Apocrypha

(from Greek apokryptein, "to hide away"), in biblical literature, works outside an accepted canon of scripture. The history of the term's usage indicates that it referred to a body of esoteric writings that were at first prized, later tolerated, and finally excluded. In its broadest sense apocrypha has come to mean any writings of dubious authority.

There are several levels of dubiety within the general concept of apocryphal works in Judeo-Christian biblical writings. Apocrypha per se are outside the canon, not considered divinely inspired but regarded as worthy of study by the faithful. Pseudepigrapha are spurious works ostensibly written by a biblical figure. Deuterocanonical works are those that are accepted in one canon but not in all.

At the time when Greek was the common spoken language in the Mediterranean region, the Old Testament--the Hebrew Bible--was incomprehensible to most of the population. For this reason, Jewish scholars produced the Septuagint, a translation of the Old Testament books from various Hebrew texts, along with fragments in Aramaic, into Greek. That version incorporated a number of works that later, non-Hellenistic Jewish scholarship at the Council of Jamnia (ad 90) identified as being outside the authentic Hebrew canon. The Talmud separates these works as Sefarim Hizonim (Extraneous Books).

The Septuagint was an important basis for St. Jerome's translation of the Old Testament into Latin for the Vulgate Bible; and, although he had doubts about the authenticity of some of the apocryphal works that it contained (he was the first to employ the word apocrypha in the sense of "noncanonical"), he was overruled, and most of them were included in the Vulgate. On April 8, 1546, the Council of Trent declared the canonicity of nearly the entire Vulgate, excluding only the Third and Fourth Books of Maccabees, the Prayer of Manasseh, Psalm 151, and the First and Second Books of Esdras. Eastern Christendom, meanwhile, had accepted some of the Old Testament apocrypha--Tobit, Judith, the Wisdom of Solomon, and Ecclesiasticus (Wisdom of Jesus the Son of Sirach)--but rejected the rest.

The other apocryphal writings, canonical only to Roman Catholicism, with an exception or two, include the Book of Baruch (a prophet) and the Letter of Jeremiah (often the sixth chapter of Baruch); the First and Second Books of Maccabees; several stories from Daniel, namely, the Song of the Three, Susanna, and Bel and the Dragon; and extensive portions of the Book of Esther.

Old Testament pseudepigrapha are extremely numerous and offer accounts of patriarchs and events, attributed to various biblical personages from Adam to Zechariah. Some of the most significant of these works are the Ascension of Isaiah, the Assumption of Moses, the Life of Adam and Eve, the First and Second Books of Enoch, the Book of Jubilees, the Letter of Aristeas, and the Testaments of the Twelve Patriarchs.

All the New Testament apocrypha are pseudepigraphal, and most of them fall into the categories of acts, gospels, and epistles, though there are a number of apocalypses and some can be characterized as wisdom books. The apocryphal acts purport to relate the lives or careers of various biblical figures, including most of the apostles; the epistles, gospels, and others are ascribed to such figures. Some relate encounters and events in mystical language and describe arcane rituals. Most of these works arose from sects that had been or would be declared heretical, such as, importantly, the Gnostics. Some of them argued against various heresies, and a few appear to have been neutral efforts to popularize the life of some saint or other early leader of the church, including a number of women. In the early decades of Christianity no orthodoxy had been established, and various parties or factions were vying for ascendancy and regularity in the young church. All sought through their writings, as through their preaching and missions, to win believers. In this setting virtually all works advocating beliefs that later became heretical were destined to denunciation and destruction.

In addition to apocryphal works per se, the New Testament includes a number of works and fragments that are described by a second meaning of the term deuterocanonical: "added later." The Letter to the Hebrews attributed to Paul, who died before it was written, is one of these; others are the letters of James, Peter (II), John (II and III), and Jude, and the Revelation to John. Fragments include Mark 16:9-20, Luke 22:43-44, and John 7:53 and 8:1-11. All are included in the Roman canon and are accepted by the Eastern Church and most Protestant churches.

Heretical movements such as Gnosticism and Montanism spawned a great body of New Testament pseudepigrapha. The existence of such purported scriptures lent great impetus to the process of canonization in the young and orthodox Christian Church. See also various apocryphal works cited above.
