The Catechism on Sacred Scripture - Sections 107 & 108

107 The inspired books teach the truth. "Since therefore all that the inspired authors or sacred writers affirm should be regarded as affirmed by the Holy Spirit, we must acknowledge that the books of Scripture firmly, faithfully, and without error teach that truth which God, for the sake of our salvation, wished to see confided to the Sacred Scriptures."⁷²
 
108 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".⁷³ 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."⁷⁴
