I'll help, maybe: Jesus didn't talk about who is a Christian. He was looking for followers.
Still is.
As a non-Christian, and therefore an outsider looking in, I'm mystified by this debate that pops up from time to time about whether Mormons are Christians. They recognize the divinity of Jesus Christ. What other qualification could there be?
Well, far be it from me to tell Christians who's a Christian. I'm just puzzled.
