Why do you bring that ''typology fulfillment'? How can you deduct that typology fulfillment was involved?I"m baffled by this. Bernard, surely you know of the phrase 'typology fulfillment'? Of course it couldn't have been the same person, just as many of the prophecies were fulfilled in history long before Christianity came along, but that didn't keep the creative and desperate Jews from seeing a DEEPER and more complete FUTURE fulfillment since obviously the promised peace had NOT been fulfilled. Clearly early Christians did this, as they do today. As such this Jesus, son of Josedec could well have been seen as a 'type of' Messiah also named Jesus to come later. Again, 1 out of 25 males in 0AD were named Jesus according to the source I gave so we can't just excuse or reason it away too easily IMO.
The rest of your post is just unevidenced supposition with very little possibility to be true.
Certainly we do not know about "creative and desperate Jews from seeing a DEEPER and more complete FUTURE fulfillment" assigning the name "Jesus" to their expected Messiah because of what they read in Philo's works.
Did you also turn up to be a Mythicist?
The coincidence can be very well explained: the high priest from the return of the first exile up to, at least, the rebuilding of the temple, was named Jesus son of Josedec. The man credited to have started Christianity was name also Jesus (of Nazareth OR son of Joseph). It happens the two first names are the same, but the name is not rare among Jews of these times. If you want to make a case about that, so be it.
Other mythicists made cases about the Christian Jesus being copied in part from another Jesus, such as Jesus the rustic would-be prophet in Jerusalem (ref: Carrier's OHJ) or another Jesus, one of the last temple high priests.
Actually, Christians made a lot of out-of-context &/or cut-and-paste quotes from the OT. This is undeniable. But not to the extent as for the Jesus from Zechariah associated with the strictly incorporeal heavenly being of Philo.Clearly early Christians did this, as they do today.
And the first known one to have made the dubious connection is not a Christian, but a Mythicist: Carrier.
It seems that Mythicists are more desperate than Christians when finding evidence to support their beliefs.
Cordially, Bernard
