At one time, the Catholic Church sold indulgences. This was meant as a fund raiser allowing a person to pay the church to spend less time in Hell or Purgatory. It was also possible to buy indulgences for people who have were currently spending time in the after life to reduce their sentence and get to Heaven sooner.

The sale of indulgences was one of the reasons Martin Luther rebelled against the Roman Catholic Church. His challenge of them lead to his excommunication.
