The Catholic Bible is a collection of sacred texts used in the Catholic Church. It includes the Old Testament and the New Testament, with the Old Testament containing additional books known as the Deuterocanonical books, which are not found in the Protestant Bible. The Catholic Bible serves as a guide for faith and practice, providing teachings, history, and moral lessons. It is used in liturgy, personal study, and prayer, helping Catholics deepen their understanding of God and their relationship with Him.
