I don't think there's a mandate to be found in sacred Scripture that is more solemn than this one. That we are to teach our children the truth of God's Word is a sacred, holy responsibility that God gives to His people. And it's not something that is to be done only one day a week in Sunday school. We can't abdicate the responsibility to the church. The primary responsibility for the education of children according to Scripture is the family, the parents. And what is commanded is the passing on of tradition.
