The Heidelberg Catechism: Lord's Day 47
122. Question: What is the first petition?
Answer: Hallowed be Thy Name. That is: Grant us first of all that we may rightly know Thee, and sanctify, glorify, and praise Thee in all Thy works, in which shine forth Thy almighty power, wisdom, goodness, righteousness, mercy, and truth. Grant us also that we may so direct our whole life– our thoughts, words, and actions– that Thy Name is not blasphemed because of us but always honored and praised.
