The Catholic Church and Birth Control


300 - 1900 AD

Church leaders judged any form of birth control sinful.

Underlying reasons:
* The male sperm was considered to contain the future person. Spilling sperm equalled abortion.
* Following St Augustine, all sexual acts between partners were deemed sinful unless aimed at procreation.


In his Encyclical Casti Connubii Pope Pius XI forbids any form of artificial contraception.

"Any use whatsoever of matrimony exercised in such a way that the act is deliberately frustrated in its natural power to generate life is an offense against the law of God and of nature, and those who indulge in such are branded with the guilt of a grave sin."

1963 - 1966

The question of contraception was raised at the Second Vatican Council. Pope John XXII established an international commission of experts to study the question. Pope Paul VI extended the commission to 72 members from five continents. The commission concluded [with a majority of 68 to 4!] that artificial birth control was not intrinsically evil and that Catholic couples should be allowed to decide for themselves about the methods to be employed.

Pope Paul VI issues the Encyclical Humanae Vitae.

"Sterilization is to be condemned, as the magisterium of the Church has affirmed on many occasions, whether of the man or of the woman, whether permanent or temporary. Similarly excluded is any action which either before, at the moment of, or after sexual intercourse, is specifically intended to prevent procreation - whether as an end or as a means. [Nothing can justify] something which of its very nature contradicts the moral order . . . sexual intercourse which is deliberately contraceptive and so intrinsically wrong."


Humanae Vitae is implicitly or explicitly rejected by many in the Church.

* Bishops' Conferences tell their faithful they can, as a last resort, follow their own consciences. See extensive report on this by Joseph Selling.
* Theologians world wide express their disagreement. Full online report to follow.
* In educated countries 74% of Catholics ignore the Pope and use contraceptives. See the Response in the USA.
* Because of the official prohibition of birth control a large section of Catholics stops going to church. Full online report to follow.

1981 - now

The overwhelming majority of Catholics in educated countries use articificial means of birth control in spite of the official Vatican guidelines.

In the USA, for example, 98% (!) of all Catholic women of reproductive age who have ever had sex have used a method of contraception other than natural family planning. Among women who are currently at risk of unintended pregnancy, 87% of Catholics use contraception:
68% of them employ sterilization, an intra uterine device or the pill.
15% rely on condoms.
4% use other methods, such as withdrawal.
