> Here's the Vatican's article (in French)

That is not the Vatican’s article at all. It’s just a website. You make it sound like the Catholic Church is openly discussing burning someone, it is not the case. And the trope "faut-il brûler … ?" is common in French and completely metaphorical. Again, nobody is advocating putting anyone on a bonfire.

The Catholic church has a very shall we say complicated stance on democracy, freedom of religion and human rights. Nowadays they realise that the Western world has shifted from their theological and biblical position so they couch it in word salad sophistry.
