Anti-pelagian Writings by St. Augustine
Chapter 43 [XXXVIII.]--Human Offspring, Even Previous to Birth, Under Condemnation at the Very Root. Uses of Matrimony Undertaken for Mere Pleasure Not Without Venial Fault.
Where God did nothing else than by a just sentence to condemn the man who wilfully sins, together with his stock; there also, as a matter of course, whatsoever was even not yet born is justly condemned in its sinful root. In this condemned stock carnal generation holds every man; and from it nothing but spiritual regeneration liberates him. In the case, therefore, of regenerate parents, if they continue in the same state of grace, it will undoubtedly work no injurious consequence, by reason of the remission of sins which has been bestowed upon them, unless they make a perverse use of it, -- not alone all kinds of lawless corruptions, but even in the marriage state itself, whenever husband and wife toil at procreation, not from the desire of natural propagation of their species, but are mere slaves to the gratification of their lust out of very wantonness. As for the permission which the apostle gives to husbands and wives, |not to defraud one another, except with consent for a time, that they may have leisure for prayer,| he concedes it by way of indulgent allowance, and not as a command; but this very form of the concession evidently implies some degree of fault. The connubial embrace, however, which marriage-contracts point to as intended for the procreation of children, considered in itself simply, and without any reference to fornication, is good and right; because, although it is by reason of this body of death (which is unrenewed as yet by the resurrection) impracticable without a certain amount of bestial motion, which puts human nature to the blush, yet the embrace is not after all a sin in itself, when reason applies the concupiscence to a good end, and is not overmastered to evil.
