Yesterday, Pope Francis spoke on marriage and complementarity at the Vatican’s colloquium on the subject. He said:

I would like to begin by sharing with you a reflection on the title of your colloquium. “Complementarity”: it is a precious word, with multiple meanings. It can refers to situations where one of two things adds to, completes, or fulfills a lack in the other. But complementarity is much more than that. Christians find its deepest meaning in the first Letter to the Corinthians where Saint Paul tells us that the Spirit has endowed each of us with different gifts so that-just as the human body’s members work together for the good of the whole-everyone’s gifts can work together for the benefit of each (cf. 1 Cor. 12). To reflect upon “complementarity” is nothing less than to ponder the dynamic harmonies at the heart of all Creation. This is the key word, harmony. All complementarities were made by our Creator, because the Holy Spirit, who is the Author of harmony, achieves this harmony.

It is fitting that you have gathered here in this international colloquium to explore the complementarity of man and woman. This complementarity is at the root of marriage and family, which is the first school where we learn to appreciate our own and others’ gifts, and where we begin to acquire the arts of living together. For most of us, the family provides the principal place where we can begin to “breathe” values and ideals, as well to realize our full capacity for virtue and charity. At the same time, as we know, families are places of tensions: between egoism and altruism, reason and passion, immediate desires and long-range goals. But families also provide frameworks for resolving such tensions. This is important. When we speak of complementarity between man and woman in this context, let us not confuse that term with the simplistic idea that all the roles and relations of the two sexes are fixed in a single, static pattern. Complementarity will take many forms as each man and woman brings his or her distinctive contributions to their marriage and to the formation of their children — his or her personal richness, personal charisma. Complementarity becomes a great wealth. It is not just a good thing but it is also beautiful.
