We must be on guard against all simplifications and never identify one religion as the source of evil and violence
Cardinal Carlo Maria Martini
It has a remarkable record in bringing together parties at war in developing countries, particularly in Africa, says the BBC's Rome correspondent.
The Archbishop of Milan, Cardinal Carlo Maria Martini, said it was important not to identify members of other religions as evil.
"We must avoid going after scapegoats," said the archbishop, who is seen by many progressives as a possible successor to the Pope.
"Terrorists must be identified and disarmed but that cannot be done if an entire culture, or religion or nation is held responsible.
"We must be on guard against all simplifications and never identify one religion as the source of evil and violence," he said.
Among Muslims taking part in the meeting are the Grand Mufti of Egypt and the President of the World Muslim Council from Saudi Arabia.
We will not accept that a great religion, practised in a great nation, is branded as the religion of violence and terrorism
Yusuf Al-Qaradawi, an Islamic theologian and director of the Sunna Research Centre in Qatar, said that in the wake of the attacks the world had to avoid what he called "a return to the old crusades".
"We will not accept that a great religion, practised in a great nation, is branded as the religion of violence and terrorism because of the actions of a few people," he said.
Mr Al-Qaradawi said that those who carried out the attacks in New York and Washington were the products of a "deformation" of Islam.
