The term 'Scripture' refers to the sacred writing of the Old and New Testaments. The Holy Scriptures are the books that "contain the truth of God's revelation and were composed by human authors inspired by the Holy Spirit" (CCC 105). Sacred Scripture is one of the many names that designate the inspired writings that make up the Old and New Testaments. The words of the Holy Scriptures, "for their part, announce the works and illuminate the mystery they contain". The term Tradition refers to the living transmission of the Gospel in the Church. ?The oral preaching of the Apostles and the written message of salvation under the inspiration of the Holy Spirit are preserved and transmitted as a deposit of faith through the apostolic succession in the Church? (CCC 77-78). The sacred or apostolic tradition consists of the teachings that the apostles transmitted orally through their preaching. These teachings overlap with those contained in Scripture, but the method of their transmission is different. However, Tradition generally refers to Christian teachings and practices outside the Bible that are passed down from generation to generation. Sacred Scripture and Tradition consist of similar teachings, but these teachings are transmitted in different ways, ??Sacred Scripture is the speech of God as it is written down under the breath of the Holy Spirit?? (CCC 81) while, ?? Does Tradition transmit in its entirety the Word of God which was entrusted to the apostles by Christ the Lord and the Holy Spirit?? (CCC 81) Scripture and Tradition are linked in Catholic theology. Connected to each other, ?Sacred Tradition and Sacred Scripture constitute a single deposit of the Word of God? (CCC 97). ?Both living Tradition and written Scripture have their common source in the revelation of God in Jesus Christ? (CCC 75-82). Catholics see Scripture and Tradition as two sources of revelation. Revelation is the way in which God reveals his divine plan to all humanity, it is God's communication of himself, through which he makes known the mystery of his divine plan. (CCC 50). God reveals himself through Sacred Scripture and Catholic Tradition. God revealed Himself most completely through the Son (The Word), Jesus Christ, and there will be no further Revelation after Him. However, through Scripture and Tradition, the mystery of God has been passed down through the centuries.
