 Sure. And indulgence, and it's a funny sounding word to modern years because it almost sounds as though like it's permission to do something bad. And of course, that's not what it means. So an indulgence is the churches acting under the authority given by Christ to bind and loose. Whatever you bind on earth is bound in heaven. Whatever you loose on earth is loose in heaven. So we can be loosed from the need to do penance for our sins that have been forgiven.
