Corruption in the Church
During the Middle Ages
Originally, pardons (or indulgences) were supposed to be given by priests to followers who wanted to be forgiven for their sins. But Pardoners became greedy and sold them to anyone who wanted one.
Some church members would charge money to visit holy relics. Others would falsely claim that random objects were in fact holy ones. Additionally, they would sell Church positions to the highest bidder as a way to make money, regardless of that person's religious practices.
