The Catholic Bible includes 73 books, 46 in the Old Testament and 27 in the New Testament.
The Christian Bible, on the other hand, has 66 books, with 39 in the Old Testament and 27 in the New Testament.
The main difference between the two is that the Catholic Bible includes several books (known as the Deuterocanonical books) that are considered as canonical by the Catholic Church but are considered as non-canonical by Protestant denominations.
In general, the Protestant denominations use the Christian Bible, while the Catholic Church uses the Catholic Bible. Both versions contain the same 27 books in the New Testament, which include the four Gospels (Matthew, Mark, Luke, and John), the Acts of the Apostles, letters from various apostles to early Christian communities, and the book of Revelation.
The primary difference between the two Bibles is the number and content of the books in the Old Testament. The Deuterocanonical books included in the Catholic Bible are Tobit, Judith, Wisdom, Sirach (also called Ecclesiasticus), Baruch, and First and Second Maccabees. These books are accepted by the Catholic Church as part of the inspired scriptures but are not accepted by most Protestant denominations.
