You need to put the “selling” of Papal Indulgences in its historical European context though.
During the Dark Ages, if someone committed a crime against another person, the custom was to pay an amount of money to the wronged party or their family as restitution. This was called the “Weregeld” or “man money.” It is the basis of our tort law system in the English speaking world, and that’s why people sue doctors for malpractice, or when they get beat up by cops, or when they get food poisoning at a restaurant. If the money wasn’t paid, a bloodfeud would develop, and one group of kinsmen would fight another group of kinsmen.
The Papacy applied this concept to Indulgences. A sin is a crime against God. So the Papacy asked people to pay for Indulgences to absolve them of all their sin. It sounds terrible to Modern ears, Church + Selling +Money, but that was the normal legal custom and practice in Medieval Europe since the fall of the Roman Empire, or just shorlty thereafter.
Of course, nobody ever points this out. Not in high school texbooks, or college courses, or the History channel, or PBS.
But that’s all you hear about: The Catholic Church sold Indulgences during the Middle Ages, therefore it was corrupt.
As I have shown, selling of the Indulgence was in complete sinc with normal legal practices of the time.
Now there were abuses of the Indulgences. The Indulgence couldn’t be sold to get a deceased person out of Purgatory, but it was. This is what Luther was complaining about.
There was a good Catholic Answers Indulgences program with Dr. Angelino D’Ambrosio a few years back on Catholic Answers. Go to
Catholic.com to the Radio Archive. Every Catholic should listen to it.
