People who believe in your god and the divinity of a certain Palestinian Jew are Christian, in my humble opinion, regardless of their thoughts on certain books in the Bible (which was written, selected and translated by humans, regardless of where the original story came from)
Jesus was not Palestinian, he was Judean. If you were to go back and ask him, he would have been confused at the term, which wasn’t used for another century when Hadrian wanted to remove Jewish links to the area.
