If a Catholic truly does know Scripture, he also needs to demonstrate that in conversation: “Walk the walk,” don’t just “talk the talk.” The more we show that Bible and Catholicism are not contradictory terms, the more we appeal to Protestants with the truth of our overall message. 

We can show how it is possible to break out of the stereotype by example, and by demonstrating in argument that the Catholic Church is far more the truly “biblical” Church than any form of Protestantism. We take all of Scripture into account, not just our favorite verses and proof texts. We laboriously preserved Scripture all those hundreds of years before Protestantism ever saw the light of day; we canonized it; we developed all the major branches of theology based upon it before Luther and Calvin even existed.

It’s good to reject sola scriptura (Bible alone) and submit to the mind of the Church, but it is also good to show forth a positive love for Scripture. That comes only by reading it and becoming better acquainted with its contents. If the Mass alone were sufficient for that end, then Catholics would already know their Bibles better than Protestants. But they obviously don’t. So I regard it as a self-evident truth that Catholics need to do more study apart from the liturgy, prayer books, and rosaries. We need to read the Bible itself, frequently and often. Merely reading a Bible doesn’t prove love of God, but a person who truly loves God will long to read the words of his beloved.

Thus faith comes from what is heard, and what is heard comes through the word of Christ. (Romans. 10:17)

Indeed, the word of God is living and effective, sharper than any two-edged sword, penetrating even between soul and spirit, joints and marrow, and able to discern reflections and thoughts of the heart. (Hebrews. 4:12)

All scripture is inspired by God and is useful for teaching, for refutation, for correction, and for training in righteousness, so that one who belongs to God may be competent, equipped for every good work. (2 Timothy. 3:16-17)

Your word is a lamp for my feet, a light for my path. (Psalm. 119:105)

Let no one have contempt for your youth, but set an example for those who believe, in speech, conduct, love, faith, and purity. Until I arrive, attend to the reading, exhortation, and teaching. (1 Timothy. 4:12-13)
