Purity Prayer – St Gregory The Great

Almighty God,
To whom all hearts are open,
All desires known,
And from whom no secrets are hidden,
Cleanse our hearts,
By the breath of your Holy Spirit,
That we may fully love you,
And praise well your holy name.
Through Jesus Christ our Lord.

– Gregory The Great / Pope Gregory The First (~540-604)
