Roman Catechism 37.7

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

Section 7. Another very apt comparison to denote the miserable condition of mankind is that wherein we are likened to children who, if left to go their own way, are thoughtlessly attracted by everything that presents itself. Truly we are children, thoughtless children, wholly devoted to vain conversations and frivolous actions, once we become destitute of divine assistance; and hence the reproof which divine wisdom directs against us: O children, how long will you love childishness, and fools covet those things which are hurtful to themselves? while the Apostle thus exhorts us: Do not become children in sense.
