"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. The error maintains that the artificially altered conjugal 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 so-called contraception are, in fact, abortifacient, that is, they destroy, at its beginning, a life which has already been conceived."
