“Jesus answered, Thou sayest that I am a king: to this end was I born, and for this end came I into the world; and for this purpose I came, that I should bear witness to the truth; and everyone who is of the truth, heareth my voice” from The Gospel of Nicodemus, also called The Acts of Pontius Pilate
So the purpose of Jesus was to teach the truth and not to die for our sins. You wouldn’t know that from most modern Christian churches who seem to teach that the only reason for Jesus to be here was to die as a sacrifice for us. What a really strange and barbaric concept! If Christ came to Earth just to die here, why bother at all?
No, Christ, as Jesus, came to teach the truth. But why would that be necessary if the priests at the temple were already doing that? The obvious answer, is that they were not teaching the truth, especially after the Romans took over the land and made the priests teach what they wished them to teach.
Also, if Jesus came to teach the truth, then the scriptures being used by the Jews at that time were not completely true, or at least the interpretation of them wasn’t. And yet, in most Christian churches, those old testament books that Jesus came to correct are now part of their Christian Bible. Why? Do they think Jesus was lying when he said the priests of the temple were teaching falsehoods?
If you read the books of the old testament, you will see that the God of the old testament, or most of it anyway, was an angry god, a violent god, a vengeful god, a jealous god (how could the real God possibly be jealous of anyone?). But in the new testament, Jesus speaks of a loving Father in heaven, a tolerant and forgiving Father, a God that is so much different from the old testament that it is like Jeckle and Hyde. Obviously, they are not the same.
