Then because the term “philosophy” has an appearance of dignity, he added, “and vain deceit.” For there is also a good deceit; such as many have been deceived by, which one ought not even to call a deceit at all. Whereof Jeremiah speaks; “O Lord, Thou hast deceived me, and I was deceived” (Jer. xx. 7.); for such as this one ought not to call a deceit at all; for Jacob also deceived his father, but that was not a deceit, but an economy. “Through his philosophy,” he saith, “and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ.” Now he sets about to reprove their observance of particular days, meaning by elements of the world the sun and moon; as he also said in the Epistle to the Galatians, “How turn ye back again to the weak and beggarly elements?” (Gal. iv. 9.) And he said not observances of days, but in general of the present world, to show its worthlessness: for if the present world be nothing, much more then its elements. Having first shown how great benefits and kindnesses they had received, he afterwards brings on his accusation, thereby to show its greater seriousness, and to convict his hearers. Thus too the Prophets do. They always first point out the benefits, and then they magnify their accusation; as Esaias saith, “I have begotten children, and exalted them, but they have rejected me” (Isa. i. 2, Sept.); and again, “O my people, what have I done unto thee, or wherein have I grieved thee, or wherein have I wearied thee”? (Mic. vi. 3.) and David; as when he says, “I heard thee in the secret place of the tempest” (Ps. lxxxi. 7, Sept.); and again, “Open thy mouth, and I will fill it.” (Ps. lxxxi. 10.) And everywhere you will find it the same.
