What are Indulgences?
Indulgences are the remission before God of the temporal punishment due to sins whose guilt has already been given. The faithful Christian who is duly disposed gains the indulgence under prescribed conditions for either himself or the departed. Indulgences are granted through the ministry of the Church which, as the dispenser of the grace of redemption, distributes the treasury of the merits of Christ and the Saints.
