Roman Catechism 37.33

Chapter 37 — Part IV: Prayer — The Third Petition: Thy Will Be Done on Earth as It Is in Heaven

Section 33. Should anyone, adopting the interpretation of St. Cyprian, understand the words in heaven, to mean in the good and the pious, and the words on earth, in the wicked and the impious, we do not disapprove of the interpretation, by the word heaven understanding the spirit, and by the word earth, the flesh, that every person and every creature may in all things obey the will of God.
