APOC'RYPHA, noun [Gr. from, to conceal.] Literally such things as are not published; but in an appropriate sense, books whose authors are not known; whose authenticity, as inspired writings, is not admitted, and which are therefore not considered a part of the sacred canon of the scripture. When the Jews published their sacred books, they called them canonical and divine; such as they did not publish, were called apocryphal. The apocryphal books are received by the Romish Church as canonical, but not by Protestants.
