while I see similarities I think your examples are pushed to the limit. We don't really know anything about the Speaker. He could be moses, he could be satan, he could be lucifer. The Traveler is either god, or is a god. Destiny has a lot of lore based in religion just not all Christianity. (this is a destiny related topic that deserves to be on the main page with religion in it. see the other thread to understand why this was an issue)
