The relationship between Christianity and Islam throughout history has been often characterized by misunderstanding, rivalry, and frequently hostility. As illustrated in the recent movie, The Kingdom of Heaven, these tensions reached their pinnacle of ugliness in Crusades. In today’s post 9-11 world, these same misunderstandings, rivalries, and hostilities are in danger of being ignited again as extremists on both sides attempt to persuade us that Christianity and Islam are fundamentally opposed to one another. Such claims can only be overcome by persistent efforts at dialogue that promotes understanding and reconciliation. Only such sincere and honest exchange can bring about the understanding that will enable Christians and Muslims, together with Jews, to coexist peacefully in the 21^st century.
