On Marriage and Concupiscence

“By your new mode of controversy,” says he, “you both profess to be a catholic and patronize Manichæus, inasmuch as you designate matrimony both as a great good and a great evil.” Now he is utterly ignorant of what he says, or pretends to be ignorant. Or else he does not understand what we say, or does not wish it to be understood. But if he does not understand, he is impeded by the pre-occupation of error; or if he does not wish our meaning to be understood, then obstinacy is the fault with which he defends his error. Jovinian, too, who endeavoured a few years ago to found a new heresy, used to declare that the Catholics patronized the Manicheans, because in opposition to him they preferred holy virginity to marriage. But this man is sure to reply, that he does not agree with Jovinian in his indifference about marriage and virginity. I do not myself say that this is their opinion; still these new heretics must allow, by the fact of Jovinian's playing off the Manicheans upon the Catholics, that the expedient is not a novel one. We then declare that marriage is a good, not an evil. But just as the Arians charge us with being Sabellians, although we do not say that the Father, and the Son, and the Holy Ghost are one and the same, as the Sabellians hold; but affirm that the Father, and the Son, and the Holy Ghost have one and the same nature, as the Catholics believe: so do the Pelagians cast the Manicheans in our teeth, although we do not declare marriage to be an evil, as the Manicheans pretend, but affirm that evil accrued to the first man and woman, that is to say, to the first married pair, and from them passed on to all men, as the Catholics hold. As, however, the Arians, while avoiding the Sabellians, fall into worse company, because they have had the audacity to divide not the Persons of the Trinity, but the natures; so the Pelagians, in their efforts to escape from the pestilent error of the Manicheans, by taking the opposite extreme, are convicted of entertaining worse sentiments than the Manicheans themselves touching the fruit of matrimony, inasmuch as they believe that infants stand in no need of Christ as their Physician.
