To attain a plenary indulgence, three conditions must accompany the prescribed act:
- the faithful must receive the sacrament of confession, either eight days before or after the pious act is performed,
- receive Holy Communion on that day
- and recite prayers for the intentions of the Holy Father (one Our Father and one Hail Mary is the minimum, but any other additional prayers may be added).
One must also remember that one can acquire one plenary indulgence a day.
Indulgenced Acts for the Poor Souls A partial indulgence can be obtained by devoutly visiting a cemetery and praying for the departed, even if the prayer is only mental. One can gain a plenary indulgence visiting a cemetery each day between November 1 and November 8. These indulgences are applicable only to the Souls in Purgatory.
A plenary indulgence, again applicable only the Souls in Purgatory, is also granted when the faithful piously visit a church or a public oratory on November 2. In visiting the church or oratory, it is required, that one Our Father and the Creed be recited.
A partial indulgence, applicable only to the Souls in Purgatory, can be obtained when the Eternal Rest (Requiem aeternam) is prayed. This is a good prayer to recite especially during the month of November:
Requiem aeternam dona ei (eis), Domine, et lux perpetua luceat ei (eis). Requiescat (-ant) in pace Amen.Many families add to the "Prayer Before Meals" the second half of the "Eternal Rest" prayer:Eternal rest grant to them, O Lord, and let perpetual light shine upon them. May the souls of the faithful departed, through the mercy of God, rest in peace. Amen.
Bless us, O Lord, and these thy gifts, Which we are about to receive, from Thy bounty, through Christ, our Lord, Amen. And may the souls of the faithful departed, through the mercy of God, rest in peace. Amen.Other families recite the "Eternal Rest" prayer in between decades of the rosary.
It is a good devotion to pray for the departed all through the year, not just November. After these Souls in Purgatory are in heaven, they will intercede for us. We should all develop prayerful habits, such as praying the "Eternal Rest" prayer when passing cemeteries, to remind us of our eternal destiny.
