“or, get this, the Holy Spirit cannot guide the Magisterium, but ‘indwells” in every milkmaid and farmhand...LOL”
I’d put it thus: “The Holy Spirit is alive and well, but He doesn’t contradict what he said earlier to the Apostles. Scripture “is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, 17 so that the servant of God may be thoroughly equipped for every good work.”
So if something goes beyond scripture, it may not be false, but neither is it needed to equip the servant of God for every good work!
You won't get this Catholic to deny the divine nature of the letters to Timothy, but how do you reconcile that, at the time it was written, the New Testament did not yet exist nor was there an Old Testament canon universally agreed upon by all Jews? Further, how do you reconcile it against itself which was a teaching based upon tradition?
