Catechism of the Catholic Church

Still, the Christian faith is not a "religion of the book." Christianity is the religion of the "Word" of God, a word which is "not a written and mute word, but the Word which is incarnate and living." If the Scriptures are not to remain a dead letter, Christ, the eternal Word of the living God, must, through the Holy Spirit, "open [our] minds to understand the Scriptures."
