Jack Knight is better known as the superhero "Starman." Jack Knight is the son of Ted Knight, who was the original World War II-era superhero known as "Starman."
At this time, we do not know Jack Knight's religious affiliation or beliefs. His father, Ted Knight, was something of a materialist and probably agnostic, but Jack rebelled against his father in many ways. Furthermore, regardless of the belief's of Jack's father, he may have taken after his mother with regards to religious affiliation and/or belief. Alternatively, his incredible experiences as "Starman" may well have led him down a different path or to different conclusions altogether.
We would welcome additional information from readers more familiar with this character.

A favorite Christmas story of mine would have to be the Starman Christmas story in which the O'Dares all meet for dinner, along with Jack [i.e., Jack Knight or "Starman"], a down-and-out Santa, The Shade and the fortuneteller lady.
