BEADS FOR THE DEAD
This chaplet for the dead consists of four decades (40 beads) in honour
and memory of the forty hours that Our Lord Jesus Christ
passed in Limbo to deliver and conduct to heaven all the
souls of the saints who died before Him.
Begin with the DE PROFUNDIS
On the large beads pray:
Eternal rest grant unto them O Lord, and let perpetual
light shine upon them. May they rest in peace. Amen
O my God I believe in Thee, because Thou art truth itself.
I hope in Thee, because Thou art infinitely merciful.
I love Thee with my whole heart and above all things because
Thou art infinitely perfect, and I love my neighbour as myself
for the love of Thee. I am truly sorry for having sinned,
because Thou art infinitely good and sin displeases Thee.
I firmly resolve, with the help of Thy grace never more to
offend Thee. Amen.
On the small beads pray:
Sweet heart of Mary be my salvation.
Conclude with the DE PROFUNDIS
Indulgence of 60 YEARS each time, applicable to the souls in Purgatory
If you have an old rosary with missing beads you can use it to make this chaplet for the dead.
Leave only the Crucifix and 1 Our Father bead on the pendant and 4 decades of small beads and 3 Our Father beads on the loop.
