You've said PLENTY to indicate that Scripture is somehow lacking without 'tradition'.
Scripture is only “Lacking” when interpreted by folks without the inspiration of the Holy Spirit, guided more by their ego.
Can’t you see the results of that? Too many people thinking they have the gift, and coming up with interpretations that would make the Holy Spirit a schizophrenic or a liar. Two contradictory interpretations of Scripture cannot both be true
The Universal Church has never changed it’s doctrine in two millennia. Things have been clarified as needed over time.
