Spare Us, Good Lord.

O God the Father, Creator of heaven and earth,
Have mercy upon me.
O God the Son, Redeemer of the world,
Have mercy upon me.
O God the Holy Spirit, Sanctifier of the Faithful,
Have mercy upon me.
O holy, blessed, and glorious Trinity, one God, 
Have mercy upon me.
Remember not, Lord Christ, my offenses nor the offenses of my forefathers; neither reward me according to my sins. Spare me, good Lord, spare your people, whom you have redeemed with your most precious blood, and by your mercy preserve us, for ever.,
Spare us, good Lord.
