Moral Case: I’m jealous of my best friend’s new car to the point that I am “coveting my neighbor’s goods”. What’s so bad about that?
Catholic Moral Teaching:
- You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, or his manservant, or his maidservant, or his ox, or his ass, or anything that is your neighbor’s. Every one who looks at a woman lustfully has already committed adultery with her in his heart.
2514 St. John distinguishes three kinds of covetousness or concupiscence: lust of the flesh, lust of the eyes, and pride of life. In the Catholic catechetical tradition, the ninth commandment forbids carnal concupiscence; the tenth forbids coveting another’s goods.
The sensitive appetite leads us to desire pleasant things we do not have, e.g., the desire to eat when we are hungry or to warm ourselves when we are cold. These desires are good in themselves; but often they exceed the limits of reason and drive us to covet unjustly what is not ours and belongs to another or is owed to him.
