The Catholic Church teaches that...

marriage is an original gift from God to humanity. Although sin entered the world damaging the marital relationship, this gift was not lost but redeemed by Christ and raised to a sacrament (see Eph 5: 28-32; see also Mt 19: 4-6). Sacred Scripture proclaims that God created humanity in "His image" as "male and female" (see Gn 1: 27). So unique is this relationship that the marital union makes of husband and wife "one flesh" (Gn 2: 24). Procreation, Scripture teaches, is a gift from God (Gn 1: 28). When spouses conceive new life, they participate in the Lord God's creative power. This is an awesome privilege and sacred responsibility!

Over the centuries and through the guidance of the Holy Spirit, the Catholic Church has reflected upon marriage, married love and the gift of life. Below you will find foundational documents that articulate these teachings.

Ecclesial Teaching

Second Vatican Council

  • Gaudium et Spes (Pastoral Constitution on the Church in the Modern World) 1965. One of the 16 documents composed at the Second Vatican Council, this pastoral constitution forms the core of the Church's teaching on the role of the Christian in modern society. Covering a broad range of political, social, economic, and theological topics, the Council fathers devote an entire section to marriage and the family.

    Gaudium et Spes excerpts


  • Pope Francis, Amoris Laetitia (The Joy of Love) April 8, 2016. This apostolic exhortation, "The Joy of Love," is the result of Pope Francis's prayerful reflection on the discussions and outcomes of two synods of bishops held in Rome in October 2014 and October 2015 on marriage and the family. In Amoris Laetitia, Pope Francis shares with the Church his teaching and encouragement regarding pastoral ministry to marriages and families, and the great vocation and mission that married couples and families are called to live out. For more about this document, visit our Amoris Laetitia page.
  • Deus Caritas Est (God is Love) 2005, Pope Benedict XVI. This papal letter (encyclical) reflects upon the cardinal virtue of love or Christian charity which is central to the whole of the Christian faith. While broadly teaching about love, the work is nevertheless applicable to all facets of the Christian life, including that of marriage.
  • Evangelium Vitae (The Gospel of Life) 1995, St. John Paul II. This encyclical teaches about the gift and value of human life. St. John Paul II describes modern threats to the value of life and urges all Christians to create a new culture of life, fostering a deeper appreciation and respect for all men and women. Included in the discussion of threats to human life is the subject of contraception which is described as "intrinsically evil." St. John Paul II draws a clear moral distinction between the immorality of contraception and the goodness of the methods of Natural Family Planning.
  • Gratissimam Sane (Letter to Families) 1994, St. John Paul II. Written during the Year of the Family, this letter is one of two key writings of St. John Paul II on the family (the other being Familiaris Consortio, see below) and contains many themes important to his pontificate. Main sections include: The Civilization of Love, which reflects on men, women, marriage, children, and society; and "The Bridegroom is with You," an extended meditation on marriage and family's place in the Scriptures, the life of Christ, and the Church.
  • "Theology of the Body" (1979-1984), St. John Paul II. "Theology of the Body" is the title given to a collection of talks (Papal Addresses) on God's design for human sexuality given over the course of five years. Appealing to the individual's experiences of truth, St. John Paul II discusses both Sacred Scripture and Catholic Tradition on the subject. This approach seeks not only to make understandable the rich theology of Catholic teaching on the nature of humanity created as man and woman, but also to communicate the truth and beauty of God's design of human sexuality. Included in this series is a substantial reflection on the papal encyclical, Humanae Vitae (Of Human Life) which treats married love and responsible parenthood. (For the content of the 139 Papal Addresses, see Catholic News Agency. Please note that the first Address is listed at the bottom of the list.)
  • Familiaris Consortio (The Role of the Christian Family in the Modern World) 1980, St. John Paul II. This apostolic exhortation addresses the place of the Christian family both in the Church and in the modern world. At the service of both life and love, the Christian family must seek its identity in the Divine Creator, participate in the mission of the Church, and work to effect change in society. Catholic teachings on marriage, conjugal love and responsible parenthood, and the methods of Natural Family Planning are also discussed.
  • Humanae Vitae (Of Human Life) 1968, St. Paul VI. This encyclical teaches about God's design for married love and the gift of life. The Holy Father teaches that the modern question about spacing and limiting births in marriage is important. It must, however, be considered within the context of God's design for married love. Married love is faithful, total, permanent, and fruitful. Its nature exists to create a "communion of persons" (the marriage) and to participate with God in bringing new life into the world (procreation). Included in the teaching is a discussion of the immorality of contraception, direct sterilization, and abortion (which are always intrinsically evil), and the morality of Natural Family Planning. Visit our Humanae Vitae page for additional resources, including audio, video, and prayer files.
  • Casti Connubii (On Christian Marriage) 1930, Pope Pius XI. This encyclical teaches about the virtue of chastity, specifically "marital chastity." The Holy Father includes a reflection on the threats to marriage and holds up God's will for marriage as the defense. The dignity of marriage and its spiritual benefits are also treated. The Holy Father encourages Christian couples to embrace the call of Christ in their daily lives.

The Holy See

  • Catechism of the Catholic Church 1997, This comprehensive treatment of the Church's teaching touches upon every facet of the Christian faith. This work is divided into four main sections: the profession of faith (the Creed), the celebration of the Christian mystery (the Liturgy), life in Christ (the moral life), and Christian prayer. While references to marriage and family can be found throughout the entire book, one may find paragraphs 1601-1666 and 2331-2400 to be particularly applicable.
  • Instrumentum Laboris, The Pastoral Challenges of the Family in the Context of Evangelization, III Extraordinary General Assembly, Synod of Bishops, 2014.

  • Vademecum for Confessors Concerning Some Aspects of the Morality of Conjugal Life 1997, Pontifical Council for the Family. Issued by the Pontifical Council for the Family, this brief document provides guidelines for the administration of the Sacrament of Reconciliation in difficult moral circumstances (particularly those of married life). Although addressed to confessors within the clergy, the document serves as a standard to guide all Christians in carrying out the call of Christ to live the virtue of chastity.
  • Ethics and Human Values in Family Planning 1988, Vatican Statement. Reprinted in The International Review of Natural Family Planning (Summer 1988). Submitted by the Vatican to XXII Council for the International Organizations of Medical Sciences, this statement notes that there are no value-free methods of family planning. It then lists six ethical challenges of contraception, drawing on examples. The document also explains that though the world sees a family planning crisis, the Church sees the real problem as one of ethics. (Note: The name of the Vatican Dicastery is not provided in this reprint.)
  • Donum vitae (Instruction on Respect for Human Life) 1987, Congregation for the Doctrine of the Faith. Published by the Congregation for the Doctrine of the Faith, this text is the predecessor to the above document, Dignitas personae. Written in the midst of significant medical innovation on assisted reproductive technology, this document defends the gift and dignity of human life (particularly in its earliest stages), against the onset of intrusive and immoral scientific innovation.
