Answer to the Objection of the Heathen, that It Was Not Right to Abandon the Customs of Their Fathers
But you say it is not creditable to subvert the customs handed down to us from our fathers. And why, then, do we not still use our first nourishment, milk, to which our nurses accustomed us from the time of our birth? Why do we increase or diminish our patrimony, and not keep it exactly the same as we got it? Why do we not still vomit on our parents' breasts, or still do the things for which, when infants, and nursed by our mothers, we were laughed at, but have corrected ourselves, even if we did not fall in with good instructors? Then, if excesses in the indulgence of the passions, though pernicious and dangerous, yet are accompanied with pleasure, why do we not in the conduct of life abandon that usage which is evil, and provocative of passion, and godless, even should our fathers feel hurt, and betake ourselves to the truth, and seek Him who is truly our Father, rejecting custom as a deleterious drug? For of all that I have undertaken to do, the task I now attempt is the noblest, viz., to demonstrate to you how inimical this insane and most wretched custom is to godliness. For a boon so great, the greatest ever given by God to the human race, would never have been hated and rejected, had not you been carried away by custom, and then shut your ears against us; and just as unmanageable horses throw off the reins, and take the bit between their teeth, you rush away from the arguments addressed to you, in your eager desire to shake yourselves clear of us, who seek to guide the chariot of your life, and, impelled by your folly, dash towards the precipices of destruction, and regard the holy word of God as an accursed thing. The reward of your choice, therefore, as described by Sophocles, follows:—
“The mind a blank, useless ears, vain thoughts.”
And you know not that, of all truths, this is the truest, that the good and godly shall obtain the good reward, inasmuch as they held goodness in high esteem; while, on the other hand, the wicked shall receive meet punishment. For the author of evil, torment has been prepared; and so the prophet Zecharias threatens him: “He that has chosen Jerusalem rebuke you; lo, is not this a brand plucked from the fire?” What an infatuated desire, then, for voluntary death is this, rooted in men's minds! Why do they flee to this fatal brand, with which they shall be burned, when it is within their power to live nobly according to God, and not according to custom? For God bestows life freely; but evil custom, after our departure from this world, brings on the sinner unavailing remorse with punishment. By sad experience, even a child knows how superstition destroys and piety saves. Let any of you look at those who minister before the idols, their hair matted, their persons disgraced with filthy and tattered clothes; who never come near a bath, and let their nails grow to an extraordinary length, like wild beasts; many of them castrated, who show the idol's temples to be in reality graves or prisons. These appear to me to bewail the gods, not to worship them, and their sufferings to be worthy of pity rather than piety. And seeing these things, do you still continue blind, and will you not look up to the Ruler of all, the Lord of the universe? And will you not escape from those dungeons, and flee to the mercy that comes down from heaven? For God, of His great love to man, comes to the help of man, as the mother-bird flies to one of her young that has fallen out of the nest; and if a serpent open its mouth to swallow the little bird, “the mother flutters round, uttering cries of grief over her dear progeny;” and God the Father seeks His creature, and heals his transgression, and pursues the serpent, and recovers the young one, and incites it to fly up to the nest.
Thus dogs that have strayed, track out their master by the scent; and horses that have thrown their riders, come to their master's call if he but whistle. “The ox,” it is said, “knows his owner, and the ass his master's crib; but Israel has not known Me.” What, then, of the Lord? He remembers not our ill desert; He still pities, He still urges us to repentance.
And I would ask you, if it does not appear to you monstrous, that you men who are God's handiwork, who have received your souls from Him, and belong wholly to God, should be subject to another master, and, what is more, serve the tyrant instead of the rightful King— the evil one instead of the good? For, in the name of truth, what man in his senses turns his back on good, and attaches himself to evil? What, then, is he who flees from God to consort with demons? Who, that may become a son of God, prefers to be in bondage? Or who is he that pursues his way to Erebus, when it is in his power to be a citizen of heaven, and to cultivate Paradise, and walk about in heaven and partake of the tree of life and immortality, and, cleaving his way through the sky in the track of the luminous cloud, behold, like Elias, the rain of salvation? Some there are, who, like worms wallowing in marshes and mud in the streams of pleasure, feed on foolish and useless delights— swinish men. For swine, it is said, like mud better than pure water; and, according to Democritus, “doat upon dirt.”
