And by this method (denial) folks, the RCC can get away with anything they say.<quoted text>
Yeah. You knew about the Latin. Didn't know the context in which the phrase was said, but you knew the Latin thing.
You've pasted the same Ferraris quotes as you had previously. Ferraris WAS a canonist, no question. His work, still, doesn't constitute Catholic doctrine. Were he alive today, he'd tell you as much.
Unlike Protestantism, everything a Catholic writes concerning theological matters isn't awarded doctrinal status just because it's written down.
Why being a canonist is he therefore invalid?
An eighteenth-century canonist of the Franciscan Order. The exact dates of his birth and death are unknown, but he was born at Solero, near Alessandria in Northern Italy. He was also professor, provincial of his order, and consultor of the Holy Office. It would seem he died before 1763. He is the author of the "Prompta Bibliotheca canonica, juridica, moralis, theologica, necnon ascetica, polemica, rubricistica, historica", a veritable encyclopedia of religious knowledge.
