James, the brother of Jesus said, “pure religion is to take care of orphans and widows and keep oneself unstained by the world”. So I think he, and many of us Christians would largely agree with you. Humans muddy things up, and that is why Jesus preached to the choir so much.

I would personally be very careful to throw the baby out with the bath water though. If Jesus actually lived, predicted his death and resurrection, and rose three days later, there is good reason to be a Christian in its basic sense, even if one doesn’t agree with some or many of the modern, human deviations from what Christ taught.
