Fr. Z has a great prayer against persecutors and evil-doers, like those imposing the HHS mandate on Catholics and other people of faith.
Hostium nostrorum, quaesumus, Domine, elide superbiam: et eorum contumaciam dexterae tuae virtute prosterne. Per Dominum.
Crush, O Lord, we beseech Thee, the pride of our enemies: and prostrate their arrogance by the might of Thy right hand. Through our Lord.
