Let us pray (in silence) [that God’s love strengthen us to do God’s will]
Almighty and merciful God, [or Living God or Eternal God]
it is your gift alone
by which your faithful people
offer you true and laudable service,
grant, we beseech you,
that we may run, without stumbling, towards your promises;
through Jesus Christ
who is alive with you,
in the unity of the Holy Spirit,
one God, now and for ever.
The above ancient prayer is used by Roman Catholics and Episcopalians/Anglicans and others – and on the same day! It has a long, shared history which you can find here with commentary and reflection: Ordinary 31. The above is my rendering in my Book of Prayers in Common.
The collect used on Sunday is for the feast day, All Saints. If you use a collect for the week following (on days when a feast-day collect is not provided), it is not that of the feast, All Saints; it is the one for the week, as above.
