Interesting point you raise there, though I should mention, if that's what you're interested in, there is something of an arc going on currently with Nightcrawler of the X-Men that might be more along the lines of what you bring up, insofar as his efforts to create a new set of guiding principles (which is what religion generally is) for the mutant nation of Krakoa without (so many of) the pitfalls of the various permutations of Christianity, Catholicism included, to say nothing of the other Abrahamic faiths.
