A Prayer for Unity

O Sovereign and Almighty Lord,
look down from heaven on your Church,
on all your people,
and on all your flock.
Save us all,
your unworthy servants,
the sheep of your fold.
Give us your peace,
your help,
and your love,
and send to us the gift of your Holy Spirit,
that with a pure heart and a good conscience
we may salute one another with an holy kiss,
without hypocrisy,
and with no hostile purpose,
but guileless and pure in one spirit,
in the bond of peace and love,
one body and one spirit,
in one faith,
even as we have been called in one hope of our calling,
that we may all meet in the divine and boundless love,
in Christ Jesus our Lord,
with whom you are blessed.

A Prayer for Defense and Deliverance

We ask you, Master,
be our helper and defender.
Rescue those of our number in distress;
raise up the fallen;
assist the needy;
heal the sick;
turn back those of your people who stray;
feed the hungry;
release our captives;
revive the weak;
encourage those who lose heart.
Let all the nations realize that you are the only God,
that Jesus Christ is your Son,
and that we are your people and the sheep of your pasture.
