O Lord, you gave your apostles peace,
shed down on us all your holy calm;
gather together with your hand
all those who are scattered,
and bring them like sheep into the fold of your holy Church,
through Jesus Christ our Lord.
Strengthen and confirm me, O Lord, by your cross,
on the rock of faith,
that my mind be not shaken by the attacks of the enemy.
For you alone are holy.
You know, O Lord,
how many and great are my sins,
you know how often I sin,
from day to day,
from hour to hour,
in the things I do
and the things I leave undone.
No more, O Lord,
no more, O Lord my God,
will I provoke you.
No more shall my desire be for anything but you,
for you alone are truly lovable.
And if again I offend in anything,
I humbly ask your mercy
to grant me strength
to live in a manner more pleasing to you.
