Q. 100 What doth the preface to the Lord's Prayer teach us? A. The preface to the Lord's Prayer (which is, Our Father, which art in heaven) teacheth us to draw near to God with all holy reverence and confidence, as children to a father, able and ready to help us; and that we should pray with and for others. Why does Jesus tell us to use the plural word Our when we address God? Our Father in heaven instead of My Father in heaven?

WSC Q101: Hallowed Be Your Name

The idea of imparting a body of truth (rudiments of the faith) is found repeatedly in scripture under many different terms and descriptions. We are not given a complete catechism or confession in the Bible. That is because we are to write our own according to the needs of the day. They must refute new heresies as they arise. Our Lord has called us to catechise in His church… to teach disciples the basics of the faith. Make the most of this instruction: memorise your Catechism, listen to the messages, and pray for the Spirit to work.
