Catholic Teaching

The Church describes marriage as a covenant between a man and a woman, ordered to the good of the spouses and to the procreation and education of children. The Catechism of the Catholic Church 1601–1605 sets this out as part of God’s plan from creation, not as a later rule added on top of it.

Children, in that light, are received as a gift rather than produced as an outcome. The Catechism 2366 speaks of fruitfulness as a gift and an end of marriage, so that the marital act keeps its openness to the transmission of life.

Humanae Vitae

Humanae Vitae 11–12 teaches that each marital act remains ordered to the transmission of life, and that the unitive and procreative meanings of the act are not to be separated. Paragraph 16 then addresses couples with just reasons to space births and treats their recourse to the infertile periods of the cycle as morally legitimate.

The Catechism

The Catechism 2370 draws the distinction this way, in paraphrase: periodic continence and methods based on self-observation of fertility respect the bodies of the spouses and the meaning of the act, while contraception deliberately withholds that openness. The difference is not a matter of technique but of what the act is allowed to say.

Familiaris Consortio

Familiaris Consortio 28–35, in its treatment of the family serving life, develops the same point at length, and paragraph 32 argues that contraception and recourse to the natural rhythms rest on two irreconcilable understandings of the person and of sexuality. This site describes the methods themselves on the Natural Family Planning page.

A judgment that belongs to the spouses

Gaudium et Spes 50 says that the judgment about how many children to have belongs to the spouses themselves, made before God, and that no one else can make it for them. The same paragraph is clear that this judgment is not simply private preference: it is formed with docility toward the teaching of the Church.

A conscience that is formed

Familiaris Consortio 32 insists that this discernment be an honest one, and that the couple’s conscience needs formation rather than mere sincerity. Amoris Laetitia 222 speaks of accompanying couples in forming that conscience in their decisions about having children, including in the use of methods based on the natural rhythms.

Amoris Laetitia 80–85 sets the same discussion inside marriage understood as a communion of life and love, and not only as a means to children. Read Responsible Parenthood for how this works out in practice.

The Church’s pastoral documents speak in the language of accompaniment and mercy: couples are met where they are, invited rather than pressured, and helped to take the next step they can actually take. Amoris Laetitia in particular asks pastors and ministries to walk with families patiently.

That is the spirit intended here. If you are in a difficult situation, or if what you read on this site does not seem to fit your life, the right next step is a conversation and not a verdict. Your parish priest can offer that in person, and you are also welcome to write to the program.

This page is a summary written by a lay ministry. It is not a Church document, it carries no magisterial authority, and it cannot settle a question for your conscience. Where this site’s wording and a Church document differ, the document is what counts.

So please read the originals linked below, and bring the questions that matter to your parish priest, who knows your situation and can answer you in person.
