The Objection: The other religions.
Christians seem to greatly over-play the differences between their faith and all the other ones. Though millions of people in other religions say they have encountered God, have built marvelous civilizations and cultures, and have had their lives and characters changed by their experience of faith, Christians insist that only they go to heaven – that their religion is the only one that is ‘right’ and true. The exclusivity of this is breath taking. It also appears to many to be a threat to international peace.

Response: Inclusivism is really covert exclusivism. It is common to hear people say: ‘No one should insist their view of God is better than all the rest. Every religion is equally valid.’ But what you just said could only be true if: First, there is no God at all, or second, God is an impersonal force that doesn’t care what your doctrinal beliefs about him are. So as you speak you are assuming (by faith!) a very particular view of God and you are pushing it as better than the rest! That is at best inconsistent and at worst hypocritical, since you are doing the very thing you are forbidding. To say ‘all religions are equally valid’ is itself a very white, Western view based in the European enlightenment’s idea of knowledge and values. Why should that view be privileged over anyone else’s?
