“Until there is peace between religions, there can be no peace in the world.”

Address at the opening of the Exhibit on the World's Religions at Santa Clara University (31 March 2005) note: Elaborations and extensions of this declaration occur in Küng's later writings, including: There will be no peace among the nations without peace among the religions. There will be no peace among the religions without dialogue among the religions. There will be no dialogue among the religions without global ethical standards. There will therefore be no survival of this globe without a global ethic.

Context: "Religion" is a nearly useless term. It's a term like "sports". Now there are sports like Badminton and sports like Thai Boxing, and they have almost nothing in common apart from breathing. There are sports that are just synonymous with the risk of physical injury or even death … There is, I'm happy to say, a religion of peace in this world, but it's not Islam. The claim that Islam is a religion of peace that we hear ceaselessly reiterated is completely delusional. Now Jainism actually is a religion of peace. The core principle of Jainism is non-violence. Gandhi got his non-violence from the Jains. The crazier you get as a Jain, the less we have to worry about you. Jain extremists are paralysed by their pacifism. Jain extremists can't take their eyes off the ground when they walk lest they step on an ant... Needless to say they are vegetarian. So the problem is not religious extremism, because extremism is not a problem if your core beliefs are truly non-violent. The problem isn't fundamentalism. We often hear this said: these are euphemisms... The only problem with Islamic fundamentalism are the fundamentals of Islam.
