M. Leary has an interesting article (probably more interesting if you have already seen the movie, which I have not) on the few references to gods and deity in Marvel’s The Avengers.
Not one to sit on his duff when justice can be served, Captain America begins preparing to do his thing. “Wait,” Black Widow says. “You might wanna sit this one out, Cap. These guys are basically gods.” To which, the Captain replies, “There’s only one God, ma’am. And I don’t think he dresses like that.” And out of the plane Captain leaps, his fall to earth surely cushioned by his ideological purity.
Leary makes the valid point that whenever you pull God into the conversation, you can’t just side-step him. Somehow, a simple reference draws in a world of meaning.
