When I taught or co-taught global studies, it was a topic that the curricula, unlike the often superficial passes through other important historical processes, focused on at relatively inordinate length, so this Cultural Literacy on the concept of an indulgence, at three sentences and three questions on a half-page document, was insufficient.
Still, it opens the door to discuss this weird medieval financial instrument–swapping earthly gains (often obtained through exploitative and violent means) for heavenly salvation. As the reading observes, indulgences were one of the things that infuriated Martin Luther and therefore began The Reformation. They also demonstrate, should anyone care to take a discussion in this direction, the apparently bottomless human capacity for self-delusion, corruption, and folly.
