Matrimony

Validity, consent, sacramentality, children, canonical form, divorce, separation, declarations of nullity, and what Catholic marriage actually promises.

The Catholic answer in about 30 seconds

Marriage is the covenant by which one man and one woman establish a partnership of the whole of life, ordered by its nature to the good of the spouses and the generation and education of children. Between baptized persons, a valid marriage is a sacrament. Consent makes marriage, but Catholics are also bound by canonical form unless legitimately dispensed and must be free of invalidating impediments. A declaration of nullity does not dissolve a valid bond; it judges that a valid marriage was not brought into being.

Make the case

Define the claim accurately, state the strongest fair objection, and use the evidence without shortcuts.

The covenant of marriage

Christ restores marriage to its creational meaning and raises the marriage of baptized persons to sacramental dignity.

Sources: Matthew 19:3–9 — Douay-Rheims; Ephesians 5:21–33 — Douay-Rheims; Catechism of the Catholic Church 1601–1666.

Consent and validity

The consent of persons capable of marriage, legitimately manifested, makes the marriage. Canonical impediments and form also matter for Catholics.

Sources: Code of Canon Law (1983), canons 1055–1057; canons 1083–1123.

Children and infertility

Marriage is ordered by nature to the generation and education of children, but infertility by itself neither prohibits nor invalidates marriage. The deliberate exclusion of an essential element of marriage can raise a different validity question.

Sources: Code of Canon Law (1983), 1055 §1; 1084 §3; 1101 §2.

Divorce, separation, and nullity

A ratified and consummated sacramental marriage cannot be dissolved by human power except death. Canon law also recognizes legitimate separation and civil recourse in appropriate circumstances, while a declaration of nullity concerns whether a valid bond existed from the start.

Sources: Code of Canon Law (1983), canon 1141; canons 1151–1155; canons 1671–1691; Catechism of the Catholic Church 1649; 2382–2386.

Place of celebration

Marriage location is governed by universal and particular law. Canon 1118 provides the universal Latin framework; diocesan policy determines many practical permissions.

Sources: Code of Canon Law (1983), canon 1118.

Use it in a real conversation

One claim. One distinction. One strong anchor.

1State the claim

Christian marriage is a lifelong covenant of one man and one woman, and between the baptized a valid marriage is sacramental.

2Clarify the distinction

Civil divorce, separation, nullity, and limited dissolution of certain non-sacramental bonds are not the same juridic or theological act.

3Anchor the evidence

Use Matthew 19, CIC 1055–1057 and 1141, and CCC 1601–1666.

Questions people actually ask

Every substantive answer carries direct source anchors.

What makes a valid marriage?

A valid marriage requires a man and woman capable of marriage, free consent, absence of invalidating impediments, and observance of canonical form when required. The spouses themselves confer the sacrament on each other in the Latin tradition.

Are children necessary?

Marriage is by nature ordered to the good of the spouses and the procreation and education of children. A marriage can be valid when children do not in fact result, but deliberately excluding the essential openness to children can invalidate matrimonial consent.

Sources: Code of Canon Law (1983), canon 1055 §1; canon 1084 §3; Catechism of the Catholic Church 1652–1654.

Discipline check: Latin-Church-universal; verified 2026-08-12.

Can we get married outdoors?

For Catholics in the Latin Church, marriage is ordinarily celebrated in a parish church when both parties are Catholic, or in a church or oratory when a Catholic marries another baptized Christian. The local ordinary can permit marriage in another suitable place. Particular diocesan law and policy can be more specific, so an outdoor wedding is not a universal entitlement.

Sources: Code of Canon Law (1983), canon 1118.

Discipline check: Latin-Church-universal; verified 2026-08-12.

Why was the word “obey” removed from the marriage vows?

The essential Catholic exchange of consent is not defined by the English word ‘obey.’ Marriage is a covenant of mutual self-gift, fidelity, permanence, and openness to children; liturgical wording can vary while preserving those essentials.

Sources: Order of Celebrating Matrimony, Questions before Consent and Form of Consent; Code of Canon Law (1983), canon 1057.

Discipline check: Latin-Church-universal; verified 2026-08-12.

Why can’t Catholics divorce and remarry?

A valid consummated sacramental marriage is indissoluble by any human power. Civil divorce can sometimes be tolerated for legal protection, but a person bound by a valid marriage cannot enter another union while the spouse lives.

Sources: Matthew 19:3–9 — Douay-Rheims; Code of Canon Law (1983), canon 1141; Catechism of the Catholic Church 1644–1651.

Discipline check: Latin-Church-universal; verified 2026-08-12.

What is an annulment?

An annulment is a declaration that a true matrimonial bond was invalid from the beginning because an essential element was lacking. It is not Catholic divorce and does not erase a real marriage that later failed.

Sources: Code of Canon Law (1983), canons 1671–1691; Catechism of the Catholic Church 1625–1632.

Reflect

A Catholic argument is stronger when it remains true after the other person states the hardest fair version of the objection.

Pray

Lord Jesus Christ, give us truth without arrogance, courage without hostility, and charity without compromise. Amen.
