Roman Catechism 37.34

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

Section 34. This Petition Contains an Act of Thanksgiving — This Petition also includes thanksgiving. We revere the most holy will of God, and in transports of joy celebrate all His works with the highest praise and acknowledgment, being assured that He has done all things well. It is certain that God is omnipotent; and the consequence necessarily forces itself on the mind that all things were created at His command. We also confess the truth that He is the supreme Good. We must, therefore, confess that all His works are good, for to all He imparted His own goodness. But if we cannot fathom in everything the divine plan, let us in all things banish every doubt and hesitation from the mind, and with the Apostle declare that his ways are unsearchable.
