Yes, but it doesn't really help. He removed more conditions from the ritual law but he added conditions
to what Jesus taught, who had already loosed the yoke of the ritual law.
And Paul added a very divisive one at that. Based on something that he had (apparently) seen, namely the risen Christ . Others had no such advantage for "believing in one's heart that God raised him from the dead".
But no matter...add, subtract, the fact remains that Paul
changed the requirements of salvation from what Jesus taught. Jesus never seems to have taught the
requirement of believing that he will be resurrected as a condition for salvation.
Paul did.
So the question remains, who or what gave Paul the right? If Jesus had given Paul another set of keys to the Kingdom, I missed that part when I read the book of Acts.
