I think he was indicating that a sermon should be longer. Technically a “homily” is a commentary on a Biblical Text… but that doesn’t mean it has to be short.
From the TPM prime discussion (sub only):
Aslan on literalism:
Two TPM members had overlapping questions, so I’ll report them both, along with Professor Aslan’s answers:
My question has to do with archaeology, though. You seem to take for granted that Jesus was a real human being. I guess I’m not real familiar with the evidence, but how do we know Jesus was a real man? Are there records of him made during his lifetime, or is it all of religious texts?
Thanks for dropping by Professor Aslan.
In your view, did Jesus believe he was the Messiah? And, if so, did he also believe he was the Only Son of God in a literal, non-honorific sense?
Also, did Jesus really believe the world was about to end (as many of his recorded statements say or imply)?
My personal take is that these sorts of answers can’t be recovered from the primary source material. I have a rough understanding of Paul’s point of view and Christ is a knowable character. I’m not so sure about the historical Jesus.
