I. CATHOLIC TEACHING ABOUT MARRIAGE AND THE REGULATION OF BIRTHS
WHAT DOES THE CATHOLIC CHURCH TEACH ABOUT THE RELATIONSHIP OF MARRIAGE?
Marriage is a permanent relationship created by God and entered into by
the free consent of man and woman. It is a relationship of love and
service, and it is a Christian sacrament.
"The intimate partnership of married life and love has been established by
the Creator and qualified by His laws. It is rooted in the conjugal
covenant of irrevocable personal consent.. .
"By that human act whereby spouses mutually bestow and accept each other,
a relationship arises which by divine will and in the eyes of society too
is a lasting one . . . A man and a woman, who by the marriage convenant of
conjugal love 'are no longer two, but one flesh' (Mt 19:6), render mutual
help and service to each other through an intimate union of their persons
and of their actions ... Christian spouses have a special sacrament by
which they are fortified and receive a kind of consecration in the duties
AND DIGNITY OF THEIR STATE" (GAUDIUM ET SPES, 48).[1]
WHAT DOES THE CHURCH SAY ABOUT METHODS OF BIRTH CONTROL?
"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 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. Relying on these principles, sons of the Church may not
undertake methods of regulating procreation which are found blameworthy by
the teaching authority of the Church in its unfolding of the divine law"
(Gaudium et Spes, 51).
Does the Church teach that the unnatural or artificial means of birth
control are immoral and blameworthy? Yes. In Humanae Vitae, the
first-named form of illicit or unnatural method of birth control is
abortion (n. 14).[3]
Then, "equally to be excluded, as the teaching authority of the Church has
frequently declared, is direct sterilization, whether perpetual or
temporary whether of the man or woman" (Humanae Vitae, 14). This condemns
tubal ligations, vasectomies, and the Pill.
"Similarly excluded is 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" (Humanae Vitae, 14). Such unnatural forms include
the Pill, the intrauterine device, foams, diaphragms, condoms, withdrawal,
mutual or solitary masturbation and sodomistic practices.
Are some forms of unnatural birth control worse than others? Yes. Those
forms that act after conception has occurred to prevent the continuation
of the pregnancy participate in the additional evil of abortion. "From the
moment of its conception life must be guarded with greatest care, while
abortion and infanticide are unspeakable crimes" (Gaudium et Spes, 51).
Surgical abortion is the most obvious but not the only form. The
intrauterine device (IUD) acts primarily as an early abortion agent by
preventing implantation of the week-old human life.
The birth control Pill makes the inner lining of the uterus very hostile
to implantation. It is not known how often the Pill acts in this way, but
it cannot be denied that the Pill may be acting as an early abortion agent
in any given cycle in any given woman.[4]
