So I recently listened to an episode of the Data over Dogma podcast specifically regarding angels and demons. It’s hosted by Dan Beecher (an atheist podcaster) and Dr. Dan McClellan (a Bible scholar), and they discuss how angels and demons are actually depicted/described in the Bible, compared to the extra-biblical descriptions of both that we’ve gotten over the millennia. It’s about an hour but should serve as a nice little primer on the subject, with some recommendations for further study.
Check out the “Leviathan” album by Mastodon. A good number of bangers on there, one after another
