Still, the Christian faith is not a "religion of the book". Christianity is the religion of the "Word" of God, "not a written and mute word, but 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."
