Captain America ("there's only one god"), Dom from "Fast and the Furious" (wears a cross), Julius (John Wick, very concerned about John going after the Pope), anyone whose funeral or wedding is held at a church ...
Daredevil in the Netflix series is more blatant, but you did say movies.
Not exactly a huge saturation of monotheists, is it? One character that I recognize and two I've never heard of, only one of which meets the criteria.
Sounds like some diversity is needed...
