Roman Catechism 35.3

Chapter 35 — Part IV: Prayer — The First Petition: Hallowed Be Thy Name

Section 3. Hence, that our prayers may be made with due order, our Saviour has placed this Petition regarding the sovereign Good at the head of all the other Petitions of the Lord's Prayer, thus showing us that before asking the things necessary for ourselves or for others, we ought to ask those that appertain to God's honour, and to manifest and make known to Him the affections and desires of our hearts in this regard. Acting thus, we shall be faithful to the claims and rules of charity, which teaches us to love God more than ourselves and to ask, in the first place, those things we desire on His account, and next, those things we desire on our own.
