Lumen Gentium
Dogmatic Constitution On The Church
11.
The family is, so to speak, the domestic church. In it parents should, by their word and example, be the first preachers of the faith to their children; they should encourage them in the vocation which is proper to each of them, fostering with special care a vocation to a sacred state.
35.
In connection with the prophetic function is that state of life which is sanctified by a special sacrament obviously of great importance, namely, married and family life. For where Christianity pervades the entire mode of family life, and gradually transforms it, one will find there both the practice and an excellent school of the lay apostolate. In such a home husbands and wives find their proper vocation in being witnesses of the faith and love of Christ to one another and to their children. The Christian family loudly proclaims both the present virtues of the Kingdom of God and the hope of a blessed life to come. Thus by its example and its witness it accuses the world of sin and enlightens those who seek the truth.
