The Catholic approach to Scripture is quite different from that of most serious Protestants, especially Fundamentalists. To begin with, Protestants have neither Tradition nor Authority to enlighten their interpretations of Scripture. Since Scripture and Tradition are two forms of Revelation from the same God, and since the Petrine authority in the Church is established and protected by Christ, the Magisterium combines with Scripture and Tradition to give a complete and certain view of the truth. As the teachings of all three come from the same Holy Spirit, a right understanding of the Faith is possible only when all three are taken properly into account. (see The Catholic Approach to Scripture)
In the Second Vatican Council’s document on divine revelation, Dei Verbum (Latin: “The Word of God”), the relationship between Tradition and Scripture is explained: “Hence there exists a close connection and communication between sacred Tradition and sacred Scripture. For both of them, flowing from the same divine wellspring, in a certain way merge into a unity and tend toward the same end. For sacred Scripture is the word of God inasmuch as it is consigned to writing under the inspiration of the divine Spirit. To the successors of the apostles, sacred Tradition hands on in its full purity God’s word, which was entrusted to the apostles by Christ the Lord and the Holy Spirit. “Thus, by the light of the Spirit of truth, these successors can in their preaching preserve this word of God faithfully, explain it, and make it more widely known. Consequently it is not from sacred Scripture alone that the Church draws her certainty about everything which has been revealed. Therefore both sacred Tradition and sacred Scripture are to be accepted and venerated with the same devotion and reverence.” (see Scripture and Tradition)
The beliefs of Catholics are found in the Bible in two ways: explicit and implicit. Some teachings of the Catholic Church are easily found in the Bible. For example, that Jesus is the Son of God, that he called Twelve Apostles to follow him, that he healed, forgave sins, proclaimed the Kingdom of God present in his person, and that he suffered, died and rose again for our sins, are all very explicit in the Bible. The Holy Spirit makes known the full meaning of these events in and through the Church, and makes the power of these events effective throughout history and in our lives today.
