I think plaigerists have put words in Paul's mouth.
Well,...I'm not sure how much of Paul's letters have been tampered with, among the earlierst manuscripts, or what varaiations exist among the extant manuscripts. On that count, we could also be suspicious of Jesus teachings too, who could know? (beyond scholarly research and one's own spiritual discernment). - I find Marcion's early involvement and emphasis on Paul's eaching most interesting, as he also had a select version of Luke's gospel,...did he do any tampering to the texts, as the pioneer of the Christian canon? - lots to consider....
