Some people read special books in the Old Testament. These are called deuterocanonical books. This is a long word. It means they belong to a second list of holy books. 
Different groups of people have different ideas about them. The Catholic and Eastern Orthodox churches use these books. They see them as part of their holy scripture. But, Protestant groups and modern Judaism do not. They call these books Apocrypha instead.
These books are very old. Most were written between 300 BC and 100 AD. They are found in the Septuagint. This was an early Greek translation of the Hebrew Bible. We even find parts of them in very old scrolls found in caves. One book is called Tobit. Another is called Judith. There is also a book called Wisdom.
Many early church leaders used these books in their writing. Some councils held long meetings to decide which books to include. These meetings helped set the lists used by churches today. It is a big part of how people study faith. Do you like learning about old books?
The term deuterocanonical refers to a specific group of books. These books belong to a "second canon," which means a second list. 
How these books are used depends on the faith tradition. Many ancient churches accept seven books as deuterocanonical. These include Tobit, Judith, and Baruch with the Letter of Jeremiah. Other books include Sirach, Wisdom, and First and Second Maccabees. Some also include Greek additions to the books of Esther and Daniel. 
These books have a very long history. Most were written between 300 BC and 100 AD. This was before the Christian church and Judaism fully separated. They were part of the Septuagint, an early Greek translation of the Hebrew Bible. 
We know these books are very old because of physical evidence. Archaeologists found fragments of these books in the Dead Sea Scrolls. For example, pieces of Tobit were found in Qumran written in Aramaic and Hebrew. 
These books connect to many things people study today. For instance, some believe the New Testament refers to events in 2 Maccabees. The book of Hebrews mentions an Old Testament prophet in a way that some link to this book. 
The term deuterocanonical refers to a specific collection of books and passages. The name comes from the Greek words meaning "of, pertaining to, or constituting a second canon." In religious studies, a canon is an official list of books considered sacred. The deuterocanonical books are viewed as part of the Old Testament by several major traditions. These include the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox Church, and the Church of the East. However, modern Protestantism and Rabbinic Judaism do not include them in their official lists. Instead, they often refer to these texts as the Apocrypha. 
Different religious groups hold different views on which books belong in this category. All ancient churches generally accept seven specific books as deuterocanonical. These are Tobit, Judith, Baruch with the Letter of Jeremiah, Sirach, Wisdom, First and Second Maccabees, and Greek additions to Esther and Daniel. The Eastern Orthodox and Oriental Orthodox Churches include additional texts. Their lists might include the Prayer of Manasseh, 1 Esdras, 2 Esdras, 3 Maccabees, 4 Maccabees, or Psalm 151. These variations exist because different traditions recognize different sets of ancient writings. This demonstrates how religious libraries can vary across different branches of faith.
These books are deeply connected to the Septuagint. The Septuagint is the earliest known Greek translation of the Hebrew Bible. Most of the deuterocanonical books were written between 300 BC and 100 AD. This period occurred before the Christian church and Judaism became fully separated. Because they were part of the Septuagint, they were used widely by early Christians. Many Old Testament references found in the New Testament are actually taken from the Koine Greek Septuagint. This includes both deuterocanonical books and other apocryphal works. 
History shows that the term "deuterocanonical" is not as old as the books themselves. The term was coined in 1566 by a theologian named Sixtus of Siena. Sixtus had converted to Catholicism from Judaism. He used the term to describe scriptures that the Catholic Church considered canonical but "secondary." Originally, he applied the term to portions of both the Old and New Testaments. Later writers narrowed the definition. They used it specifically for Old Testament books recognized by various Church Councils. These councils included Rome in 382 AD, Hippo in 393 AD, and Carthage in 397 AD and 419 AD. 
Archaeological discoveries provide physical evidence of these ancient texts. The Dead Sea Scrolls contain fragments of several deuterocanonical books. For instance, researchers found five fragments of the Book of Tobit in Qumran. These were written in Aramaic and Hebrew. The Hebrew text of Sirach has also been found in the Dead Sea Scrolls and at Masada. Even the Letter of Jeremiah was discovered as a Greek papyrus in cave 7. These finds help scholars understand how these books were preserved. Some suggest the Qumran library might have included parts of the Jerusalem Temple library. 
Early religious leaders often discussed these books in their writings. The Jewish historian Josephus wrote that the Hebrew Bible contained 22 canonical books. The Christian bishop Athanasius also reported a count of 22 books in 367 AD. However, the specific contents of those lists often differed. Athanasius included Baruch and the Letter of Jeremiah, but he omitted Esther. He also mentioned that books like Wisdom of Solomon and Judith were "appointed by the Fathers to be read," even if they were not part of the formal canon. Other figures, such as Cyril of Jerusalem and Augustine of Hippo, also provided different lists of scripture. 
These books continue to influence how scholars study the connections between different religious texts. For example, some researchers believe the New Testament book of Hebrews refers to events in 2 Maccabees. Hebrews 11:35-37 mentions an Old Testament prophet who was sawn in half. Some scholars link this specific detail to the stories found in 2 Maccabees. Additionally, other New Testament authors are believed to have referenced or quoted period literature. By studying these books, we see the complex ways that ancient ideas and traditions were shared and recorded throughout history.
