Mutually exclusive

Mutual exclusivity represented in a non-overlapping Venn diagram

In monotheistic religion it refers to the notion that for one religion to be true, others cannot be true, since monotheistic religions each have a single god that claims to be the only god.

Universalism rejects this notion by proposing that they are all actually the same god being depicted different ways through allegory.
