Contraception and Onanism
Contraception
Contraception.—Contraception in all its forms (onanism, condonism, vaginal irrigation, spermatocide) is a grave crime.
(a) It is an Injury to God.—Marriage was instituted by God to propagate the human race (Gen., i. 27, 28) and to bless homes with children (Ps., cxxvi, cxxvii), and He has made it a sacred institution and a Sacrament. Contraception defeats the ends of marriage and degrades it to the level of a mere instrument of carnal gratification. The hatred of God for this sin appears in general from the horror with which Scripture speaks of unnatural lust, and in particular from the case of Onan, whose sin is called detestable and whom God slew in punishment (Gen., xxxviii. 10).
(b) It is an Injury to Society.—The perpetuation of the human race is endangered as soon as marriage is abused as to its natural end. Hence, after the crime of homicide which destroys human life already in existence, contraception seems to rank next in enormity, since it prevents human life from coming into existence. This vice spreads moral degeneracy and decay from the home itself, and is rightly called race-suicide, since it depopulates and destroys the nation by the act of its own people.
(c) It is an Injury to the Family.—The happiness and success of the home depend chiefly on the respect which its members have one for the other and on the cultivation of the sturdy virtues that strengthen character. The husband and wife who practise onanism or other similar carnal vices cannot have the mutual respect they should have; the wife is deprived of the treasure of her modesty and is treated as a prostitute rather than as an honored wife and mother, and the husband is brutalized by the removal of the natural restraint to his sex passion. Such self-indulgent persons will either selfishly neglect the one or two children they may have, or will spoil them for life by the luxury and laziness in which they are reared.
(d) It is an Injury to the Individual.—As concerns the body, there is a perversion of the sex act from its definite use and specific end, and hence contraception has been described as “reciprocal masturbation.” As regards the soul, its higher goods of will and intellect are subordinated by the contraceptionist to the delight of passion, the lower impulses are greatly strengthened and self-control made more and more difficult, and the spiritual objectives that should prompt a rational creature are sacrificed for the passing gratification that moves the beasts.
