Many have taught how about how Paul seems to contradict himself let alone Jesus, James, John etc... Is the reason we MUST have Paul agree due a possible error of inerrant view of what many believe is the "canon" of scripture. Many scholars point out that the early church(patristic) really did not teach what many would consider Paulinist doctrine. Faith "alone" was clearly not a normal teaching and clearly lacked the emphasis that many have today. Marcion who was a strict Paulinist clearly was an outsider. I am not saying Paul has not value or anything but the possible overuling "all must agree" to make things fit when they don't.
Yet many get confused on "works" "law" "endurance salvation" which are clearly taught by Jesus, James, John etc... While limited in part in Pauls' teaching which many would point to his inconsistency. What if Paul has been compromised by Marcion followers who elevated Pauls writings? What if they simply don't agree nor did in many areas.
We see Paul being cast out in Asia
2Ti 1:15 This thou knowest, that all they which are in Asia be turned away from me; of whom are Phygellus and Hermogenes.
yet and Jesus confims in
Rev 2 the Ephesus did the right thing in get rid of those whom called themselves apostles. Yet we see Paul doing the very thing defending himself in his letter that he is an apostle. Just some thoughts on why we see such disagreement or contradictions yet many throw a possible blind eye to some areas of possible doctrinal inconsistency for the sake of "unity of scripture". Just some food for thought!
