I’ve never understood the kind of “Christianity” that sets Paul up in opposition to Jesus and Jesus’ teaching in the Gospels. Neither would Paul.
Jesus was not teaching “Christians”, was he? He was sent “only to the lost sheep of the nation of Israel” (Matthew 15:24). It was Paul whom Jesus called to go to the Gentiles, remember? We were “without hope and without God in the world” before that.
If you listen to the one Jesus sent for you, there is no opposition because you aren’t trying to steal stuff from Israel things but instead getting the things He has for YOU.
These things are heavenly, spiritual and not earthbound. Like I said, Paul will blow up your Labyrinth REAL good. This is why you find Catholics ignoring him in favor of Jesus speaking to THE JEWS, and then trying to put teaching given to those UNDER THE LAW on Gentile, post-Resurrection believers who are NOT UNDER LAW BUT UNDER GRACE.
It doesn’t work...without the smoke, mirrors and sticky tape of Rome.
