I'll save you time. You can't. The visible Body of Christ, the Church (That's we Catholics, son) is cited 110 times in the New Testament while "Scripture" is cited 54 times.
Add that to the fact it is we Catholics who wrote the Scripture you use to try and oppose the Catholic Church and you have yourself one knotty problem which you can try to solve during Lent.
P.S. It is said fasting tends to produce clarity of thought.
Have a nice day.
You really don't want to go there, do you? The Gospels were written by some guys named Matthew, Mark, Luke, and John. Many of the epistles were writtne by the Apostle Paul, others by James, Peter, and Jude. Where are the Roman Catholic authors in that group (Peter doesn't count - he never went to Rome)
And the Old Testament: Moses, Daniel, many prophets, Solomon, etc...again, no Roman Catholics in that group either.
