What the Pope Said

From the Guardian's transcript, it appears the talk was actually about the relation of reason and science to theology:

It is a moving experience for me to be back again in the university and to be able once again to give a lecture at this podium.

I think back to those years when, after a pleasant period at the Freisinger Hochschule, I began teaching at the University of Bonn.

That was in 1959, in the days of the old university made up of ordinary professors. The various chairs had neither assistants nor secretaries, but in recompense there was much direct contact with students and in particular among the professors themselves.

We would meet before and after lessons in the rooms of the teaching staff. There was a lively exchange with historians, philosophers, philologists and, naturally, between the two theological faculties.

Once a semester there was a dies academicus, when professors from every faculty appeared before the students of the entire university, making possible a genuine experience of universitas - something that you too, Magnificent Rector, just mentioned - the experience, in other words, of the fact that despite our specializations which at times make it difficult to communicate with each other, we made up a whole, working in everything on the basis of a single rationality with its various aspects and sharing responsibility for the right use of reason - this reality became a lived experience.

The university was also very proud of its two theological faculties. It was clear that, by inquiring about the reasonableness of faith, they too carried out a work which is necessarily part of the "whole" of the universitas scientiarum, even if not everyone could share the faith which theologians seek to correlate with reason as a whole.

This profound sense of coherence within the universe of reason was not troubled, even when it was once reported that a colleague had said there was something odd about our university: it had two faculties devoted to something that did not exist: God.
