The term apocrypha is used with various meanings, including "hidden", "esoteric", "spurious", "of questionable authenticity", and "Christian texts that are not canonical".
"The Apocrypha is included in Catholic Bibles. All are unauthentic, of unknown authorship, and without claim of inspiration or authority. Jews do not accept the Apocrypha as part of their Scriptures. The most influential benefactor of the Apocrypha was Augustine (354-420 AD), the "Father of corrupt theology." He influenced the Councils of Hippo (393 AD) and Carthage (397 AD) to declare the Apocrypha canonical. Augustine saw to it that any opposition to the Apocrypha was suppressed.
"Some of the unscriptural Roman Catholic doctrines supported by the Apocrypha are:
Purgatory (II Maccabees 12:39-45),
Salvation by Almsgiving (Ecclesiasticus 3:30),
Slavery and cruelty (Ecclesiasticus 33:24-28), and
Reincarnation (Wisdom of Solomon 8:19-20).
"Lying, assassination, and magical incantations are also approved of in the Apocrypha. Most Church Fathers rejected them; Josephus explicitly excluded them from his list; many of the Apocryphal books contain historical, geographical, and chronological errors; many of the Apocryphal books teach heresy, contrary to the Word of God; their literary style is legendary and fantasy, and some stories are grotesque and demonic; and they lack the power and distinctive elements of the Word of God."
