Religious knowledge has become easy to access with as much detail as you might wish. You can learn about Vatican II or the Talmud ad infinitum. But it may mean something different to practitioners when it does not come from another human. An AI can write a sermon; in fact, if some confessional accounts can be believed, a majority of sermons are now at least co-authored with AI. But can it deliver that sermon and move worshippers to go out and do good works? With where things stand now, I doubt it.
