Of the Vanity and Crimes, Impious Superstitions, and of the Tortures of the Christians
were instituted by crafty men, that the people may not know what they worship. But since we are acquainted with their systems, why do they either not believe us who are acquainted with both, or envy us because we have preferred truth to falsehood? But, they say, the public rites of religion must be defended. Oh with what an honourable inclination the wretched men go astray! For they are aware that there is nothing among men more excellent than religion, and that this ought to be defended with the whole of our power; but as they are deceived in the matter of religion itself, so also are they in the manner of its defence.
For religion is to be defended, not by putting to death, but by dying; not by cruelty, but by patient endurance; not by guilt, but by good faith: for the former belong to evils, but the latter to goods; and it is necessary for that which is good to have place in religion, and not that which is evil. For if you wish to defend religion by bloodshed, and by tortures, and by guilt, it will no longer be defended, but will be polluted and profaned. For nothing is so much a matter of free-will as religion; in which, if the mind of the worshipper is disinclined to it, religion is at once taken away, and ceases to exist.
The right method therefore is, that you defend religion by patient endurance or by death; in which the preservation of the faith is both pleasing to God Himself, and adds authority to religion. For if he who in this earthly warfare preserves his faith to his king in some illustrious action, if he shall continue to live, because more beloved and acceptable, and if he shall fall, obtains the highest glory, because he has undergone death for his leader; how much more is faith to be kept towards God, the Ruler of all, who is able to pay the reward of virtue, not only to the living, but also to the dead!
Therefore the worship of God, since it belongs to heavenly warfare, requires the greatest devotedness and fidelity. For how will God either love the worshipper, if He Himself is not loved by him, or grant to the petitioner whatever he shall ask, when he draws near to offer his prayer without sincerity or reverence? But these men, when they come to offer sacrifice, present to their gods nothing from within, nothing of their own— no uprightness of mind, no reverence or fear. Therefore, when the worthless sacrifices are completed, they leave their religion altogether in the temple, and with the temple, as they had found it; and neither bring with them anything of it, nor take anything back.
Hence it is that religious observances of this kind are neither able to make men good, nor to be firm and unchangeable. And thus men are easily led away from them, because nothing is learned in them relating to the life, nothing relating to wisdom, nothing to faith. For what is the religion of those gods? What is its power? What its discipline? What its origin? What its principle? What its foundation? What its substance? What is its tendency? Or what does it promise, so that it may be faithfully preserved and boldly defended by man?
I see nothing else in it than a rite pertaining to the fingers only. But our religion is on this account firm, and solid, and unchangeable, because it teaches justice, because it is always with us, because it has its existence altogether in the soul of the worshipper, because it has the mind itself for a sacrifice. In that religion nothing else is required but the blood of animals, and the smoke of incense, and the senseless pouring out of libations; but in this of ours, a good mind, a pure breast, an innocent life: those rites are frequented by unchaste adulteresses without any discrimination, by impudent procuresses, by filthy harlots; they are frequented by gladiators, robbers, thieves, and sorcerers, who pray for nothing else but that they may commit crimes with impunity.
For what can the robber ask when he sacrifices, or the gladiator, but that they may slay? What the poisoner, but that he may escape notice? What the harlot, but that she may sin to the uttermost? What the adulteress, but either the death of her husband, or that her unchastity may be concealed? What the procuress, but that she may deprive many of their property? What the thief, but that he may commit more peculations? But in our religion there is no place even for a slight and ordinary offense; and if any one shall come to a sacrifice without a sound conscience, he hears what threats God denounces against him: that God, I say, who sees the secret places of the heart, who is always hostile to sins, who requires justice, who demands fidelity.
What place is there here for an evil mind or for an evil prayer? But those unhappy men neither understand from their own crimes how evil it is to worship, since, defiled by all crimes, they come to offer prayer; and they imagine that they offer a pious sacrifice if they wash their skin; as though any streams could wash away, or any seas purify, the lusts which are shut up within their breast. How much better it is rather to cleanse the mind, which is defiled by evil desires, and to drive away all vices by the one laver of virtue and faith! For he who shall do this, although he bears a body which is defiled and sordid, is pure enough.
