He did not say to discount the bread of “other groups”, much less the very disciples who had come to hear him.

Read the passage, he does.

Neither does he resolve the problem with a miracle in this chapter. He simply extols his apostles to understand the lessons of the Sermon on the Mount.

What verse says that? Btw, as I am sure you are aware this story is in Mark and the Sermon on the Mount was in Matthew, not in Mark. You totally knew that and you must have forgotten for a second, I am sure.

If the lesson was that Jesus is Magical, it wouldn’t have been this plea to remember the prior events. He would have simply magicked up some bread.

Assertion not fact.

No, this is a plea towards self-reliance. Don’t trust the patronage of these rival church groups. Don’t trust the patronage of a hostile government. You must feed yourselves.

It doesn’t say that. That is what you are putting on it.

So then how does this refute the claim that The Sermon On The Mount occurred?

Didn’t say it did. Well not directly at least. You brought up the loaf and bread miracle (must have forgotten for a moment it happened twice, I am sure) and I discussed it. As a scholar such as yourself knows it is an example of a Mark sandwich story which is the author’s attempt to deal with competing oral narratives, but whatever. The point is we can tell the author was willing to lie about small things for this passage which puts in doubt other authors who used him as a source, like Matthew. Short answer no that story doesn’t disprove that speech but it does cast doubt on how honest people were being.

You know the 3 miracles are just recycled Elisha and Elijiah food multiplication miracles and the Jesus rebuking them was just Mark trying to talk smack about James+Cephus.
