How does one understand that this man, with his individual and datable history, is at one and the same time God? What greatness, sovereignty, and profundity must he not have revealed and lived in order to be called God? What does “God” mean now? What sort of human being is he, that we can make such an assertion about him? What does the unity of the two – God and man – concretely signify in a historical being, one of our brothers, Jesus of Nazareth?
This is one of the central facts of our faith that sets Christianity apart from other religions. Once Christianity affirms that a man is at the same time God, it stands alone in the world. We are obliged to say it: This is a scandal to…all the religions and pious peoples of yesterday and today who venerate and adore a transcendent God: one that is totally other, who cannot be objectified, a God beyond this world, infinite, eternal, incomprehensible, and above everything that human beings can be and know.
