... I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them who despitefully use you, and persecute you.

And unto him that smiteth thee on the one cheek, offer also the other ...

Dearly beloved, avenge not yourselves but, rather, give place unto wrath; for it is written, Vengeance is mine; I will repay, saith the Lord. Therefore, if thine enemy hunger, feed him; if he thirst, give him drink; for in so doing thou shalt heap coals of fire on his head.

The truly civilized man has no enemies.

I own no enemy on earth. That is my creed.

Wherever you are confronted with an opponent, conquer him with love.

One enemy is too much.

We has met the enemy, and he is us.

If we could read the secret history of our enemies, we should find in each man's life sorrow and suffering enough to disarm all hostility.

We should ever conduct ourselves towards our enemy as if he were one day to be our friend.
