But Josephus is not ... and that is the point. One can (relatively) easily justify the early Christians using such language to refer to something other than a biological brother, but not so in the case of Josephus, who's reference is clearly problematic.
No more problematic than the Gospels, I think. Matthew 13 (and the similar passage in Mark 6) record that it's the people of Jesus' hometown and not his disciples that declare that he's the brother of James (and Joseph, Simon, Judas, and an indeterminate number of sisters):
53When Jesus had finished these parables, he moved on from there. 54Coming to his hometown, he began teaching the people in their synagogue, and they were amazed. "Where did this man get this wisdom and these miraculous powers?" they asked. 55"Isn't this the carpenter's son? Isn't his mother's name Mary, and aren't his brothers James, Joseph, Simon and Judas? 56Aren't all his sisters with us? Where then did this man get all these things?" 57And they took offense at him.
Josephus is "outside the movement", but if you believe Matthew and Mark, the townspeople who declared that James was the brother of Jesus were "outside the movement" as well.
Again, if Eusebius was so willing to engage in the most sloppy and transparent 'pious fraud' it is unclear why he would have allowed the James formulation to stand.
But here's the thing: if the
Testimonium is really "most sloppy and transparent
'pious fraud' ", then one of two things occurred:
- Eusebius fabricated it.
- Someone else fabricated it, Eusebius recognized it as a fraud and passed it along anyhow.
If it really is obvious that the
Testimonium was a fraud, then Eusebius was guilty of deceit whether he wrote it himself or not.
There is simply no basis for insisting the Eusebius fabricated all or part of TF. It is simply a piece of speculation engineered to prop up a set of mythicist presuppositions.
And I think I've mentioned before that I have no particular evidence pointing to Eusebius specifically. For me, the matter's more that the
Testimonium wasn't there when Origen had
Antiquities but was there when Eusebius had it. This means that it was changed by someone after Origen but before Eusebius published his
Demonstratio Evangelica. One of the people who was in a position to make this change was Eusebius and while I don't exclude him from suspicion, I also don't think he was the only person who could've made the change.
