Bertone: At "La Sapienza" , the conditions for a dignified and peaceful welcome were lacking
Here is the text of the letter that Vatican secretary of state Cardinal Tarcisio Bertone sent to the rector of the Università La Sapienza, prof. Renato Guarini, together with the address by Benedict XVI.

Esteemed Rector,the Holy Father had gladly accepted your invitation to visit the Università degli Studi "La Sapienza", to offer in this way a sign of affection and of the high regard in which he holds this illustrious institution, which originated centuries ago at the behest of his venerated predecessor.

But since, at the initiative of a decidedly minority group of professors and students, the conditions for a dignified and peaceful welcome were lacking, it has been judged prudent to delay the scheduled visit in order to remove any pretext for demonstrations that would have been unpleasant for all. But in the awareness of the sincere desire on the part of the great majority of the professors and students for culturally significant words from which they can take encouragement for their personal journey in search of the truth, the Holy Father has arranged to send you the text he prepared personally for the occasion. I gladly act as the agent of his decision, attaching the written address with the hope that all may find  within it ideas for enriching reflections and examinations.

I gladly take this opportunity to extend to you, with feelings of profound deference, my cordial regards,

Tarcisio Card. Bertone

Secretary of State
