We use the Heidelberg Catechism in our worship. Sometimes we read it responsively. Other times I'll work it into my communion liturgy. I'll quote it in my sermons from time to time. I've seen the Catechism used effectively as Sunday school material.

Sometimes Christians live in a terror of universal obligation: AIDS over here, people to be saved over here, a crushing sense of low-level guilt every day of our lives. Question to ask: Where has God put me right now? I need to say no to a whole bunch of other things because if I don't say no I can't say yes to others.

God tells me that I need to provide for my family, discipline and teach my children, and love my wife as Christ loves the church. If I don't do that, I'm being unfaithful and sinful.
