Oh how non-Catholics love to use that verse to try to say that by word means by our epistle.
Relying on the RCC for the truth of scripture is like relying on progressives for the truth of history.
Backed up by scripture my Friend.
Acts 17:11 Now the Bereans were of more noble character than the Thessalonians, for they received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true.
Even Pauls words were to be examined by Scriptures to see if what Paul said was true. We cant find what the RCC says to be true from scripture.
