If he rose from the dead, doesn't that help to back up his claim of being the son of God?
If he had risen from the dead, then yes, I'd believe he was the son of God. He didn't.
It's what scholarship says.
It's what some people have said. Not all of them. And even if they all did (they didn't) it wouldn't be a fact.
Thomas didn't believe it did he? Presumably so scholars agree that Thomas didn't believe it?
