Scott,
I tried to address that issue in post #2. I think that the lengthy article offered in post #3 goes into detail on this. If the Spirit brought back to Paul's mind a teaching he heard directly from Jesus,or if he spoke on his own apostolic authority it was still binding as the word of God.
It is not like a red letter bible has the words of God in red, but the ones in the black print are optional. Take a stand with the person you are speaking withand pray that The Spirit will give him a heart to receive the truth,rather than to continue to oppose himself

23But foolish and unlearned questions avoid, knowing that they do gender strifes.

24And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient,

25In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth;

26And that they may recover themselves out of the snare of the devil, who are taken captive by him at his will.
