Can you imagine life without your past? While there are probably some memories that bother you, all of your memories have contributed to who you are today. So it is with the Bible. The Old and New Testaments go hand in hand, revealing the truths for salvation.
We can no more negate the history of creation and lessons of the prophets, than you can erase your birth and childhood. The Canon of Scripture decidedly includes and attests to the validity of all of the books in the Bible. Carried on through the apostolic Tradition, Church Canon affirms the unity of the Old Testament with the New Testament, placing special emphasis on the lessons in the Gospels.
The Gospels are important because they reveal the life, ministry and teachings of Christ when He walked among us. They refer to the oral tradition of faith, passed on verbally throughout the ages, and support the written tradition of faith, emphasizing the Revelation of the Word.
All of the faithful are highly encouraged to read and study Sacred Scripture, and are informed of its lessons in every Mass offered for the sake of salvation. The Catholic Church has always recognized the importance of the Bible, as proven by the detailed emphasis in its Catechism, throughout chapter two.
