True...but that is not what the catholic church teaches their followers...so it falls on deaf ears unfortunately....they really don't know the truth of the history of the church....they eliminate anything which doesn't align with their false historical teachings...and as much what they fully eliminate from those teachings.
Maybe the point of biggest difference is the Roman Catholic official idea of communion (Mass). That the Lord does not just manifest His presence there but somehow manages to swap out a physical thing for a supernatural thing, but in a way that no eye can detect.
As a mature Protestant who has taken the communion with a marked sense of the Lord’s presence, I believe the Catholic transubstantiation doctrine to be wrong and confused, but that it does not negate the primary use of the communion. It is a place to meet with the Lord in spiritual remembrance. And an acute sense of that in Catholic Masses doesn’t require the transubstantiation theory to account for it. He might appear more strongly there, in fact, in order to offset any sense of idolatry. To demonstrate tangibly that He is not confined to that wafer or to that wine, but radiates outward into a Christian’s life from the place where He is met. He does omnipresence well.
Christ said it best when He was on the donkey entering Jerusalem. The Priest and officials of the Temple told him to tell his followers not to praise him "If they kept quiet, even the stones would burst into cheers."
GOD's Word was written for mans sake and GOD certainly has the power to teach it to any believer whether it is in text or by works of The Holy Spirit. If every written Bible were burned today GOD's Word will survive and still be taught to man.
There is no perfect church overseen by man. All have their faults. There is no official Church but the blood bought believers and followers of Jesus Christ whom He calls to be His own. We do not have that authority to declare who is and is not included whom Christ calls in that respect. None of us do.
We have many different churches where GOD's Word is preached but Jesus Christ is the sole head of it. Put a dozen Math teachers in a room to do Algebra and you'd likely get a dozen different methods but the same answer and results. Put thousands of Christ centered churches into action and the same thing you will get the same end result despite differing methods of how they got there. They may disagree on theory/theology but serve the same GOD and belong to the same Jesus Christ.
Jealousy has been used several times in The Bible by GOD to produce desired results :>}
