Roman Catechism 25.54

Chapter 25 — Part III: The Decalogue — The Second Commandment

Section 54. He should next show that God has appointed no particular punishment. The threat is general; it declares that whoever is guilty of this crime shall not escape unpunished. The various chastisements, therefore, with which we are every day visited, should warn us against this sin. It is easy to conjecture that men are afflicted with heavy calamities because they violate this Commandment; and if these things are called to their attention, it is likely that they will be more careful for the future.
