Those killed will be remembered on Friday at 12 noon.
The first bodies of Britons killed in last week's attack landed back on British soil on Wednesday.
A plane carrying eight victims touched down at RAF Brize Norton.
The Churches prayers are as follows:
"Father,
you know our hearts and share our sorrows.
We are hurt by our parting from those whom we loved:
when we are angry at the loss we have sustained,
when we long for words of comfort,
yet find them hard to hear,
turn our grief to truer living,
our affliction to firmer hope
in Jesus Christ our Lord.
Amen."
"Lord, have mercy
on those who mourn
who feel numb and crushed
and are filled with the pain of grief,
whose strength has given up
You know all our sighing and longings:
be near to us and teach us to fix our hope on you
through Jesus Christ our Lord.
Amen."
"Lord, do not abandon us in our desolation.
Keep us safe in the midst of trouble,
and complete your purpose for us
through your steadfast love and faithfulness,
in Jesus Christ our Saviour.
Amen."
"Our eyes, Lord, are wasted with grief;
you know we are weary with groaning.
As we remember our death
in the dark emptiness of the night,
have mercy on us and heal us;
forgive us and take away our fear
through the dying and rising of Jesus your Son.
Amen."
