Pope John Paul said on Saturday he hoped that the human tragedy of the war in Iraq would not set Christians and Muslims against each other and spark "a religious catastrophe." "War must never be allowed to divide world religions," he told visiting Roman Catholic bishops from Indonesia, the world's largest Muslim country. The Pope said good inter-religious relations were important "at this moment of heightened tension in the entire world community." "Let us not permit a human tragedy to become a religious catastrophe," he said.
