A Christian family should be a miniature church. All Christian family members are invited to strengthen one another in faith and to outdo one another in their zeal for God. They should pray for and with eachother and collaborate in works of charity. (2226-2227)
Love one another with brotherly affection; outdo one another in showing honor. Never flag in zeal, be aglow with the Spirit, serve the Lord. Rom 12:10
Parents stand in for their children with their own faith, have them baptized, and serve as their models of faith. That means that parents should make it possible for their children to experience how valuable and beneficial it is to live in the familiar presence of the loving God. At some time however, the parents, too will learn from their children's faith and hear how God speaks through them, because the faith of young people is often accompanied by greater devotion and generosity and "because the Lord often reveals to a younger person what is better" (St. Benedict of Nursia, Rule, chap. 3,3)
