus is the Messiah who will soon return to bring peace. All this, of course, is my personal opinion, and is admittedly an over-simplification. But it accurately describes the way each side views Jesus.

OutThere's answer is slightly inaccurate, in that the statement is made that the Jewish objection to Jesus: centers around one criterion: the Messiah will bring peace to Israel and defeat its enemies. Anyone who didn't or doesn't accomplish this must not be the Messiah. I would modify this by saying that, from a knowledge of Hebrew, and with the text of the original prophecies in hand, there is no way that Jesus fulfilled ANY of the prophecies concerning the Messiah, including his lineage, if the Christian scriptures are to be believed. Without intending to step too painfully on anyones' toes, I'll just point you to the Jews for Judaism site, where this is discussed in much greater detail: http://www.jewsforjudaism.org/

To put it as simply as possible: Jews do not believe in a Trinity. They don't think Jesus is God, the son of God, or in any way related to God. So Judaism could not possibly perceive Jesus the way Christianity does... it doesn't believe certain things about him that are at the very heart of Christianity. To the Jews, Jesus was just another Jewish man. And then he became a Jewish man who challenged the establishment, acquired a following, and was seen as somewhat of a threat to the status quo. And as for what happened from that point on... the Crucifixion and Resurrection (and the importance attached to them) are absolutely central to Christian faith, but they can't be to Judaism because Judaism doesn't attach the same importance to the man involved. I assume that Judaism wouldn't even believe that there was a Resurrection...

The genealogies of Jesus were not presented as "proof" of his being Messiah until after he was dead, likely not until at least 45, possibly as long as 100 *years* after he was killed (assuming he really existed). That said, the notion that the Jews couldn't disprove his genealogy and thereby prove that Jesus wasn't the Messiah, at that point the question was utterly moot. Beyond that, the fact that Jesus' genealogy is inconsistent between Matthew and Luke should give those who push it as "proof" pause to think, especially in light of the fact that _both_ of the genealogies actually prove that Jesus could _not_ have been the messiah. All of that said, genealogy is only one of many aspects required to determine whether or not someone is the messiah. As I've said previously, here and elsewhere, this stuff is covered in depth on any number of sites, including http://www.jewsforjudaism.org/ ~Tomer

Jews do not recognize Jesus as a Messiah because he was nothing like the Messiah the Jews two thousand years ago were hoping for. They wanted a man of war who would defeat the Romans and drive them from the Holy Land,. not a man of peace. In the Bible, it is written the Messiah would also bring everlasting peace, turn the deserts into gardens and bring peace to that part of the world. Its obvious that never happened. Jesus is the embodiment of wishful thinking. The things he is quoted as having said, are all very nice but these are statements the writers never heard because most of the apostles never met Jesus and therefore never heard him speak. What they knew of him came second and third hand and when that happens, stories undergo major changes. Most Jews who look upon Jesus, consider him a gentle Jew who was not divine in any way but who had a good heart. And they see him as a Jew who may have been taken advantage of by his "friends" and who paid the ultimate price. In ancient days, to claim to be royalty was, in Roman Law, a capital crime, punishable by death. Herod demanded that Jesus deny claims by others that he was "King of the Jews" because the only king aroiund there was Herod and no one else. Jesus did not confirm or deny the claim. And that sealed his fate. The rest of the story was in the hands of some elderly men, the aging apostles, who, in all liklihood with failing memories, completed in their writings. With senilty, arteriosclerosis or possibly even alzheimers, can we rely upon their recollections? And finally, with problems in translations from one language to another, the stories have undergone changes over the centuries.

Some major ones have been brought up by TShilo, Karawan, and OutThere. There is another I would like to mention as well: Jews believe Jesus did not rise from the dead as He prophesied. It is taught that His disciples stole Him away, despite the legion of Roman soldiers guarding the tomb, the fact that the Pharisees were expecting it because of His prophecies, the disheartened nature of His disciples upon believing Him not the Messiah they'd expected (as told in the Gospels). I don't know if it's taught in Judaism but I've also heard the theory that Jesus wasn't truly dead but somehow managed, despite being dehydrated and weak from near death, to remove 70 pounds of burial clothing and spices/body preparation devices, roll back the huge stone guarding the tomb, and then evade capture from a Roman legion, perhaps the most highly trained fighting force in history up to that time. Yes, Jews do believe Jesus didn't fulfil prophecies. They are taught not to examine certain prophetic areas of the Old Testament because they "wouldn't understand them." Personally, it sounds to me a lot like Catholocism, where the same excuse is used to keep people away from the book of Revelation and just Bible reading in general. Due to archeological evidence we do, however, know the exact dates needed to apply the Daniel 9 prophecies, which Jews are told to stay away from, of when the Messiah would be born. As Daniel 9:25 from the Ketuvin says, from the going forth of the commandment to restore and build Jerusalem (found in Neh. 2, dated "in the month of Nisan, in the twentieth year of Artaxerxes the king", or 445 B.C.) unto the Messiah the Prince shall be 69 weeks... http://www.ishwar.com/judaism/holy_ketuvim/book09/book09_009.html The 70 weeks of prophecy are weeks of years, as in the Torah, Genesis 29:26-28 shows. http://www.ishwar.com/judaism/holy_torah/book01/book01_029.html Each year is 360 days long as per the calendar then used, making for 490 years of 360 days starting at 445 BC. None of the other proclaimed Messiahs fit that time frame, save one, Jesus Christ. He fulfilled hundreds of prophecies: http://www.teachinghearts.org/dre03propchristnotes.html Some prophecies such as that of world peace are not yet filled, and as Jesus said, He didn't come to usher in an earthly kingdom, for if He had, His followers would fight for Him. He came to set up one in the hearts of men and one day will return to usher in a new creation, and then universal peace and a physical kingdom will also become a reality. Many Jews could not reconcile this idea of a peaceful Messiah with that of which they'd been thinking of, a conquering political ruler who would physically lead them to victory over their enemies like the Romans and other oppressors. However, many chose to follow Jesus, and it is why Christianity started in Israel of all places. For several hundred years there was a large contingent of Jewish Christians in Israel, after the resurrection of Jesus. More and more Jews are however coming to realize Jesus as their Messiah, and that the New Testament is not meant to insult Jews but goes out of its way to tell of fulfilled prophecies, and that as Paul says in Romans 11:2, God has not cast away His people whom He foreknew. Many of the apostles, including Paul, and many of the first Christians were Jews, for the Gospel was proclaimed first among the Jewish people as per God's plan. http://powertochange.com/changed/stelchin.html http://myspace.com/nauticalhaven

Well I had to create an account because this topic annoyed me the most. Just because we're Jews, it doesn't mean we sit around and try to disprove Jesus's being G-d's son. We go on through life and never even think about him through most of our lives-only when it comes up through gentile friends. We don't think he is because hardly any of the prophecies were completed (if any). Thirdly-we don't deny the EXISTANCE of Jesus, for us he is a MINOR rabbi/prophet.
