We have discovered the primary problem with the roman catholic understanding of the Word.
They don't study the GREEK!!!!
Here's some advice....ditch the latin and study the Greek and Hebrew.
Rather, study all the above, Latin, Greek, and Hebrew, the languages of the world of the Bible.
You are quite correct in this. It was Luther's contemporary Catholic friend Desiderius Erasmus, who compiled what is now known as the Received Text, a Byzantine/Majority textform, that Luther read the Koine and through its lucid opening chapter of Paul's epistle to the Romans came to discover the Heavenly brilliance of salvation on the basis of faith alone in the Biblical Jesus alone, interpreting Habakkuk 2, and thereby led Spirit-filled humans out of the error-filled religious denomination, forever.
