There’s only one author for Sacred Scripture, God Himself. While individual books are attributed to several different people, the Catholic Church recognizes that all of Scripture has been inspired by the Spirit of the Living Word. The Holy Spirit affirmed the writings of men especially chosen by God to reveal His truth, necessary for our salvation.
“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.” CCC
Again we are directed to Christ as our leader. It is only through God’s Son that we will receive mercy and forgiveness for our sins. This is a free gift, one that we could never earn or purchase. When we read the dynamic passages in the Bible, we are taught lessons that will guide us truthfully in our lives. It is up to us to respond to the inspirations of the Spirit in faith, and when we do, we will stand firm in the path that leads to God.
