Outlines the Church's position on the question of sex in language enriched by modern psychology and sociology. The author shows that Christ's teachings are universal and eternal--not limited to a particular society at a certain time. Developing the theme of procreation through love as the essential and divine meaning of the sexual act, the author leads us to the Church's positive teaching on sex. The contemporary social problems connected with sex are faced in an unambiguous, realistic manner. Overpopulation, sexual deviation, the breakdown of marriages, sexual neuroses and frustration--all these distortions of the social fabric are related to Christian solutions. The author uses every means to point up the problems, even citing such modern and controversial authorities as Freud, Jung and Kinsey. Christian love is the healthiest solution for the control of the sexual passions and one sovereign way society may heal its moral wounds.
