Prayer of St. Isaac

I beg and beseech you, Lord:
grant to all who have gone astray a true knowledge of you,
so that each and every one may come to know your glory.
In the case of those who have passed from this word
lacking a virtuous life and having had no faith,
be an advocate for them, Lord,
for the sake of the body which you took from them,
so that from the single united body of the world
we may offer up praise to Father, Son, and Holy Spirit
in the kingdom of heaven, an unending source of eternal delight.
