What Does the Church Teach About Contraception and Natural Family Planning?

The Teaching Everyone Has Heard Of

Even people who know almost nothing about the Catholic Church usually know one thing: Catholics are not supposed to use contraception. Many assume this means the Church wants couples to have as many children as possible, whatever the circumstances.

That is not what she teaches. The Church does teach that contraception is morally wrong. But she also teaches responsible parenthood, and permits couples, for good reasons, to space births or avoid pregnancy by natural means (CCC 2366–2372).

Where the Teaching Comes From

Opposition to contraception was the common teaching of all Christian churches until 1930, when the Anglican Communion first allowed it in limited cases. Other Protestant bodies soon followed.

The Catholic Church held firm. When the contraceptive pill appeared in the 1960s, many expected her teaching to change. Instead, in 1968, Pope St Paul VI restated it in his encyclical Humanae Vitae. Every pope since has confirmed it, and it is taught in the Catechism today (CCC 2370).

The Heart of the Teaching

The Church’s reasoning starts not with rules but with what marriage and the marital act are for.

In marriage, sexual union has two inseparable meanings (CCC 2366; Humanae Vitae 12):

The unitive meaning: it expresses and deepens the total, faithful love of husband and wife.
The procreative meaning: it is open to the gift of new life.

God has joined these two meanings together, and the Church teaches that it is wrong for us deliberately to separate them. Every marital act must remain open to the transmission of life (CCC 2366).

Marriage involves a total gift of self. Contraception, the Church teaches, introduces a holding back into that gift. In effect, it says, “I give you all of myself, except my fertility.” St John Paul II described this as a falsification of the inner truth of married love, which is meant to be a complete self-giving (CCC 2370).

What Counts as Contraception?

The Catechism defines contraception as any action which, whether in anticipation of the marital act, during it, or afterwards, is specifically intended to prevent procreation (CCC 2370; Humanae Vitae 14).

This includes the pill, condoms, IUDs, and sterilisation done for contraceptive purposes. Some methods, such as certain pills and IUDs, may also act after conception has occurred, which raises the further and graver issue of ending an early human life.

Responsible Parenthood

The Church does not ask couples to have children without thought. She asks them to be generous and responsible.

Couples may have just reasons for spacing births or avoiding pregnancy, for a time or even indefinitely: health problems, financial hardship, psychological strain, or other serious circumstances (CCC 2368). The Church does not list every possible reason. She leaves it to the couple to discern prayerfully, before God, with honesty and generosity.

What matters is not only whether they avoid pregnancy, but how.

Natural Family Planning

Natural family planning (NFP) means the methods by which a couple identifies the fertile and infertile times in a woman’s cycle, using natural signs. If they have a just reason to avoid pregnancy, they abstain from intercourse during the fertile time. If they hope to conceive, they can use the same knowledge to help them.

Modern NFP is not the old “rhythm method” of guessing from the calendar. It is based on careful observation of signs in the woman’s body, and when learned properly and followed carefully, modern methods are highly effective. Well-known methods include:

The Billings Ovulation Method, developed by Drs John and Evelyn Billings in Melbourne in the 1950s and 1960s;
The Creighton Model;
The sympto-thermal method, which combines several signs;
The Marquette Method, which uses a fertility monitor.

Couples should learn from a qualified instructor.

Isn’t NFP Just Catholic Contraception?

This is the most common objection, and it deserves a straight answer.

The goal may sometimes be the same: avoiding pregnancy. But the means are morally different. With contraception, a couple has intercourse and acts to make it infertile. With NFP, a couple does nothing to alter the marital act. They simply choose not to have intercourse at a time when it might lead to conception.

An analogy: a farmer who does not want a crop from a field this season can simply leave it unsown. Or he can sow it and then poison the seed. The result is the same empty field, but the two acts are plainly different. One respects the nature of what he is doing; the other works against it.

NFP also requires something contraception does not: periodic abstinence. That calls for communication, self-control and mutual respect. Many couples who practise NFP say it has deepened their marriage. Of course, NFP can be misused too, if a couple uses it selfishly, with no serious reason. The Church asks for honesty about motives as well as methods.

A Hard Teaching

The Church knows this teaching is difficult for many couples. Many Catholics struggle with it, and many have never had it properly explained.

If you have used contraception, the Church’s answer is not condemnation but invitation. Bring it to Confession, learn about NFP, and talk it through with a good priest. God’s grace is given for exactly this kind of struggle.

A Vision of Love

Humanae Vitae is often remembered only for its “no.” But Paul VI’s encyclical is above all a vision of married love as fully human, total, faithful and fruitful. The teaching on contraception is the Church’s way of protecting that vision.

The Church believes that marriage is a gift from God, that children are its supreme gift (CCC 2378), and that love which is given completely is love at its most beautiful.
