Yes, Roman Catholics do believe in the Bible. The Bible is considered sacred and authoritative in the Catholic faith, and it is one of the key sources of religious doctrine and guidance. The Catholic Church recognizes the Bible as the inspired Word of God and considers it a fundamental part of its tradition.
The Catholic Bible includes both the Old Testament and the New Testament. The Old Testament contains books that are also present in the Hebrew Bible, while the New Testament contains the Gospels, Acts of the Apostles, letters (epistles), and the Book of Revelation.
Catholics follow a liturgical calendar, and readings from the Bible are an integral part of their worship services, especially during the Mass. Different passages from the Old and New Testaments are read and reflected upon throughout the liturgical year.
It’s important to note that the Catholic Church has an interpretative tradition that includes the teachings of the Magisterium (the teaching authority of the Church), which helps guide the understanding and application of biblical texts. The Magisterium, consisting of the pope and the bishops in communion with him, plays a role in interpreting the Bible and applying its teachings to contemporary issues within the framework of Catholic theology.
While the Bible is highly revered and central to Catholic faith and practice, the Catholic Church also draws on other sources of authority, such as sacred tradition and the teachings of the Magisterium, to guide its beliefs and practices.
