" The illusion of being superior engenders the need to prove it; and so oppression is born. A bishop in Africa told me that, even though there were few Christians in the area, he had built his cathedral bigger than the local mosque. All this to prove that Christianity was a better, more powerful religion than Islam. So we build walls around our group and cultivate our certitudes. Prejudice grows on such walls. How did we, the human race, get to this position where we judge it natural not just to band ourselves into groups, but to set ourselves group against group, neighbour against neighbour, in order to establish some ephemeral sense of superiority? One of the fundamental issues for people to examine is how to break down these walls that separate us one from another; how to open up one to another; how to create trust and places of dialogue. "
