Catholics can gain special indulgences for the faithful departed during the first eight days of November.
The latest edition of the Enchiridion of Indulgences tells us how:
1. A plenary indulgence, applicable only to the souls in purgatory, is granted to the faithful who,
1. on any and each day from November 1 to 8, devoutly visit a cemetery and pray, if only mentally, for the departed;
2. on All Souls’ Day (or, according to the judgment of the ordinary, on the Sunday preceding or following it, or on the solemnity of All Saints), devoutly visit a church or an oratory and recite an Our Father and the Creed.
Catholics can also gain a partial indulgence throughout the rest of the year:
2. A partial indulgence, applicable only to the souls in purgatory, is granted to the faithful who
1. devoutly visit a cemetery and at least mentally pray for the dead;
2. devoutly recite lauds or vespers from the Office of the Dead or the prayer Eternal rest
The “Eternal rest” prayer, or “Requiem aeternam” is:
“Eternal rest grant unto them, O Lord, and let perpetual light shine upon them. May they rest in peace.”
The conditions for gaining the indulgence are:
- Do the work while in the state of grace
- Make a sacramental confession within 20 days
- Receive Communion
- Pray for the Pope’s intentions
- Have no attachment to sin, even venial sin (this can involve resolving to love God and reject sin).
