Apocrypha are biblical or related writings not forming part of the accepted canon of scripture, some of which might be of doubtful authorship or authenticity. In Christianity, the word apocryphal (ἀπόκρυφος) was first applied to writings that were to be read privately rather than in the public context of church services. Apocrypha were edifying Christian works that were not always initially included as canonical scripture. The adjective "apocryphal", meaning of doubtful authenticity, mythical, fictional, is recorded from the late 16th century, then taking on the popular meaning of "false," "spurious," "bad," or "heretical." It may be used for any book which might have scriptural claims but which does not appear in the canon accepted by the author. A related term for non-canonical apocryphal texts whose authorship seems incorrect is pseudepigrapha, a term that means "false attribution". In Christianity, the name "the Apocrypha" is applied to a particular set of books which, when they appear in a Bible, are sometimes placed between the Old and New Testaments in a section called "Apocrypha." The canonicity of such books took longer to determine. Various of these books are accepted by the Catholic Church, Orthodox Churches and the Church of the East, as deuterocanonical. Some Protestant traditions reject them outright; others regard the Apocrypha as non-canonical books that are useful for instruction. Source: Wikipedia (en)
