In an Integral Vision of the Human Person and of His or Her Vocation

32. In the context of a culture which seriously distorts or entirely misinterprets the true meaning of human sexuality, because it separates it from its essential reference to the person, the Church more urgently feels how irreplaceable is her mission of presenting sexuality as a value and task of the whole person, created male and female in the image of God.

In this perspective the Second Vatican Council clearly affirmed that "when there is a question of harmonizing conjugal love with the responsible transmission of life, the moral aspect of any procedure does not depend solely on sincere intentions or on an evaluation of motives. It must be determined by objective standards. These, based on the nature of the human person and his or her acts, preserve the full sense of mutual self-giving and human procreation in the context of true love. Such a goal cannot be achieved unless the virtue of conjugal chastity is sincerely practiced."(85)

It is precisely by moving from "an integral vision of man and of his vocation, not only his natural and earthly, but also his supernatural and eternal vocation,"(87) that Paul VI affirmed that the teaching of the Church "is founded upon the inseparable connection, willed by God and unable to be broken by man on his own initiative, between the two meanings of the conjugal act: the unitive meaning and the procreative meaning."(88) And he concluded by re-emphasizing that there must be excluded as intrinsically immoral "every action which, either in anticipation of the conjugal act, or in its accomplishment, or in the development of its natural consequences, proposes, whether as an end or as a means, to render procreation impossible."(89)

When couples, by means of recourse to contraception, separate these two meanings that God the Creator has inscribed in the being of man and woman and in the dynamism of their sexual communion, they act as "arbiters" of the divine plan and they "manipulate" and degrade human sexuality-and with it themselves and their married partner-by altering its value of "total" self-giving. Thus the innate language that expresses the total reciprocal self-giving of husband and wife is overlaid, through contraception, by an objectively contradictory language, namely, that of not giving oneself totally to the other. This leads not only to a positive refusal to be open to life but also to a falsification of the inner truth of conjugal love, which is called upon to give itself in personal totality.

When, instead, by means of recourse to periods of infertility, the couple respect the inseparable connection between the unitive and procreative meanings of human sexuality, they are acting as "ministers" of God's plan and they "benefit from" their sexuality according to the original dynamism of "total" selfgiving, without manipulation or alteration.(90)

In the light of the experience of many couples and of the data provided by the different human sciences, theological reflection is able to perceive and is called to study further the difference, both anthropological and moral, between contraception and recourse to the rhythm of the cycle: it is a difference which is much wider and deeper than is usually thought, one which involves in the final analysis two irreconcilable concepts of the human person and of human sexuality. The choice of the natural rhythms involves accepting the cycle of the person, that is the woman, and thereby accepting dialogue, reciprocal respect, shared responsibility and self- control. To accept the cycle and to enter into dialogue means to recognize both the spiritual and corporal character of conjugal communion and to live personal love with its requirement of fidelity. In this context the couple comes to experience how conjugal communion is enriched with those values of tenderness and affection which constitute the inner soul of human sexuality, in its physical dimension also. In this way sexuality is respected and promoted in its truly and fully human dimension, and is never "used" as an "object" that, by breaking the personal unity of soul and body, strikes at God's creation itself at the level of the deepest interaction of nature and person.
