So, I want to convince you that:
A) if the epistle is genuine, then Carrier is right about ''brothers of the Lord''.
B) if the epistle is not authentic, then a historicist reading of ''brothers of the Lord'' is right.
Here I confess to base myself on an unproved premise, because I start from the assumption that Carrier is so honest to assume always as premise the exegesis of the consensus, or of a serious part of it even if a minority.So you quote the words of Richard Carrier “that this passage is out of place” and state this is the consensus view as if therefore I should accept this view just because it is the consensus, but I haven’t been convinced it is the consensus. Of course the consensus changes over time and I am most likely not aware of the state of the current consensus. Therefore I am saying – Convince me that the consensus is correct?
As his argument goes (from what I have understand) Dykstra is arguing something of very similar to your view: that everywhere, even in 1 Cor (and even in 1 Cor 9), Paul took advantage of the minimum casus belli (= a contingent dispute case), to make appear on the surface his own more general and sound contrast against high rank Christians (and hence against hypothetical biological 'brothers of Lord' where they appear in 1 Cor 9:5)
See the example of Dykstra:
What is making Dykstra in common with you? While you are projecting in 1 Corinthians 9 the same conflict between Paul and Pillars (a subset of all Christians) that is in evidence in Galatians, so Dykstra is projecting in 1 Corinthians 7 and in 1 Corinthians 9 the same conflict between Paul and pillars (a subset of all Christians) that is in evidence in Galatians.Another example [after a list of other cases that show a latent implicit conflict between Paul and Pillars] is in 1 Corinthians. In chapter 7 Paul praises his own ability to remain unmarried while allowing that marriage is acceptable for people who are ”unable to control themselves” (7:8-9); then just two chapters later he alludes to the married status of ”the brothers of the Lord [James] and Chepas [Peter]” (9:3-6). The effect, and quite possibly the intent, of these two passages is to portray in a negative light the men who opposed Paul in Jerusalem and Antioch.
(Tom Dykstra, Mark, Canonizer of Paul, OCABS Press, p.34-35)
To be honest, I would think naturally the same thing as you and Dykstra (beyond if the latter is right or wrong in this particular view) but ONLY under the pre-requisite that 1 Cor is an entire epistle and not, as argues Carrier, a ''mishmash of several letters''. I cannot verify at present if Carrier's position about its being a ''mishmash of several letters'' is right or not (I see that Robert Price says explicitly ''Chapter 9 is an interpolation'', The Amazing, p.334), but I can see that this is vital for Carrier's argument about ''brothers of Lord''.
If you assume that 1 Cor 9 is originally a distinct epistle, then the argument of Carrier is the following:
1) Paul is arguing about a particular set of rights and not only against those who have a wife (per se a subset of all the Christians); and those rights apply to all the Christians.
2) it is not possible to say a priori whether that particular dispute is for Paul merely a casus belli to reignite the more general debate between Paul and the Pillars (as described in Galatians) or a mere little quarrel of little value.
Therefore, Carrier continues, only the particular little quarrel (totally beyond if behind it lurks the dramatic ideological conflict of Galatians: we don't know) is in evidence.
To introduce reasons of wider controversy [the conflict of Galatians] behind this little potential casus belli [as we, me, you and Dykstra, are inclined naturally to do, but ONLY WHEN we consider the epistle as an entire] means to cut in half the number of chances in favor of the own thesis. It means reducing our chances by 50% while Carrier has his chances intact at 100%: and so we lose and Carrier wins.
Therefore, it implies that that casus belli is about a little conflictual difference of this kind:
Paul versus ALL the Christians.
if for no other reason that for the fact that the unique EVIDENT object of dispute is a set of rights (not only the single right ''to have a wife'', in itself a reason to engage only a subset of Christians, something that would go against Carrier's argument) that regard ALL the Christians.
Since Carrier is interested in an explanation as economical as possible, he find it in the opposition between Paul and ALL the Christians, so seeing in 1 Corinthians 9:5 a mere trivial crescendo of claims of kind ''If they can - which are mere Christians [=''brothers of Lord''] - why not me ?''.
Only in this way, he can accuse you (or Dykstra, or me) of introducing ''ad hoc'' hypotheses (the latent conflict of Galatians) behind an apparent small quarrel (the unique thing in evidence).
Once I recognize that Carrier is right in this case (but I repeat: I don't know precisely the precise reason for 1 Cor being a 'mismatch of >=2 epistles'', I see only that that premise is vital for Carrier), then I can answer to your next question:
No. I'm saying that if Paul’s letter was written AFTER 70 CE then I would agree ENTIRELY with you when you wrote, “that 1 Cor 9:1-5 presents the same picture of Paul as we see in Galatians”, because only in that scenario (the epistles as post-70 battleground between marcionites and proto-catholics) we MUST see behind even the more harmless, apparent ''quarrel'' (as is the case with 1 Corinthians 9:5) always and uniquely the same explicit dramatic pattern of Galatians, i.e. the mere pretext of the same more wide conflict that opposes the heretic pseudo-''Paul'' of Marcion to the catholic pseudo-''Paul'' of Acts.Are you saying that if Paul’s letter was written before 70 CE then you would agree with me when I wrote, “that 1 Cor 9:1-5 presents the same picture of Paul as we see in Galatians”?
Therefore we are in this paradoxical case:
if the epistle is BEFORE 70 CE, then 1 Cor9:5 describes only an apparent little harmless quarrel between Paul and abstract ALL the Christians, therefore ''brothers of Lord'' means ''generic Christians''.
if the epistle is AFTER 70 CE, then nothing, very nothing!, prevents us, nor Carrier!, to see behind the slightest pretext really the casus belli for the conflict -- again in all its dramatic virulence -- between the Paul of Marcion and the Catholic Pillars & ''brothers of Lord'' (that therefore become the biological ''brothers of Lord'').
I hope this time I am more clear.
