O God the Trinity,
your name is wonderful.
You purify the depths of the heart from vices
and make it whiter than the snow.
Give us your compassion.
Renew our hearts by your Holy Spirit
so that we may declare your praise.
Strengthen us by your righteous and royal Spirit
and give us a place in the heavenly Jerusalem;
through our Lord Jesus Christ. Amen.
