GNOS'TIC, noun nostic. [Latin gnosticus; Gr. to know.]
The Gnostics were a sect of philosophers that arose in the first ages of christianity, who pretended they were the only men who had a true knowledge of the christian religion. They formed for themselves a system of theology, agreeable to the philosophy of Pythagoras and Plato, to which they accommodated their interpretations of scripture. They held that all natures, intelligible, intellectual and material, are derived by successive emanations from the infinite fountain of deity. These emanations they called oeons. These doctrines were derived from the oriental philosophy.
GNOS'TIC, adjective nostic. Pertaining to the Gnostics or their doctrines.
