Why did the common man get mad at the selling of indulgences?

Luther became increasingly angry about the clergy selling 'indulgences' - promised remission from punishments for sin, either for someone still living or for one who had died and was believed to be in purgatory. Luther had come to believe that Christians are saved through faith and not through their own efforts.

hope it helps.

have a great day.
