The central claim of the New Testament is that Jesus is not simply one teacher among many, one more in a long line of prophets, but rather the word made flesh, the incarnation of the divine word which made and sustains the world. Therefore, what Jesus says, is. To the dead daughter of Jairus, Jesus said, Little girl, get up, and the dead girl got up. At the tomb of Lazarus, Jesus shouted, Lazarus come out! and the dead man came out. The night before he died, Jesus sat down with his disciples for a Passover supper. He took the ordinary unleavened bread, broke it, gave it to his disciples and said, take this all of you and eat it; this is my body. He then took the blessing cup after supper and, passing it around, he said, take this all of you and drink from it; this is the cup of my blood. Was he trading in symbolic and metaphorical speech? If he were an ordinary human being, one more prophet or religious poet, thats all he could have been doing. But he was, in fact, the Word of God, and therefore, his words had a power to transform at the most fundamental level of reality. This is why that ordinary bread and wine became Christs very body and blood.

So, before He was (allegedly) "incarnated," G-d was not always truthful? He was capable of untruth until He (chas vechalilah!) became a human being?
His dictated words to Moses were not necessarily true because . . . why? He was lacking in some perfection of some sort?
