Antitactae: (Antitactes) May refer to a sect, or independent or ascetic (licentious, antinomian) Gnostics, rather than the followers of any single master, to whom they can be traced.
Apelles: A Gnostic follower of Marcion who later disagreed with Marcionite philosophies, especially concerning docetics and dualism. His work “Hexaëmeron” was an attempt to refute Moses.
Apocalypse: A writing which relates a revelation, usually associated with doom.
(See; ”The Apocalypse of Paul,” NHL.) Apocalypse (Greek: Ἀποκάλυψις –translit. APOKALYPSIS, literally: the lifting of the veil), is a term applied to the disclosure to certain privileged persons of something hidden from the mass of humankind. Today the term is often used to mean “end of the world”, which may be a shorterning of the phrase apokalupsis eschaton which literally means “revelation at the end of the world”.
An Apocalypse in the terminology of early Jewish and Christian literature, is a revelation of hidden things given by God to a chosen prophet; the term is often used to describe the written account of such a revelation. Apocalyptic literature is of considerable importance in the history of the Judeo–Christian–Islamic tradition, because it makes specific reference to beliefs such as the resurrection of the dead, judgment day, eternal life and perdition. Apocalyptic beliefs predate Christianity, appear in other religions, and have merged into contemporary secular society, especially through popular culture (see Apocalypticism). Apocalypse-like beliefs also occur in other religious systems; an example is the Hindu concept of pralay.
From the second century, the term “Apocalypse” was applied to a number of books, both Jewish and Christian, which show the same characteristic features. Besides the Apocalypse of John (now generally called the Book of Revelation) included in the New Testament, the Muratorian fragment, Clement of Alexandria, and others mention an Apocalypse of Peter. Apocalypses of Adam and Abraham (Epiphanius) and of Elias (Jerome) are also mentioned; see, for example, the six titles of this kind in the “List of the 60 Canonical Books”. The use of the Greek noun to designate writings belonging to a certain literary genre is of Christian origin, the original norm of the class being the New Testament Book of Revelation. In 1832 Gottfried Christian Friedrich Lücke explored the word “Apocalypse” as a description of the book of Revelation, a usage obtained from the opening words of the book which refer to an apocalypse (prophecy) of Jesus Christ given to John, who wrote the text. In Greek the opening words are ‘Aπōκάλυψις ‘Iησōῦ Χριστōῦ.
