War is not an inevitable calamity.
Peace is possible.
And because it is possible, peace is our duty: our grave duty, our supreme resposibility.
Certainly peace is difficult; certainly it demands much good will, wisdom, and tenacity.
But man can and he must make the force of reason prevail over the reasons of force. ...
And since peace, entrusted to the resposibility of men and women, remains even then a gift of God, it must also express itself in prayer to Him who holds the destinies of all peoples in His hands.
