“...... even if there genuinely were 30,000 Protestant denominations, one thing all Protestant denominations agree on is that the Roman Catholic Church is not the one true church of God. Protestant denominations are unanimous in rejecting the papacy, the supremacy of Rome, prayer to saints/Mary, worship of saints/Mary, transubstantiation, purgatory, and most other Roman Catholic dogmas. Sola Scriptura has led all Protestant denominations to the same conclusion – the Bible does not teach many of the things Roman Catholics practice/believe. Further, outside of disagreeing with Roman Catholicism, the Protestant denominations agree on far more issues than they disagree. Most of the Protestant denominations were formed because of a non-essential doctrine, a side-issue, on which Christians can agree to disagree.

“worship of saints/Mary”
i am sure you can point to the Roman dogma that backs this up?
if not, i am sure you will retract, correct?
why do Protestants have 27 books in their NT? what human authority or institution is there that can say infallibly this is the correct canon?
if there isn’t one, what assurance do you have that what you claim is the sole authority for your doctrines, is complete and correct?
