But we thought we should also call your attention to the fact that the Man of Steel is also a Catholic. For instance, the arch-villain of the franchise is a guy name Lex Luthor. Obviously, "Luthor" is a play on "Luther." Moreover, Superman's big "S" stands for "Sacraments." He channels the power of God through his physical self. Plus, he believes lying is never justified, so he must be a Thomist.
Even though you've been raised as a human being, you're not one of them. They can be a great people, Kal-El. They wish to be. They only lack the light to show the way. For this reason above all - their capacity for good - I have sent you to them...my only son.
