When Civilizations Meet: How Joseph Ratzinger Sees Islam
Yes to reciprocity, no to “do-goodism”
The pope’s position never falls into the justification of terrorism and violence. Sometimes, even when it comes to Church figures, people slip into a generic kind of relativism: after all, there’s violence in all religions, even among Christians; or, violence is justified as a reply to other violence… No, this Pope has never made allusions of this kind.
But, on the other hand, he has never fallen into the behaviour found in certain Christian circles in the West marked by “do-goodism” and by guilt complexes. Recently, some Muslims have asked that the Pope ask forgiveness for the Crusades, colonialism, missionaries, cartoons, etc. He is not falling in this trap, because he knows that his words could be used not for building dialogue, but for destroying it. This is the experience that we have of the Muslim world: all such gestures, which are very generous and profoundly spiritual, to ask for forgiveness for historical events of the past, are exploited and are presented by Muslims as a settling of accounts: here, they say, you recognize it even yourself: you’re guilty. Such gestures never spark any kind of reciprocity.
