In some missiological circles, if ‘evangelism’ is a ‘boo word’, then ‘interfaith dialogue’ is a ‘hooray word’. Evangelism is so one-way, so high-and-mighty, so two centuries ago. Interfaith dialogue doesn’t assume one ‘faith’ is better or more enlightened than another; nor does it mean that one is telling the other, for it is an attempt at a two-way mutual sharing, and its aim of ‘mutual understanding’ sounds so much better than the ‘conversion’ of another.
I guess Elijah’s encounter on Mount Carmel with the prophets of Baal wouldn’t be a ‘prooftext’ for such dialogues, nor would Jesus’ uncomfortable words, “I am the way, and the truth, and the life. No one comes to the Father except through me.” (John 14:6).
