I don't know if you in the US will be able to follow this link but it's a really interesting series of 15 min talks by Neil MacGregor, ex curator of the British Museum, now working in some top museum in Germany. Excellent credentials. Here's an excerpt from Wikipedia, from which longer article I learn, to my surprise, that he is a devout Christian.
He has run several most interesting series on examining the backgrounds to many artefacts and currently he is looking at Living with the Gods. It's of general interest, not even remotely considering the Bible, but is considering the routines of religions (that's plural), what they might have meant then and now, and similarities and differences. He bases his talk around some artefact that may or may not have (to us) religious significance. The artefact might be a garment, a coin, a shard...
I mention this because it might give some insight into how some different religious practices came into existence. How those practices play out in other cultures, religions, time periods. One recently was about sacrifice, starting with Incas, moving through various stages, taking in Christianity, and moving forward.
