A plenary indulgence is a grace granted by the Catholic Church through the merits of Jesus Christ, Mary and all the saints to remove the temporal punishment due to sin.
The indulgence applies to sins already forgiven. A plenary indulgence cleanses the soul as if the person had just been baptized.
A plenary indulgence can be obtained during Holy Week for oneself or for a deceased person if one of the following works established by the Church is performed.
1. If during the solemn reservation of the Blessed Sacrament (typically on a side altar), which follows the Mass of the Lord's Supper, you recite or sing the Eucharistic hymn “Tantum Ergo.”
