Have you ever heard a priest preach against usury?
I ask because this issue seems even more controversial than contraception or abortion, especially because in the minds of some, anti-usury = anti-Jєω.
My Spanish-speaking brother-in-law works for a credit card company customer service, and the stories he tells are so sad! The poor Mexican families have no idea how interest works, and it's obvious they are being deceived/cheated big time.
