That’s Nightcrawler who has long been portrayed as a devout Catholic in the comics. Although the writer who had the longest run on X-men (Christ Claremont) did this with the most flair and was capable of portaying people from a variety of faiths with quite a bit of subtlety given the medium he was working in and how unusual it was in that era to portay a comic book superhero’s faith openly. There are plenty of conversations from the comics I remember where Nightcrawler and Wolverine talk about faith. They are portrayed as been unusually close friends despite their extremely different takes on religion as both respect each other as been men who live by a code of honour. One conversation that stuck in my mind for a long time was Nightcrawler arguing with Wolverine about the morality of using deadly force on a consistent basis. His line that, ‘It may be logical, it may be neccesary, but is right?’ was unusally thoughtful for a comic book of that.
Mentioning superheroes Daredevil also shows a priest in a positive light and of course Daredevil along with Nightcrawler is one of the most prominent Catholic characters in comics.
Rome, Open City is a move that shows a priest in a hugely sympathetic and heroic role. Here’s a clip of the ending below. Warning if you want to watch the whole movie don’t watch the clip:-
