The Theses

I. Impotence for intercourse, if it is perpetual, constitutes a diriment impediment to marriage (61) - p. 61.

II. Impotence for generation, if it alone is present, does not constitute a diriment impediment to marriage (61-69) - p. 62.

Absolute and perpetual virginity, considered in itself, is by far to be preferred to the common condition of married life; insofar as it is referred to God, however, it contains an eminent act of homage (145-149) - p. 137.

There is no special virtue of virginity, since virginity merely perfects chastity intrinsically or extrinsically, and therefore is not distinguished from chastity itself, or from the virtue from whose motive virginity is cultivated (150-153) - p. 146.

Nature is by no means offended by perpetual celibacy (166) - p. 157.

Although a woman who has given birth through fornication possesses a title to greater indulgence toward herself in her very motherhood, and illegitimate offspring ought not to be punished with a penalty properly so called, nevertheless the law of the mutual sharing of honor and ignominy, founded in nature and most salutary, demands that this woman and her offspring consequently occupy a humbler place in civil society (167) - p. 158.

The onanistic use of marriage is intrinsically and gravely evil (257-270) - p. 254.

Complete pleasure sought or admitted separately by a spouse, in either sex, adds to the malice of pollution a grave malice against justice or against the sacrament (278) - p. 274.

The grave danger of pollution being excluded, some incomplete solitary acts are simply morally good, while others at least cannot be gravely blamed in spouses (280-284) - p. 275.

Every fornication is a mortal sin, even when considered by the natural law alone (304-312) - p. 291.

Every voluntary pollution, indeed every full consent to accidental pollution, whether of the male or of the female, is infected with intrinsic and grave malice, and is specifically distinguished from imperfect lust (324-342) - p. 320.

Every venereal pleasure deliberately sought or admitted outside marriage is intrinsically and gravely evil (353-355) - p. 344.

Pollution which occurs apart from intention and without consent is gravely imputed only to him who foresaw it as sufficiently proximately connected with his sin of incomplete lust, or who, when it was then imminent, did not prevent it by ceasing from lust (374-375) - p. 357.
