Roman Catechism 30.24

Chapter 30 — Part III: The Decalogue — The Seventh Commandment

Section 24. Those who defraud their creditors, who deny their just debts, and also those who purchase goods on their own, or on another's credit, with a promise to pay for them at a certain time, and do not keep their word, are guilty of the same crime of robbery. And it is an aggravation of their guilt that, in consequence of their want of punctuality and their fraud, prices are raised to the great injury of the public. To such persons seem to apply the words of David: The sinner shall borrow, and not pay again.
