There's lots of disagreement among Catholics on their false doctrines.
They've also made a mockery of the finished work of Christ with the office of priest which isn't biblical. Also this apostate entity invented the sinlessness of Mary, Co-Redemptrix and Co-Mediatrix. Not to mention being laden with idolatry.
As for protestants, they mostly agree on the essentials of the faith. Some of these have abandoned the faith, and the authority of Scripture and are apostate just like the RCC. WoF, Prosperity Gospel churches, Sodomite churches &c are not genuine churches.
