What a cruel thing is war: to separate and destroy families and friends, and mar the purest joys and happiness God has granted us in this world; to fill our hearts with hatred instead of love for our neighbors, and to devastate the fair face of this beautiful world.

Never think that war, no matter how necessary, nor how justified, is not a crime.

War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn to live together in peace by killing each other's children.

War is mankind's most tragic and stupid folly; to seek or advise its deliberate provocation is a black crime against all men.

Nothing doth worse become a man (I will not say a Christian man) than war.

What a terrible thing war is, what a terrible thing!

I think war is a dangerous place.

Unless a nation's life faces peril, war is murder.

There is nothing in the world more harmful than war and more foolish than armament

War should be made a crime, and those who instigate it should be punished as criminals.

Further, nothing, except sin, is contrary to an act of virtue. But war is contrary to peace. Therefore war is always a sin.

I appeal for cessation of hostilities, not because you are too exhausted to fight, but because war is bad in essence. You want to kill Nazism. You will never kill it by its indifferent adoption.

who does not know the evils of war cannot appreciate its benefits

I have never advocated war except as means of peace, so seek peace, but prepare for war. Because war... War never changes. War is like winter and winter is coming. Coming like a mysterious adventurer. I used to be an adventurer until I took an arrow to the knee. A knee that will not bend, like Leonidas at Thermopylae.
