Here's a thought for you: nobody in the Western world really sacrifices anymore. As in, nobody takes possessions/livestock and burns them on an altar, or otherwise disposes of them, as a religious ritual. Likewise, I'm not really aware of people building things (like statues) as offerings to God. Sure, we have plenty of religious artwork, but it seems to me that it's considered as being a form of decoration that's for the Church, not for God Himself.
So, what would it be like if sacrifices were still a common thing in Western/European religion? Doesn't have to be blood sacrifices, taking your dollars/Euros and lighting them on fire is just as good.
