St. Ambrose teaches that perfect virtue leaves no desire for vengeance and that true charity leaves no room for anger. The Samaritans refused to receive Jesus because they bore vengeance and anger in their heart. 

What obstacles keep me separated from God? Do I bear anyone vengeance? Am I angry at anyone?  

O gracious God, may I be set free from anger and vengeance. May I be liberated to love God as fully as I am loved by God.
