That's not what the verse says.
The verse says Paul did preach the gospel to the Jew first.
Paul also said he had to preach the gospel to the Jew first.
However, the Jews rejected it, so Paul then turned to preaching the gospel to the Gentiles.
(Acts 13:46) Then Paul and Barnabas answered them boldly: "We had to speak the word of God to you first. Since you reject it and do not consider yourselves worthy of eternal life, we now turn to the Gentiles.
This causes really big problems for your MAD because MAD claims a different gospel was preached to the Jews.
No. Only SOME MADs assert that was the case; though very few, in contrast to the many who do not. I don't.
As Paul's "to the Jew first" that he opens Romans with; he relates what he means by that in Romans 15. That that HAD been the order of his preaching in Acts.
While what he says in Acts 13 and Acts 18, etc., and also in Romans 1-3 and 9-11 tell the reader WHY he would go to the Jews first back when he was doing that.
Again, its like that article I posted about Preterism (which some on here right off concluded I might be promoting Preterism; talk about ignorance).
I posted it to show that all your ranting that MADs can't agree with one another leaves out the fact that neither do Preterists.
Again, MADs differ in their understanding about what Paul was doing when and where and or what he meant by one thing or another.
While some of the ones on here are nowhere near the level in understanding of their view as some of their other ones on here.
So please - quit lumping all MADs together - even those from within a same school.
Its your doing so that "is a mess."
