To have Paul teach people that Christ saves is like using Hitler to teach arithmetic. Anyone can teach arithmetic, but having Hitler do it gets the kids worshipping Hitler, so he can promote genocide.

Paul says nothing significant about Christ or morality that any idiot doesn't already know. By having Paul present it, he can include the pagan religion of sacrifice.

The pagan religion of sacrifice is as destructive as Hitler's genocide. It coerces people into doing immoral acts to get favoritism from satan.

Paul replaced Christ's religion based on morality with the religion of the demons based on sacrifice.

Sacrifice is how the demons controlled humans for thousands of years before God created his religion. The demons required people to murder their children on an altar as a test of allegiance. Only the most deranged psychopaths require murder as a test of allegiance. Paul placed God in the same category by saying Christ's crucifixion was a sacrifice which pleased God.

God spent two thousand years prior to Christ's time teaching the Jews what is wrong about the religion of the demons and how to replace it with a religion based on morality. Paul then reversed everything being taught by God and claimed that sacrifice is the only purpose of God's religion.

Sacrifice is sin, not virtue. If a little bit of destroying can be rationalized for a supposed good, then any amount of destroying can be rationalized, and all sin follows. Christ said sacrificing is not what God wants (Mat 9:13, 12:7).
