November 2nd is All Souls Day - A day to remember in a special way all those who have died, especially those in Purgatory.
The following prayer comes from The Association of Marian Helpers:
Merciful Father, hear our prayer and console us. As we renew our faith in Your Son, whom you raised from the dead, strengthen our hope that all our departed brothers and sisters will share in His resurrection, who lives and reigns with You and the Holy Spirit, one God, for ever and ever.
Eternal rest grant unto them, O Lord, and let perpetual light shine upon them. May they rest in peace. Amen.
