The Importance of Establishing the Data to Be Explained

The postmortem appearances of Jesus are attested, as you say, in this extremely early tradition that Paul quotes in 1 Corinthians 15. Even Mark knows of them, but simply foreshadows them and doesn't narrate them. So again, you're back to whether or not these can be plausibly explained on the basis of psychological phenomena like hallucinations,. But it's pretty difficult to deny that they occurred. And so Alex, I'm not kidding. I can't think of any historical Jesus scholar who denies that the original disciples had these postmortem appearances."
