If there was anything I would have liked to have added, that might be the consideration that whereas Thomas Jefferson (and many others) certainly had a point historically in fingering Paul as having distorted the teachings of Jesus, Jesus does not take any issue with Paul, just as much as he does not take issue with Judas, because his teaching is forgiveness, not judgment. In the Course, Jesus corrects many Christian theological terms and notions and clarify what the original meaning of his teachings was, and at times he even quotes from Paul's work where he does offer more right-minded statements.
