Price argues that there is a group called brothers of the Lord? I doubt it.
He argues that that it refers to a "missionary brotherhood"
p. 65
It's unlikely that Paul is referring to Jesus' brother.
Only, that's exactly what he says.
Paul met apostles James, Peter, and John, no doubt the same James, Peter, and John that are recast as disciples in gmark.
Again, there are two different James. We know this because one dies in Acts, and yet James is still mentioned. Likewise, Mark refers to the disciple James, and also lists James among Jesus' brothers (as does Matthew). Again, different James.
It's foolish to suggest that the James referred to in Acts is Jesus' brother because it doesn't say that he isn't.
You keep attempting to divert the argument. It doesn't matter whether or not the two James' in Acts are completely fictionary. What matters is how Paul, Josephus, and Mark/Matthew refer to James, Jesus' brother. We don't need Luke/Acts. Unless Luke/Acts specifically states James is NOT Jesus' brother, than your argument is simply one from silence, whereas I have three independent sources.
Your argument certainly is:
1. Paul mentions James, Jesus' brother, whom he met.
2. When they list Jesus' brothers, Mark and Matthew both list James.
3. Josephus tells us James is his brother.
Now, to argue against all that, you argue:
1. Paul is being metaphorical, although you can't explain the syntax, nor is there any indication he is.
2. Your contradictions in your analysis of Josephus were pointed out above.
3. Luke/Acts never mentions Jesus had a brother James. Of course, he doesn't say Jesus didn't have a brother James, and three other sources say he did.
[1Cor 9:5] Do we not have the right to be accompanied by a wife, as the other apostles and the brothers of the Lord and Cephas?
But then again, there is a group referred to here as the brothers of the Lord, not necessarily a designated name of a group, but the reference does appear to be directed towards a brotherhood of believers
Exactly. Why do you think you have apostles on the one hand, and Jesus' actual brothers on the other? Mark/Matthew make clear that Jesus had more than one brother (as would be natural). If this was supportive of your "metaphorical" reading, "directed towards a brotherhood of believers," why seperate them from the apostles, who WERE the brotherhood of believers.
Your case amounts to a strained hypothesis that "brother of the lord is metaphorical." There is no evidence of this, as we have nowhere a clear example of metaphorical use of this syntax, particularly when it is kin identification.
Furthermore, two OTHER sources confirm Paul.
