Look, there's long been a debate within MAD called 12 In or Out [of the Body of Christ]. I've never taken a side because I've never seen the need. Paul is the apostle God sent to Gentiles, and the 12 agreed to that. His doctrine, as Christ revealed it to him, is my doctrine. Paul's gospel is the ONLY gospel that saves today and it is NOT the gospel of the Kingdom, WHICH KEYED ON NATIONAL COVENANT ISRAEL REPENTING AND SERVING CHRIST. I'm not going to bother explaining the difference because you've heard it all before and you don't care.
But the fact remains INDISPUTABLE that if we want doctrine from Christ, we HAVE to get it from Paul because Paul wrote DIRECTLY to the Body of Christ. Paul's gospel has NOTHING to do with Israel. It is IN SPITE of Israel. It is not to Jews first -- it is to Jews and Gentiles WITHOUT DISTINCTION. The gospel of the Kingdom was NOT without that distinction -- it was to the Jew FIRST.
Paul was given to write to and for us.
Read Peter, James and John to see who THEY were told to write to. It isn't us.
