Catholic Teaching on Marriage

The Catholic Church teaches today and has always and everywhere taught for 2000 years that marriage is the union of one man and one woman as husband and wife.

“Marriage is not just any relationship between human beings. It was established by the Creator with its own nature, essential properties and purpose. No ideology can erase from the human spirit the certainty that marriage exists solely between a man and a woman, who by mutual personal gift, proper and exclusive to themselves, tend toward the communion of their persons. In this way, they mutually perfect each other, in order to cooperate with God in the procreation and upbringing of new human lives.” [Congregation for the Doctrine of Faith, June 3, 2003]

This great truth about marriage is not some obscure doctrinal fine point but a fact of human nature, recognized from time immemorial by people of virtually every faith and culture. God made us male and female; only men and women cooperating in marital love together can truly become one flesh, and only marital unions further God’s purpose of creating new life that is welcomed, loved, nurtured and educated by their mother and father.

The Church teaches that man and woman are equal. However, man and woman are different from each other but created for each other. This complementarity, including sexual difference, draws them together in a mutually loving union that always should be open to the procreation of children (see the Catechism of the Catholic Church, nos. 1602-1605).

These truths about marriage are present in the order of nature and can be perceived by the light of human reason and have been confirmed by divine Revelation in Sacred Scripture.
