Benedict XVI addressed today the President of Turkey's Office of Religious Affairs. He quoted a medieval pope:

As an illustration of the fraternal respect with which Christians and Muslims can work together, I would like to quote some words addressed by Pope Gregory VII in 1076 to a Muslim prince in North Africa who had acted with great benevolence towards the Christians under his jurisdiction. Pope Gregory spoke of the particular charity that Christians and Muslims owe to one another because we believe in one God, albeit in a different manner, and because we praise him and worship him every day as the Creator and Ruler of the world.

He also spoke of the collaboration Christians and Muslims can undertake:

Above all, we can offer a credible response to the question which emerges clearly from todays society, even if it is often brushed aside, the question about the meaning and purpose of life, for each individual and for humanity as a whole. We are called to work together, so as to help society to open itself to the transcendent, giving Almighty God his rightful place. The best way forward is via authentic dialogue between Christians and Muslims, based on truth and inspired by a sincere wish to know one another better, respecting differences and recognizing what we have in common. This will lead to an authentic respect for the responsible choices that each person makes, especially those pertaining to fundamental values and to personal religious convictions.

Same Pope. Same speech-writer?
