That’s an NPC argument. Stop puppeting the talking points.
Catholics didn’t even have a canon until after Luther. You can’t whine that he changed the Bible when Rome didn’t even have a list of official and inarguable books until after Luther died.
Actually you are wrong — I would suggest some reading the Council of hippo as well as the council of Trent — the Council of Trent just made dogmatic articulations about why the Church had the same canon for 1200 years prior to Luther’s questioning.
