https://ehrmanblog.org/jesus-anger-mark-141-members/So far in this thread I have argued that Mark 1:41 originally said that Jesus got angry when the leper asked him to heal him; and I have shown that elsewhere in Mark’s Gospel Jesus gets angry in context involving healing. And so: if Jesus got angry when the leper asked for healing in Mark 1:41 – what exactly was he angry about? Over the years numerous interpretations have been proposed, and some of these explanations are highly creative.
Couchoud argued that Jesus is hungry in Mark because he has to be "like YHWH his Father".
So also for Bultmann the reason of the his being hungry is the following:
Couchoud, in the his last book, Le dieu Jésus (1951), accepted again the traditional thesis that Mark, and not Mcn, is the oldest gospel.
But the fact that Jesus is YHWH just in the his show of anger, makes me raise the suspicion that there is more than an interest, here.
The Gnostics pointed out just the anger of YHWH as the perfect proof of the his being an evil deity.
So "Mark'' (author), is replying directly against these Gnostics, by showing Jesus as hungry and full of anger, just in healing.
