The Anscombe Society believes that the intact, stable family is the most fundamental unit of society. We hold that the intact family consists of a man and woman, bound together by marriage, along with whatever children they may have. We define marriage as the exclusive and monogamous union between a man and a woman oriented towards procreation and the rearing of children and grounded in a life-long commitment to mutual love and aid. In most societies, this commitment is recognized by the state and by social custom.

We believe that the family provides the social support necessary for a stable society. The intact, healthy family offers the best environment for raising children, providing them with the love, support, and education necessary for success in adult life. The family, therefore, is the best institution for nurturing and rearing future generations, preparing them for the responsibilities that they will need to lead society later on.

The Anscombe Society believes that the institution of marriage is integral to the existence of the family. We believe that marriage is a social as well as personal good, contributing to the health and happiness of both spouses and their children. Scientific evidence from a variety of fields as well as human experience have shown that deviations from the marital norm are generally harmful, especially when these deviations challenge the institution of marriage itself, as in the cases of same-sex unions and casual divorce.
