Catechism number 2541

The economy of law and grace turns men's hearts away from avarice and envy. It initiates them into desire for the Sovereign Good; it instructs them in the desires of the Holy Spirit who satisfies man's heart.
The God of the promises always warned man against seduction by what from the beginning has seemed "good for food . . . a delight to the eyes . . . to be desired to make one wise."³²⁹
