Contraception.
The following is a summary of what Pope Paul VI said in Humanae Vitae would happen with the rise of contraception as explained by Janet Smith, professor of philosophy at the University of Dallas:
Pope Paul VI made four rather general “prophecies” about what would happen if the Church’s teaching on contraception were ignored.
1. Irresponsibility Rewarded
There is no question that contraception is behind much of this trouble. Contraception has made sexual activity a much more popular option that it was when the fear of pregnancy deterred a great number of young men and women from engaging in premarital sexual intercourse. The availability of contraception has led them to believe that they can engage in premarital sexual activity “responsibly.” But teenagers are about as responsible in their use of contraception as they are in all other phases of their lives—such as making their beds, cleaning their rooms and getting their homework done on time.
2. Loss of Respect for Women
Paul VI also argued that “the man” will lose respect for “the woman” and “no longer (care) for her physical and psychological equilibrium” and will come to “the point of considering her as a mere instrument of selfish enjoyment and no longer as his respected and beloved companion.” This concern reflects what has come to be known as a “personalist” understanding of morality. The personalist understanding of wrongdoing is based upon respect for the dignity of the human person. The Pope realized that the Church’s teaching on contraception is designed to protect the good of conjugal love. When spouses violate this good, they do not act in accord with their innate dignity and thus they endanger their own happiness. Treating their bodies as mechanical instruments to be manipulated for their own purposes, they risk treating each other as objects of pleasure.
3. Abuse of Power
Paul VI also observed that the widespread acceptance of contraception would place a “dangerous weapon . . . in the hands of those public authorities who take no heed of moral exigencies.” The history of the family-planning programs in the Third World is a sobering testimony to this reality. In Third World countries many people undergo sterilization unaware of what they are doing. The forced abortion program in China shows the stark extreme toward which governments will take population programs. Moreover, few people are willing to recognize the growing evidence that many parts of the world face not overpopulation, but underpopulation. It will take years to reverse the “anti-child” mentality now entrenched in many societies.
4. Misuse of the Body
Pope Paul’s final warning was that contraception would lead man to think that he had unlimited dominion over his own body. Sterilization is now the most widely used form of contraception in the U.S.; individuals are so convinced of their rights to control their own bodies that they do not hesitate to alter even their own physical make-up.
The desire for unlimited dominion over one’s own body extends beyond contraception. The production of “test-tube babies” is another indication of the refusal to accept the body’s limitations; so too are euthanasia and the use of organs transplanted from those who are “nearly” dead. We seek to adjust the body to our desires and timetables, rather than adjusting ourselves to its needs.
