Who authorized you to interpret Scripture? Seriously — who? Where does your authority come from, that anyone should listen to you?
I simply re-quoted a passage of Scripture that one of your Roman Catholic friends had quoted.
Is it impermissible to quote Scripture? If so, rebuke your Roman Catholic friends before you start laying into me.
To respond to your question: Jesus authorizes me to relish His Word, and to share its truths with others. Do you not ponder the Scriptures? If not, I welcome you to do so.
