I would have to say that Paul's reference to James as, "the Lord's brother" (Gal. 1:19), is a clear indication that Jesus was a real person. However, since nothing in the gospels is really historical, and since Paul's Christ Jesus seems to be based far more on his direct revelation (a.k.a. hallucination) than upon anything he learned of any historical Jesus, even a real, historical Jesus remains more a mythic construct than a real person.
That’s certainly the obvious example to raise. And I did wonder why
Eight_Bits had not raised it in any direct way before (perhaps he will tell us). And as I noted above (and in the parent threads), Bart Ehrman and other bible scholars do of course give that as something they believe to be direct and quite certain evidence of Jesus.
However, that particular sentence has of course been well known for 2000 years. And sceptical authors have been writing to say they doubt that as evidence for at least the last century or so. So obviously they don’t think that sentence can be taken at face value as evidence of Jesus.
In the parent threads to this one we have discussed in some detail the sort of reasons given by those sceptical authors. Those reasons inc such things as -
1. According to Alvar Ellegard - that seems be the one and only such reference in any of Paul’s letters.
2. That reference is very brief, consisting of only 3 to 5 words, ie saying
“ … other apostles saw I none, save James, the lords brother”.
3. Ellegard says (I assume he is correct) that Paul more often uses the words brother, brothers and brethren to mean brother in belief, not family members.
4. Those 3 words or 5 words, ie “save James … the lords brother”, come at the end of an otherwise competed sentence. They are presented in the form of an afterthought as if added to the end of an already completed sentence, viz. “
other apostles saw I none“. ……oh, except for James ……oh, and I should add that he was the “lords brother”.
5. It would obviously have been extremely easy for any later Christian copyist to add either the 3 words or all 5 words to the end of a sentence like that.
6. The reasons why Christian copyists did things like that are well known. They were not necessarily deliberately lying, deliberately trying to invent things, or trying to mislead people. They simply added or changed a few words here and there, wherever they later came to believe that certain information should be added, deleted, or otherwise “corrected”. And they seem to have done that quite regularly in both the OT and NT.
7. There are apparently numerous examples where scholars now agree that biblical texts have been altered in that way. In the YouTube film, John Huddleston says about the OT (he was being asked about the OT at that point) that when the OT was being written, it was really written as theology rather than as the history it appears to be. He says, it was very common for later copyists simply to delete older passages which were no longer in current belief, eg because the prophecies had not been realised, and to just add a new or altered prophecy or story in its place. That is - the OT was a theological work in progress and subject to constant change.
8. There are in the biblical writing several different people named James. So it is not necessarily clear that Paul is talking about the same “James” that later writers and copyists believed to be the actual brother of Jesus.
9. Paul does not tell us how or why he thought this particular “James” was the “Lords brother”. If this “James” or anyone else had told Paul that he was actually the brother of Jesus, then we know nothing of any such conversation from Paul’s letter. In fact there is nothing at all in Paul’s letter to show that he had any conversation with James or the others on that occasion (or on any other occasion) about Jesus. Nothing is said there at all about Jesus by any of them.
10. Again as Ellegard points out - that is very curious (ie their apparent silence about Jesus), because only three years before that meeting Paul’s entire life was supposedly changed by his sudden conversion to belief in Jesus, and yet when he writes of meeting the actual brother of Jesus, he (Paul) never mentions asking the brother a single thing about Jesus. Paul has just met the actual brother of the Son of Yahweh himself, he is discussion with that brother specifically about their religious beliefs, and yet he does not mention ever asking about, or being told, a single thing about Jesus??
11. This same “James” apparently wrote his own surviving gospel. But nowhere in that gospel does this James ever claim to have been the actual brother of Jesus.
12. We do not of course have anything actually written by Paul c.50AD. The letters we have come from later Christian copyists. The earliest copy of which appears to be the so-called Papyrus P-46, which is thought by most biblical scholars to date from around 200AD, though one scholar apparently thinks it might be much earlier than 200AD, and number think it is likely to be a fair bit later that 200AD. So, strictly speaking we do not know if Paul every wrote any part of that passage.
13. Even today many Christians and Muslims still refer to fellow believers as “brother” or “sister”. They may talk in general of going to meet their brothers (plural) or meeting a particular brother or sister (singular). They don’t mean that any of these people are actually family members.
