But contraceptives allow for recreational sex. 13 Contraception launches people on a lifestyle which makes abortion more likely, not less likely, to be chosen. So perhaps we need more effective, non-abortifacient contraceptives. They allow a devaluation of human life by stripping the life-giving power away from the sexual act. Sex can then become a meaningless game, rather than the profound mystery that arises out of the deep unity of the couple permanently committed to each other, sharing in God's power to create new life.
Contraception turns the sexual act against life, against the very power that makes it so meaningful.
By changing the nature of the sexual act, it also changes the relationship of the couple involved. By holding back their fertility from each other, the couple dehumanizes themselves and each other, and their relationship. It becomes very easy for them to simply use each other for their own pleasure. This is a terrible degradation of their own humanity and something most of us instinctively rebel against. It is no surprise, then, that when people learn to degrade and devalue themselves, their loved one, and their relationship, that it becomes easy to devalue the new life that comes forth from them.
