43 - You have heard that it hath been said, Thou shalt love thy neighbor, and hate thy enemy.
44 - But I say to you, Love your enemies: do good to them that hate you: and
pray for them that persecute and calumniate you: 45 - That you may be the children of your Father who is in heaven, who maketh his sun to rise upon the good, and bad, and raineth upon the just and the unjust.
46 - For if you love them that love you, what reward shall you have? do not even the publicans this?
47 - And if you salute your brethren only, what do you more? do not also the heathens this?
- Matthew, 5
Now, if I'm silly, imagine the fellow who wrote this:
Prayer for One's Enemies
Here's a little something from a person who gave all he had for the sake of his Catholic Faith: including his life, after a year and a half in prison!
Almighty God, have mercy on (Name(s)) and on all that bear me evil will and would me harm, and on their faults and mine together, by such easy, tender, merciful means, as thine infinite wisdom best can devise; vouchsafe to amend and redress and make us saved souls in heaven together, where we may ever live and love together with thee and thy blessed saints, O glorious Trinity, for the bitter passion of our sweet Savior Christ. Amen!
St. Thomas More, (1477-1535)
