Blessed Souls, I have prayed for thee;
I entreat thee, who are so dear to God,
and who are secure of never losing Him,
to pray for me a miserable sinner,
who is in danger of being damned,
and of losing God forever. Amen.

[for all our departed brothers and sisters]

Merciful Father,
hear our prayer and console us.

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. Amen
