Scribe, I can think off the top of my head that Graham, Aaron and Dan have each used overt religious imagery and events that are grounded in our world (the last church, the cathar heresy, etc), but heck, the use of angels (angels that come straight out of western Christian visual traditions rather than other visual traditions), Catholic imagery (the ecclesiarchy, the redemptionists, etc), medieval crusader imagery (eg dark angels, black templars), priesthoods, Faustian bargains, devils and daemons, the use of common religious ideas of sin and major "sins", patriarchal (white) images of monotheistic divinity, and so on, means that real-world religion is threaded through the setting deeply and decidedly so. It is not just names, but also adaptations of realworld events - what is Nikea but obviously Nicea? The reformation, the great schism, the arian debate, the emergence of realworld religions - all are there in the setting. There are 1000s of these allusions to (predominantly) western religion in the literature and lore of 40k - in part because it's makers are themselves part of western (especially british-european) culture.
Dan is very intrigued by names, by history, by religion and often by the legacy of literature - and indeed as with many writers, Shakespeare. I think of Prospero Burns - a title people feel was wrong for the book itself but that was because people wanted a simple battle narrative (perhaps more akin to Necropolis?) - but Prospero isn't just a planet in the 40k setting, he is of course the wizard in The Tempest, after which the planet was named by the writers of 40k. The themes of the Tempest run through that book - the loss of knowledge and magic, the danger of nature, of exile and expulsion and status and parentage, etc.
And that's not just Dan; when the 40k writers - science fiction writers - are on top-form they are doing what often sci-fi and fantasy writers do; i.e. use it as a tool to explore a thematic question or set of questions. And so exploring the power of names, of religion, of devotion - ideas steeped through the IP itself - seems pretty normal.

Cinema itself is a trick of time — still pictures passed through a focused beam of light at 24 frames per second. We are reminded of that in La Jetée...
