Reply to Faustus the Manichaean

⁷⁰ It might be shown that, though Moses slew the Egyptian, without being commanded by God, the action was divinely permitted, as, from the prophetic character of Moses, it prefigured something in the future. Now however, I do not use this argument, but view the action as having no symbolic meaning. In the light, then, of the eternal law, it was wrong for one who had no legal authority to kill the man, even though he was a bad character, besides being the aggressor. But in minds where great virtue is to come, there is often an early crop of vices, in which we may still discern a disposition for some particular virtue, which will come when the mind is duly cultivated.

For as farmers, when they see land bringing forth huge crops, though of weeds, pronounce it good for grain; or when they see wild creepers, which have to be rooted out, still consider the land good for useful vines; and when they see a hill covered with wild olives, conclude that with culture it will produce good fruit: so the disposition of mind which led Moses to take the law into his own hands, to prevent the wrong done to his brother, living among strangers, by a wicked citizen of the country from being unrequited, was not unfit for the production of virtue, but from want of culture gave signs of its productiveness in an unjustifiable manner.

He who afterwards, by His angel, called Moses on Mount Sinai, with the divine commission to liberate the people of Israel from Egypt, and who trained him to obedience by the miraculous appearance in the bush burning but not consumed, and by instructing him in his ministry, was the same who, by the call addressed from heaven to Saul when persecuting the Church, humbled him, raised him up, and animated him; or in figurative words, by this stroke He cut off the branch, grafted it, and made it fruitful.

For the fierce energy of Paul, when in his zeal for hereditary traditions he persecuted the Church, thinking that he was doing God service, was like a crop of weeds showing great signs of productiveness. It was the same in Peter, when he took his sword out of its sheath to defend the Lord, and cut off the right ear of an assailant, when the Lord rebuked him with something like a threat, saying, "Put up your sword into its sheath; for he that takes the sword shall perish by the sword." To take the sword is to use weapons against a man's life, without the sanction of the constituted authority.

The Lord, indeed, had told His disciples to carry a sword; but He did not tell them to use it. But that after this sin Peter should become a pastor of the Church was no more improper than that Moses, after smiting the Egyptian, should become the leader of the congregation. In both cases the trespass originated not in inveterate cruelty, but in a hasty zeal which admitted of correction. In both cases there was resentment against injury, accompanied in one case by love for a brother, and in the other by love, though still carnal, of the Lord. Here was evil to be subdued or rooted out; but the heart with such capacities needed only, like good soil, to be cultivated to make it fruitful in virtue.
