Well, if your theology is correct, then there was no great falling away that needed reformation in the 16th century, which is one reason for Trent.
Even where Rome had its own headquarters, at the time of the Reformation, the Catholic historian Paul Johnson described the existing social situation among the clergy:
Probably as many as half the men in orders had wives and families. Behind all the New Learning and the theological debates, clerical celibacy was, in its own way, the biggest single issue at the Reformation. It was a great social problem and, other factors being equal, it tended to tip the balance in favour of reform. As a rule, the only hope for a child of a priest was to go into the Church himself, thus unwillingly or with no great enthusiasm, taking vows which he might subsequently regret: the evil tended to perpetuate itself. (History of Christianity, pgs 269-270)
In the summer of 1536, Pope Paul III appointed Cardinals Contarini and Cafara and a commission to study church Reform. The report of this commission, the Consilium de emendanda ecclesiae, was completed in March 1537. The final paragraphs deal with the corruptions of Renaissance Rome itself:
the swarm of sordid and ignorant priests in the city, the harlots who are followed around by clerics and by the noble members of the cardinals households (A.G. Dickens, The Counter Reformation, pg. 100)
honest manners should flourish in this city and church, mother and teacher of other churches [yet] whores perambulate like matrons or ride on muleback, with whom noblemen, cardinals, and priests consort in broad daylight (cited in Denis R. Janz, A Reformation Reader, Primary Texts with Introductions, pg 406.
we have been given the benefit of hindsight that Christians living in the first 20 centuries did not have in looking at the Scriptures and seeing which way the wind is blowing. most Americans have been blinded by dispensational nonsense, so the Satanic deception is even stronger.
The Scriptures teach awaiting Christ's imminent return is to foster holiness, while the present declension is due to becoming more like the world, which Rome effectually fosters now. While when it had temporal power to exercise her claim to "coercive jurisdiction," she conformed to the world in using physical force, torture and murder, to deal with theological nonconformists. Which early Prots had to unlearn.
And it remains that while you want to selectively choose who is a a Catholic, those whom Rome treats as members testify that they are overall more liberal and less unified in conservative mortal views than those who most strongly hold to the supremacy of Scripture as the basically literal supreme authority, which is what RCs attack.
there certainly was a reformation needed, one of holiness and following the Apostolic Faith.
what wasn’t needed was the false teachers arising and teaching doctrines not found in the Scriptures and not believed by anyone up until that time.
