Matrimonial Consent
The free, full, and irrevocable consent of both spouses is the indispensable element that "makes the marriage." No human power can replace it.
CCC 1625–1637
Key Points
The central teachings from this section of the Catechism.
The parties to a marriage covenant must be free to marry: free from coercion, free from any natural or Church law impediment. The Church holds that without free consent, there is no marriage. No human power can substitute for this consent.
The essential act that makes a marriage is the irrevocable consent of both spouses. They mutually give and accept each other, saying "I take you to be my wife / husband." This consent is an act of the will by which each partner freely gives themselves entirely to the other.
The Church requires that marriage be celebrated in a specific canonical form: in the presence of the priest or deacon and at least two witnesses. This requirement protects the public character of marriage and ensures the consent is truly free and the act is valid.
A mixed marriage (Catholic with a baptized non-Catholic) requires express permission. Marriage with disparity of cult (Catholic with an unbaptized person) needs a dispensation. Both present challenges but can bear fruit if the couple shares what they have received from their communities.
From the Catechism
"The consent must be an act of the will of each of the contracting parties, free of coercion or grave external fear. No human power can substitute for this consent. If this freedom is lacking the marriage is invalid."
— CCC 1628
"The Church holds the exchange of consent between the spouses to be the indispensable element that 'makes the marriage.' If consent is lacking there is no marriage."
— CCC 1626
"Differences about faith and the very notion of marriage, but also different religious mentalities, can become sources of tension in marriage, especially as regards the education of children. The temptation to religious indifference can then arise."
— CCC 1634
Scripture
"From the beginning of creation, God made them male and female. For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. . . . What therefore God has joined together, let not man put asunder."
"I appeal to you therefore, brethren, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship."
"For the unbelieving husband is consecrated through his wife, and the unbelieving wife is consecrated through her husband."
Common Questions
Three elements are essential: the free consent of both parties, the absence of impediments, and the proper canonical form (celebrated before a priest or deacon and two witnesses). If any of these is lacking, the marriage may be declared invalid through the annulment process.
Yes, but with conditions. Marriage with a baptized non-Catholic (mixed marriage) requires express permission from the bishop. Marriage with an unbaptized person (disparity of cult) requires a formal dispensation. In both cases, the Catholic party promises to do all in their power to raise children Catholic.
Absolutely not. The Catechism is emphatic that freedom from coercion is essential. If consent is given under grave fear or external pressure, the marriage is invalid. The Church's marriage preparation process specifically verifies that both parties are entering the marriage freely.
Free consent is the heart of the marriage covenant. The Church safeguards this freedom through canonical form, preparation, and pastoral care — ensuring every marriage is entered freely and with full understanding.
