For many Catholics, “dialogue” is a dirty word.
In their minds, it’s code for the kinds of ecumenism and interfaith relations that emphasize similarities and dismiss differences.
“Dialogue” means “we’re all climbing the same mountain, which is God — but we’re on different paths” or “dogma divides, and we are trying to move past dogma to find our common ground.”
In other words, “dialogue” means indifferentism — the idea that all religions are essentially the same. “Dialogue” means universalism — if all religions are the same, then everyone will be saved in the end. “Dialogue” means, therefore, that no one needs to be converted to the Catholic faith because they’re okay where they are.
