Being disguised under the disfigurement of an ugly crucifixion and death, the Christ upon the cross is paradoxically the clearest revelation of who God is.

Whoever removes the Cross and its interpretation by the New Testament from the center, in order to replace it, for example, with the social commitment of Jesus to the oppressed as a new center, no longer stands in continuity with the apostolic faith.

Without Easter, Good Friday would have no meaning. Without Easter, there would be no hope that suffering and abandonment might be tolerable. But with Easter, a way out becomes visible for human sorrows, an absolute future: more than a hope, a divine expectation.

We are not only interested in those aspects of the mystery of the Roman Catholic Church which set her apart from the other Christian communities, but also to show how often they are central beliefs by describing what is specifically Catholic in such a way that the partner in dialogue can see, even from his own standpoint, the inner consistency.

Thus it is necessary to commence from an inescapable duality: the finite is not the infinite.

The greatest tragedy in the history of Christianity was neither the Crusades nor the Reformation nor the Inquisition, but rather the split that opened up between theology and spirituality at the end of the Middle Ages.

St. Paul would say to the philosophers that God created man so that he would seek the Divine, try to attain the Divine. That is why all pre-Christian philosophy is theological at its summit.
