I want to know the answer to the following question:
What event is stated as a reason why the word heretic is used less often in modern times?
All the background I'm provided with is that "The subject of Christian heresy opens up broader questions as to who has a monopoly on spiritual truth, as explored by Jorge Luis Borges in the short story "The Theologians" within the compilation Labyrinths.". Is that enough to answer the question?
