Long before I ever got into Superman in general and L&C in particular, I followed the X-Men for a couple of years in the early 80s. One thing I really liked about the comic was the way it handled religion. The vast majority of comics either don't bring the topic up at all, or else have the people who hold religious beliefs be violent religious extremists or cultists with crazy tenets (e.g., the Superman cults). I really liked the X-Men Kurt Wagner (Nightcrawler) and Kitty Pryde because they were actually superheros with religious convictions. (Kurt was a Christian and Kitty was Jewish.) The comic handled religion wonderfully, in my opinion. I remember one panel in which Kitty was getting ready to head out to Friday night Sabbath services; the nice thing about the scene was that it was presented so matter-of-factly, and it had nothing to do with the greater story-line. They could just as easily have had her getting ready to go see a movie. Instead, they chose to let the reader see that attending a worship service is a regular part of her life. Another scene in another story showed Kurt praying. Wolverine (an atheist) and Nightcrawler had amicable conversations in which they respectfully disagreed with each other's beliefs. I haven't read X-Men in decades, so I don't know how Marvel is currently handling the characters.
In any event, Superman is far and away my favourite superhero. I might enjoy others on occasion, but as Bibbo from the comics would say, "Sooperman's my fav'rit. (sic)"
Joy,
