 The term is derived from the Second Epistle to the Thessalonians, in which the Apostle Paul informs the Christians of Thessalonica that a great apostasy must occur before the return of Christ, when "the man of sin is revealed, the son of destruction" (chapter ).The Catholic Church, Anglican Church, Eastern and Oriental Orthodox Churches have interpreted this chapter as referring to a future falling-away, during the reign of the Antichrist at the end of times.Some modern scholars believe that the Church in the early stages picked up pagan oral teachings from Palestinian and Hellenistic sources, which formed the basis of a secret oral tradition, which in the 4th century came to be called the "disciplina arcani".
