This means that Apelles accepted only one God, and made the creator but an angel who was completely under the power of the Supreme God. Marcion, on the contrary, held, as said below, two principles, teaching that the world-creator was himself a God, eternal, uncreated, and independent of the good God of the Christians. It is true that Marcion represented the world-creator as limited in power and knowledge, and taught that the Christian God would finally be supreme, and the world-creator become subject to him; but this, while it involves Marcion in self-contradiction as soon as the matter is looked at theoretically, yet does not relieve him from the charge of actual dualism. His followers were more consistent, and either accepted one principle, subordinating the world-creator completely to the good God, as did Apelles, or else carried out Marcion’s dualism to its logical result and asserted the continued independence of the Old Testament God and the world-creator, who was thus very early identified with Satan and made the enemy of the Christian God. (Marcion’s world-creator was not the bad God, but the righteous in distinction from the good God.) Still others held three principles: the good God of the Christians, the righteous God or world-creator, and the bad God, Satan. The varying doctrines of these schools explain the discrepant and often contradictory reports of the Fathers in regard to the doctrines of Marcion. Apelles’ doctrine was a decided advance upon that of Marcion, as he rejected the dualism of the latter, which was the destructive element in his system, and thus approached the Church, whose foundation must be one God who rules the world for good. His position is very significant, as remarked by Harnack, because it shows that one could hold Marcion’s fundamental principle without becoming a dualist.
