You've got to remember that what we're dealing with is a fantasy narrative that says Jesus, being the only-begotten son of God, is incapable of sin. It also says he was executed and three days later came back to life. And that he could walk on the surface of water without sinking. Does any modern person believe any of this? I don't. I think Jesus was a very enlightened prophet and spiritual teacher, which is what the official doctrine of Islam says about him, but he was a human being. Why would he be incapable of sin? When Jesus drove the money lenders out of the outer court of the Temple, he was angry, right? Where was "turn the other cheek" that day? When he stole produce out of a farmer's field that Jews were forbidden by Jewish law to eat on that day, and ate the produce, was that being without sin? How about when he interfered with a legal execution? Was that sin, or just a violation of the law? Jesus was a human being, subject to all the failings of all human beings, so *of course he sinned*. Of course he did. He also made mistakes.
