I cringe every time I hear you say Paul came with a different gospel. Jesus came with another covenant and he, only he could. Jesus is the Sacrificial LAMB OF GOD ONCE AND FOR ALL, but you have Paul coming with another gospel, just because you say so. Unbelievable.
Question for you, GT:
Why did Paul say, "Imitate me, as I imitate Christ? Why not just cut out the middleman and say "imitate Christ?"
It's because Paul's message was COMPLETELY DIFFERENT than what Jesus taught.
Jesus followed the law, from when He was circumcised at 8 days old, to when He died on the cross.
Yet Paul said if you keep the law, you're cursed, and Paul never told his converts to circumcise, let alone keep any other law. In fact, he said if you keep one law, you are a debtor to keep the whole law.
And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law. - Galatians 5:3

James said if you break one law, you are guilty of breaking all of them.
If you really fulfill the royal law according to the Scripture, “You shall love your neighbor as yourself,” you do well;but if you show partiality, you commit sin, and are convicted by the law as transgressors.For whoever shall keep the whole law, and yet stumble in one point, he is guilty of all. - James 2:8-10

This is why Christians should not keep the law, not only because we are delivered from the law (Romans 7:6) through Christ, but because if we keep one law, we must keep them all, and if we break one, we are guilty of breaking them all.
Paul said "imitate me as I imitate Christ" because his message was different than the rest of the New Testament, because imitating Peter and the other Apostles would end up circumcised and keeping the law.
No one other than Paul says "imitate me," not Moses, not Abraham, not Isaiah, none of the Old Testament prophets, not Peter, not James, not John, not even Jude. ONLY PAUL. Paul taught do not keep the law. If his message was the same as the rest of the New Testament, then why is he the only one who says that? Not one other Apostle or author wrote "do not keep the law." They all said "keep the law."
