The Catholic Wisdom — What Canon Law Says About Getting Married
Catholic Wisdom Series
What Is the Code of Canon Law?
The Code of Canon Law (1983) is the Church’s legal framework for her life and governance — 1,752 canons across seven books. Pope John Paul II promulgated it as the renewal of Church discipline after Vatican II. Canons 1055–1165 govern marriage specifically, covering everything from consent and impediments to the canonical form required for a valid wedding.
Why It Matters for Dating and Marriage
I learned the hard way that most Catholics treat canon law as bureaucratic fine print — something you deal with when a priest hands you a pre-Cana packet. That’s backwards. Canon law on marriage isn’t red tape; it’s the Church protecting what marriage actually is. Canon 1055 defines marriage as a covenant, not a contract — a total, permanent, faithful, and fruitful union ordered to the good of spouses and the generation of children. Understanding that before you’re engaged changes how you date.
One Teaching We Use Every Day
“The matrimonial covenant, by which a man and a woman establish between themselves a partnership of the whole of life, is by its nature ordered toward the good of the spouses and the procreation and education of offspring.” (Code of Canon Law, Canon 1055 §1)
The phrase “partnership of the whole of life” is doing a lot of work. Not a partnership of feelings, not of convenience — of the whole of life. That’s what you’re moving toward if you’re dating with real intent. Once you absorb that, casual relationships that were never going anywhere lose their appeal.
Lack of Freedom — What Tribunals Actually See
Most marriages the Church later declares null don’t fail on paperwork. They fail on consent. The Catechism puts it plainly: “The consent must be an act of the will of each of the contracting parties, free of coercion or grave external fear... If this freedom is lacking the marriage is invalid.” Canon 1095 codifies the same reality — if a person lacks the discretion of judgment or the psychic capacity to assume the essential obligations of marriage, the consent never landed.
Here’s what we watch for in dating, long before anyone is talking about a ring:
Active addiction running the show. Pornography, alcohol, substances, gambling — while the addiction is in charge, the person isn’t free to promise fidelity or self-gift. The honest answer is treatment first, vows later.
Untreated mental illness with no insight. Not the diagnosis itself — the refusal to address it. A person who won’t name what’s happening or accept help can’t freely give what they haven’t yet faced.
Profound immaturity. Can’t hold a job. Can’t keep a small commitment. Panics every time something asks for a binding “yes.” The capacity for a lifelong “yes” hasn’t been formed yet.
A “yes” given under pressure. Family expectations, an unexpected pregnancy, sunk-cost panic, the venue is already booked. Pressure produces a wounded yes, and a wounded yes may be no consent at all.
A hidden double life. The person you’re dating isn’t the person you’d be marrying. Consent given to a mask is consent given to no one.
None of these are forever-disqualifications. They’re formation work the Church expects you to do before the altar, not after.
Lack of Form — Why the Church Cares Where You Marry
The other ground tribunals see constantly is simpler: lack of canonical form. Canon 1108 requires that a Catholic marry in the presence of a properly delegated priest or deacon and two witnesses, in the Church’s form, unless the local bishop grants a dispensation. Canon 1117 makes clear that a Catholic is bound by this even if they’ve drifted from practice. So the Catholic who marries on a beach with a college roommate officiating isn’t living in a “less-than-ideal” marriage — canonically, no marriage took place.
This isn’t the Church being precious about real estate. It’s the Church saying that how and where you marry is a public statement about what marriage actually is. If you’re dating a Catholic who shrugs at the form question, you’re not having a logistics disagreement. You’re having a disagreement about the thing itself.
How We Apply It
In True Love (Young Adults 20-39): We teach young adults to read freedom and form backwards into dating. If something would later be grounds for nullity, that’s the formation work to do now — not after vows.
In Before Forever (High School 14-19): We bring parents into the freedom conversation early. Most teenagers can’t yet name what makes a “yes” free, but they can be formed in the habits — honesty, follow-through, treatment when it’s needed — that will make a real yes possible later.
FAQ
Q: So if my future spouse has a mental illness, can we not get married? A: That’s not what the Church is saying. Canon 1095 is about capacity at the moment of consent — whether the condition is being addressed, whether there’s insight, whether the essential obligations of marriage can actually be assumed. Treatment and formation before vows is exactly the point.
Q: Why would canon law be relevant to someone who’s just dating? A: Because you date toward something. If marriage is the destination, knowing what the Church requires for a valid marriage — real freedom, no impediments, proper form — shapes how seriously you take the relationship you’re building right now.
