What does the Church teach about sexuality?
The short answer
The Church teaches that sexuality is a good and beautiful gift from God, woven into what it means to be human and made to express total, faithful, life-giving love. Its proper home is the lifelong commitment of marriage between a man and a woman. The virtue that lets us live our sexuality with freedom and integrity, in every state of life, is chastity.
Full explanation
It's worth saying clearly up front, because it surprises people: the Church does not think sex is dirty or shameful. Quite the opposite. She teaches that God made us as embodied, sexual persons, male and female, and called all of it "very good." Our capacity to give and receive love through our bodies is part of God's design, not a flaw to be ashamed of. The teaching that follows isn't about suppressing this gift but about honouring it enough to use it well.
The key idea is that sexuality is a kind of language — and like any language, it can be spoken truthfully or it can lie. The physical union of two people "says" something enormous: I give you all of myself, holding nothing back, for good. That's why the Church holds that this language belongs within marriage, where that total, permanent, faithful self-gift is actually being made. Outside of that commitment, the body promises a totality the heart hasn't yet given. The Church's vision isn't "rules against pleasure"; it's an insistence that the body tell the truth about love.
This is also why the Church links sexuality so closely with openness to new life. In God's design, the love that unites a husband and wife is the same love from which children come — the two are not meant to be cut apart. Married love is meant to be both unitive (binding the couple) and procreative (open to life), and these two meanings belong together. That conviction shapes the rest of the Church's teaching on sexual matters.
The virtue that makes all of this livable is chastity — a word that has been badly misunderstood. Chastity is not the same as never having sex; it is not a synonym for repression or frigidity. It is the integration of our sexuality into the whole person, so that desire is governed by love rather than ruling us. Everyone is called to chastity, lived differently according to their state in life: a married couple lives it through faithfulness to each other, a single or consecrated person through self-mastery and a love expressed in other ways. Chastity, rightly understood, is a form of freedom — the strength to love people as persons rather than to use them.
Finally, the Church teaches all of this knowing how hard it is, and how much pain surrounds this area of life. Everyone struggles here in some way, and the Gospel meets that struggle not with contempt but with mercy. The call to chastity is held out as a path of growth and healing, walked with grace and patience, never as a test most people simply fail. The aim is not condemnation; it is helping people love truly and become whole.
Why this matters
How we treat sexuality shapes how we treat people. When the body's language of self-gift is honoured, sex becomes a place of trust, faithfulness, and life. When it is severed from commitment, people are more easily used, discarded, and wounded — something a glance at the modern landscape of heartbreak makes painfully clear. The Church's teaching, far from being anti-body, is a defence of the body's dignity and of the person as someone to be loved, never merely used. Lived out, it protects against both shame and exploitation.
Myth Common misunderstanding
The biggest misunderstanding is that the Church is "anti-sex" or thinks of the body as something dirty. In fact she teaches that the body and sexuality are profoundly good gifts from God — so good that they deserve to be treated with reverence rather than spent carelessly. The teaching is restrictive only in the way that any deep love is "restrictive": it asks for faithfulness and totality because that is what real self-gift requires.

Where might honouring your body — and other people's — as something for genuine love rather than use change the way you think about a relationship in your life?
