Why didn't you answer my question?
What gospel did Paul preach to those in the synagogues?
Surely he did not preach the gospel of the uncircumcision then, did he?
I did answer it; in my reply to DamP.
Which you both failed to see.
I based my answer to him on the following.
Unbelieving Israel was found having continued in Uncircumcision by the Law in Acts 7:51-53.
They were now no better off than lost Gentules, or heathen; as far as being nigh unto God was now concerned, Rom. 3:9-10; Rom. 3:19-20.
Romans 2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Or as Paul later reminded the Thessalonians "the wrath is come upon them to the uttermost" - for their having "filled up their sin," which they now continued to fill up, in their opposition of Paul's ministry, 1 Thess. 2: 16.
In short, I hold the view held by a huge majority of Pastor-Teachers within Mid-Acts - that Paul had preached one gospel to all, without distinction.
That aspect of the gospel of Christ to the Uncircumcision (lost Jew and Gentile); which is basically the issue of the Grace of God in His Son to all, but upon all that believe, absent of the Circumcision/ Uncircumcision distinction "for there is no difference; for all have sinned, and come short of the glory of God" Rom. 3:21-31.
Paul himself was saved after he was concluded in spiritual Uncircumcision with his nation.
