Now do you as a Jew worship Jesus? It is a requirement of Orthodox Christianity. It would appear to be an abomination to an Orthodox Jew.
So, with that in mind, do we worshp the same God? Is there really a meeting of the minds on who this God person is?
That is one angle to look at it, and it is the angle that, from the standpoint of Judaism, makes Christianity look problematic.
On the other hand, though, orthodox Christianity does teach that Jesus is God (specifically, the second person of the trinity) made flesh. Now, you and I disagree about whether God is one person or three, and we disagree about whether God became man. But the God we are talking about -- the God who we agree acts in the Hebrew scriptures, and the God Christians believe became incarnate in Jesus -- is one and the same. We disagree about God's nature, and about what He did, but we are still talking about the same Being.
Let me give an analogy. Take an average liberal and an average conservative. Now, they would hold profoundly different opinions about Bill Clinton as a man, and what sort of job he did. But they would agree that he was President of the United States from 1993 to 2001.
