the spirits of those who die in the Lord live with you,
and the souls of the faithful,
after they are delivered from the burden of the flesh,
are in joy and bliss in your presence.
We give you humble thanks
that it has pleased you to deliver this our brother
out of the miseries of this sinful world.
We pray, in your goodness
fill up the number of your chosen ones and hasten your kingdom,
that with all those who have departed in the true faith of your holy name
we also may have our perfect fulfillment and bliss,
both in body and soul,
in your eternal glory;
through Jesus Christ our Lord. Amen.
