Faith dialogue is impossible with Islam. I would love to see Pope Benedict point out that Christ taught us to call God our Father. In Islam, this is blasphemy. Allah is a slave master to whom you are to submit.
Want to end a faith dialogue real quick? Just begin saying the "Our Father" and it will be over. We have no common faith ground and we are not worshipping the same God.
There is an old expression: "actions speak louder than words". During the recent war in Lebanon, the Maronite Catholics opened their homes and communities to Muslims fleeing from the south. They followed our Lord's words to "feed, clothe and shelter the poor". In the evening, they invited their Muslim 'brothers' to join them in prayer. The children responded with many questions about Jesus Christ. One even asked a priest to give him a cross to wear. The priest agreed but only with the parent's permission, which was willingly granted.
Following the cease fire, the Muslims packed up their belongings and returned to their devastated villages in the south. They invited the priest to come visit them and so he did, on 3 separate occasions. These Muslims readily admitted that if a christian had fled to their village, they would not have done anything. Their hearts were and opened by the charity given them by Catholics, both lay and religious. On his 3rd visit to one family, they insisted that he join them for dinner and asked him to bless their home.
God works in remarkable ways. Please remember and pray for all of these Muslims who have begun to understand the teachings of Jesus Christ.
