Heidelberg Catechism, Lord’s Day 47
["Hallowed be your name" is probably the phrase in the Lord's Prayer that people find the hardest to understand, so Heidelberg gives one Lord's Day over to explaining it simply. It is about honouring, glorifying and praising God, not just in our thoughts ("help us to know you") but also our lives ("what we think, say and do"). To be honest, using the two key sentences ("Help us ...") as prayers, independent of the catechism, would be a worthwhile practice in its own right.]
Q122. What does the first petition mean?
A122. “Hallowed be your name” means:
Help us to truly know you,
to honour, glorify, and praise you
for all your works
and for all that shines forth from them:
your almighty power, wisdom, kindness,
justice, mercy, and truth.
And it means,
Help us to direct all our living—
what we think, say, and do—
so that your name will never be blasphemed because of us
but always honoured and praised.
