It is an honest and straightforward assessment, well worth reading. He concludes thus:

Every great nation and religion has shadows and indeed crimes in their histories. This is certainly true of Catholicism and all Christian denominations. We should not airbrush these out of history, but confront them and then explain our present attitude to them.

These are also legitimate requests for our Islamic partners in dialogue. Do they believe that the peaceful suras of the Koran are abrogated by the verses of the sword? Is the programme of military expansion (100 years after Muhammad’s death Muslim armies reached Spain and India) to be resumed when possible?

Do they believe that democratic majorities of Muslims in Europe would impose Sharia law? Can we discuss Islamic history and even the hermeneutical problems around the origins of the Koran without threats of violence?

Obviously some of these questions about the future cannot be answered, but the issues should be discussed. Useful dialogue means that participants grapple with the truth and in this issue of Islam and the West the stakes are too high for fundamental misunderstandings.

Both Muslims and Christians are helped by accurately identifying what are core and enduring doctrines, by identifying what issues can be discussed together usefully, by identifying those who are genuine friends, seekers after truth and cooperation and separating them from those who only appear to be friends.
