When Martin Luther wrote the Small Catechism, he wrote it for parents as a tool to teach their children. At the beginning of almost every section, he reminds us by writing: “As the head of the family should teach them in a simple way to his household.”
More than that, this is God’s plan for passing down faith (Deuteronomy 6): “Hear, O Israel: The Lord our God, the Lord is one. You shall love the Lord your God with all your heart and with all your soul and with all your might. And these words that I command you today shall be on your heart. You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise. You shall bind them as a sign on your hand, and they shall be as frontlets between your eyes. You shall write them on the doorposts of your house and on your gates.”
Equipping parents to pass down their faith also something that the Lutheran Church-Missouri Synod has asked churches to focus on.
