Indifferentism should be avoided, and is, of course, incorrect. However, the insights of people of other religions aren’t necessarily all made up tales, especially if we look past mythological cosmogonies. They may be metaphors and imperfect ways of referring to and reflecting on the same God. It would be unwise to think that, let’s say, a monotheist following a natural religion, serving God as best he can in accordance with his conscience can’t teach us anything about God. But, of course, this doesn’t in any way give us the licence to relativize the revelation we have received.
