349. What is the attitude of the Church toward those people who are divorced and then remarried? The Church, since she is faithful to her Lord, cannot recognize the union of people who are civilly divorced and remarried. "Whoever divorces his wife and marries another, commits adultery against her; and if she divorces her husband and marries another, she commits adultery" (
Mark 10:11-12). The Church manifests an attentive solicitude toward such people and encourages them to a life of faith, prayer, works of charity and the Christian education of their children. However, they cannot receive sacramental absolution, take Holy Communion, or exercise certain ecclesial responsibilities as long as their situation, which objectively contravenes God's law, persists.

The Christian family is called the domestic church because the family manifests and lives out the communal and familial nature of the Church as the family of God. Each family member, in accord with their own role, exercises the baptismal priesthood and contributes toward making the family a community of grace and of prayer, a school of human and Christian virtue and the place where the faith is first proclaimed to children.
