Aprocrypha/Deuterocanonical
What it is
The Apocrypha is a collection of texts regarded as part of the OT by Roman Catholic and Orthodox Christians but not regarded as part of the OT by Protestant Christians.
The term “Apocrypha” itself comes from a Greek word meaning “hidden things”—in this case, hidden books—and that term reflects the Protestant position on the place of these books in the canon of Scripture. These same books will be called deuterocanonical in the Catholic and Orthodox church or simply known as part of the OT.
These books were all written between about 200 BC and AD 100.
Now, the books of the Apocrypha are not the only Jewish literature that comes from this period. Dozens upon dozens of other books were written by Jews in all of these centers in multiple languages, but the Apocrypha comes as a collection specifically because of the reading practices of different Christian communities. One thing is certain: We would not speak today of the Apocrypha as a collection of Jewish texts had the church in every age not revered these particular books and drawn constant inspiration from them alongside those Jewish texts that are collected in the Hebrew Bible and, above all, other Jewish literature beyond the Hebrew Bible and the NT.
