But there are other alternatives:
- The experience of Christian proselites, who abandoned their own families to follow Jesus.
I think that Jean Magne is correct about this point:
- A Gnostic tradition had Sabaoth rebel against Yaldabaoth: this rebellion against his divine father was given as example of the Gnostic rejection of the carnal world and anything in it.
Only that this Gnostic kosmophoby is judaized in Mark: Jesus rejects his family, but his family is an exemplar Jewish family, with a lot of brothers and sisters.
The young rich is reluctant to abandon his property, but he becomes allegory of old Israel, reluctant to open himself to gentiles.
The Gnostic "division" between the spiritual and the carnal world becomes the "sword" brandished by the apocalypticist Judaized Jesus.
The accusation of bastardry against Jesus ("is not this the son of Mary?") judaizes the Gnostic rejection felt by the Gnostics against themselves as creatures of the "bastard" demiurge.
This last accusation became "euhemerized" with the Celsus's accusation against Jesus "son of Panthera": the demiurge was entirely theriomorphic and therefore he was pan-thērion: having completely form of animal.
Hence Jesus was despised as son of Mary and of the demiurge. The demiurge was the original "carpenter".
But all was judaized and sanitized in Mark.
