Epiph. Hær. 41, sec. 1. “Cerdon [circ. A.D. 150] with others preached two first principles, and so in fact two Gods: the one good, and unknown to all: whom he also called the Father of Jesus: the other, the Demiurgus, or artificer, evil, and open to knowledge, who spake in the law, and appeared in the prophets, and hath often become visible.” In this he agreed with the Oriental heretics generally. Marcion, his disciple, within a few years improved on him (Hær. 42, sec. 3), “saying, that there are three principles: one, that on high, unnamed, and unseen, which it pleases him to call the good God (this however, was not the Creator of any of the things that are in the world): another, a visible God, Creator and Artificer: and, in the third place, the devil.…Now the Creator, and Artificer, and visible One, they say, is the God of the Jews, and is also the Judge.” Cf. ibid. sec. 6; St. Aug. de Hæres. 22; Tertull. contr. Marc. i. 10 [Ante-Nicene Fathers, vol. III. p. 278]; St. Iren. i. 28, 29 [Ante-Nicene Fathers, vol. I. pp. 352, 353].
