I believe many Catholic dogmas regarding faith and morals are true (but some are stated weirdly or given wrong emphasis). Some examples typically rejected by Protestants ...
Sola Scriptura(scripture only) is an untrue doctrine just as the Catholic Church teaches. Here is the passage from the New Testament about the "private interpretation" of scripture — the context addresses the topic of false prophets and false teachers who improperly interpret scripture to derive or support their views. But the apostolic teaching must be our guide.
For we have not followed cunningly devised fables, when we made known unto you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty. For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased. And this voice which came from heaven we heard, when we were with him in the holy mount. We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: Knowing this first, that no prophecy of the scripture is of any private interpretation. For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost. But there were false prophets also among the people, even as there shall be false teachers among you, who privily shall bring in damnable heresies, even denying the Lord that bought them, and bring upon themselves swift destruction. (2 Peter 1:16-2:1)
