350. Why is the Christian family called a domestic church? (CCC 1655-58, 1666)
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.
