Well, yes, since the Holy Spirit made him the chief writer of the NT, and as these are the only wholly inspired transcendent and substantial records of what he preached, it is these that must judge all that is attributed to him.
To hold that what Rome says he or anyone else said via her amorphous "oral tradition" is the infallible word of God rests upon her novel and unScriptural premise of ensured perpetual magisterial. And what Rome claims to infallibly declare certainly is not wholly inspired of God.
LOL, you just pulled an oral tradition of your own straight out of your...hat.
Just shut your eyes and put your fingers in your ears, shouting LALALA as loud as you can.
