I form the light, and create darkness: I make peace, and create calamity: I the LORD do all these things.
All Commentaries on Isaiah 45:7 Go To Isaiah 45
Tertullian of Carthage
AD 220
Now (like many other persons nowadays, especially those who have a heretical proclivity), while morbidly brooding over the question of the origin of evil, Marcion’s perception became blunted by the very irregularity of his researches. When he found the Creator declaring, “I am he that creates evil,” Marcion had already concluded from other arguments that satisfy only twisted minds that God is the author of evil. So Marcion now applied to the Creator the figure of the corrupt tree bringing forth evil fruit, that is, moral evil, and then presumed that there ought to be another god, after the analogy of the good tree producing its good fruit. Accordingly, finding in Christ a different disposition—one of a simple and pure benevolence, differing from the Creator—Marcion readily argued that in his Christ had been revealed a new and strange divinity; and then with a little leaven he leavened the whole lump of the faith, flavoring it with the acidity of his own heresy.
