The three major Christian Confessions today accept a different number of books from the Old Testament, but they have in common the system of classifying books according to the character of the biblical works. Thus, the books are classified according to their character into three groups: "Historical", "Poetic-Didactic", and "Prophetic". The tradition of the Orthodox Church accepts as "canonical" (books that belong to the canon), apart from the 39 books of the Jewish Bible (which, however, are titled according to the Septuagint), an additional 10 books (1 Esdras, Tobit, Judith, 1-2-3 Maccabees, Wisdom of Solomon, Sirach, Baruch, and the Letter of Jeremiah). The Roman Catholic Church followed a similar practice, eventually accepting 46 books, which it distinguishes as "proto-canonical" and "deuterocanonical". Finally, the Churches that emerged from the Reformation accepted the canon of the Jewish Bible with the 39 books.
