Both Christian and Muslim believe that there is only Holy Bible and one Koran. And unfortunately, the two are different.
The upheld exclusivity in doctrine has excluded the settlement and adjustment in their respective faith.
To me, Bible reveals the realtionship in four dimensions between:
1. man to man; social and professional knowledge issue
2. man to self; life issue
3. man to object; science issue
4. man to God; religion or faith issue
Pope, who represented the Catholic (not the reformed Christians), can touch ethical issue, moral issue, life issue, and science issue, but it is not proper for him to say anything about any other legitimate religion under faith or religion issue at all.
So, my comment is that the Pope made a mistake in this sppech because he "attacked" another religion. This is the core.
