487. VII. IN SUCH CASES ADULTERIES ARE MILD. This is manifest from what was said just above, n. 486, without further confirmation; for it is well known that the quality of every deed and in general the quality of every thing, depends upon circumstances, and which mitigate or aggravate it; but adulteries of this degree are mild at the first times of their commission; and also remain mild so far as the offending party of either sex, in the future course of life, abstains from them for these reasons;—because they are evils against God, or against the neighbour, or against the goods of the state, and because, in consequence of their being such evils, they are evils against reason; but on the other hand, if they are not abstained from for one of the abovementioned reasons, they are reckoned amongst grievous adulteries; thus it is according to the divine law, Ezek. xviii, 21, 22, 24, and in other places: but they cannot, from the above circumstances, be pronounced either blameless or culpable, or be predicated and judged as mild or grievous, because they do not appear before man, neither are they within the province of his judgement; wherefore it is meant, that after death they are so accounted or imputed.
488. VIII. ADULTERIES OF THE SECOND DEGREE ARE ADULTERIES OF LUST, WHICH ARE COMMITTED BY THOSE WHO INDEED ARE ABLE TO CONSULT THE UNDERSTANDING, BUT FROM ACCIDENTAL CAUSES AT THE MOMENT ARE NOT ABLE. There are two things which, in the beginning, with every man who from natural is made spiritual, are at strife together, which are commonly called the spirit and the flesh; and since the love of marriage is of the spirit, and the love of adultery is of the flesh, in such case there is also a combat between those loves. If the love of marriage conquers, it gains dominion over and subjugates the love of adultery, which is effected by its removal; but if it happens that the lust of the flesh is excited to a heat greater than what the spirit can control from reason, it follows that the state is inverted, and the heat of lust infuses allurements into the spirit, to such a degree, that it is no longer master of its reason, and thence of itself: this is meant by adulteries of the second degree, which are committed by those who indeed are able to consult the understanding, but by reason of accidental causes at the moment are not able. But the matter may be illustrated by particular cases; as in case a meretricious wife by her craftiness captivates
