It is important to make clear the relationship between the practice of the virtues of purity, chastity and modesty, that is the living of the truth regarding human sexuality and human life, and the practice of justice. Respect for human life is related essentially to respect for the integrity of marriage and the family. The attack on the innocent and defenseless life of the unborn has its origin in an erroneous view of human sexuality, which attempts to eliminate, by mechanical or chemical means, the essentially procreative nature of the conjugal act. This error maintains that the artificially altered act retains its integrity. The claim is that the act remains unitive or loving, even though the procreative nature of the act has been radically violated. In fact, it is not unitive, for one or both of the partners withholds an essential part of the gift of self, which is the essence of the conjugal union. The so-called “contraceptive mentality” is essentially anti-life. Many forms of what is called contraception are in fact abortifacient, that is, they destroy a life which has already been conceived, has already begun.
