Roman Catechism 39.12

Chapter 39 — Part IV: Prayer — The Fifth Petition: Forgive Us Our Trespasses as We Forgive Those Who Trespass Against Us

Section 12. The Consequences Of Sin — And for what? Only for this, that separating ourselves from God our Father, who is the supreme Good, and lured by the most base rewards of sin, we may devote ourselves to the devil, to become his most wretched slaves. Language is inadequate to depict the cruel tyranny which the devil exercises over those who, having shaken off the sweet yoke of God, and broken the most lovely bond of charity by which our spirit is bound to God our Father, have gone over to their relentless enemy, who is therefore called in Scripture, the prince and ruler of the world, the prince of darkness, and king over all the children of pride. Truly to those who are oppressed by the tyranny of the devil apply these words of Isaias: O Lord our God, other lords besides thee have had dominion over us.
