Why did the early Christians begin worshipping separately from the Jews who did not believe Jesus was the Messiah?

The movement that originated around Jesus must have suffered a traumatic setback with his death. Not so much that a Messiah couldn't die, but that nothing happened. The kingdom didn't arrive immediately as they might have expected. For a while we don't know what happened to the followers of Jesus. They apparently scattered, but not too long thereafter it seems that they came to the conviction that something had happened. Something that did change their perspective on who Jesus was and what he would mean for the future of the movement, and this is what we know as the resurrection. Now it's not clear what happened in the resurrection. We don't know exactly how it occurred but what we do know that the followers of Jesus were absolutely convinced that he had been raised from the dead and had been taken away into heaven as a vindication of his messianic identity. He was the crucified and risen Lord ... The resurrection story brings a different perspective to the understanding of Jesus. If he thought of himself as a prophet, as a messenger of God, that changes when he himself is raised by God from the dead. He is now someone vindicated, and it's really the belief in the resurrection experience that leads the disciples to come to think of Jesus as somehow more than just a prophet. As the Messiah himself. He is the one who has been vindicated by God by being exalted into heaven as son of God.
