By Matthew B. Rose, Catholic Exchange - Marital love has four aspects to it: freedom, totality, faithfulness, and fruitfulness (HV, 9); it has two purposes: the union of the spouses and the procreation of children (HV, 12). Rejecting one of those aspects or purposes, as artificial contraception does, violates the marital act, and is unacceptable; “each and every marital act must of necessity retain its intrinsic relationship to the procreation of human life” (HV, 11).
