The mark of Cain is stamped upon our foreheads. Across the centuries, our brother Abel was lain in blood which we drew, and shed tears we caused by forgetting Thy love. Forgive us, Lord, for the curse we falsely attributed to their name as Jews. Forgive us for crucifying Thee a second time in their flesh. For we knew not what we did.
Pope John XXIIIThere is a common belief that under modern conditions peace cannot be assured except on the basis of an equal balance of armaments...[but] true and lasting peace among nations cannot consist in the possession of an equal supply of armaments but only in mutual trust.
Pope John XXIII
