Apocrypha

n. Old Testament books not included in the Bible

Apocrypha (from the Greek word , meaning "those having been hidden away") are texts of uncertain authenticity or writings where the authorship is questioned. In Judeo-Christian theology, the term apocrypha refers to any collection of scriptural texts that falls outside the canon. Given that different denominations have different ideas about what constitutes canonical scripture, there are several different versions of the apocrypha. During sixteenth-century controversies over the biblical canon the word "apocrypha" acquired a negative connotation, and it has become a synonym for "spurious" or "false". This usage usually involves fictitious or legendary accounts that are plausible enough to commonly be considered as truth. For example, the Parson Weems account of George Washington and the cherry tree is considered apocryphal.

Apocrypha [from Greek apokryphos secret] Esoteric, hid, secret; later spurious. First applied to writings regarded as esoteric, for private instruction, and of profounder import than the exoteric writings; but the rise of bogus esoteric schools gradually brought the word into contempt and clothed it with its later meaning of spurious or doubtful.
