"Henceforth the idea of human unity is born. That image of God, the image of the Word, which the incarnate Word restores and gives back to its glory, is "I myself"; it is also the other, every other. It is that aspect of me in which I coincide with every other man, it is the hallmark of our common origin and the summons to our common destiny. It is our very unity in God.If, then, there took place in our past some "decisive" event that […] opened out to us the perspective of "the joy of an essentially universal union", we shall know where such an event took place.[…] Anyway, it is a fact that nowhere outside the influence of Christianity has man ever succeeded in defining its conditions; he has always wavered between the imagining of an individual survival in which beings remain separated and a theory that absorbs them in the One."
