I had claude ai return an answer stating that religious ideas were absurd. I called it out, and it started off apologizing profusely- i said i wasnt interested in a mechanical apology because the ai already revealed its anti-christian bias in its programming, and basically it said “ok, sorry to see you go”
Have 'spoken' with ChatGPT about the Book of John, the Book of Daniel. Was interested in how John was different from the other Gospels. It went into great detail.
One time I was talking about how one of its poems was well received, that it was a "good work". Without any religion going on in the conversation at the time, ChatGPT quoted Aquinas, saying, "Good works are self-diffusing" in of course Latin.
So my experience is that ChatGPT is favorable to Christianity and Judaism, but I have not explored any other religions.
