They're referring to this
I asked Bendis how much his Jewish background factors into his particular approach and vision for Superman. Specifically, Superman was original conceived as representing a great deal of Jewish social ideals and opinion, not to mention quite obvious storytelling influence from the story of Moses and the use of the name “El” (and the associated implications of the Hebrew lāmed to “L”). Later, however, stories focused on Christian symbolism and treated Superman as comparable to Jesus. I always favored the original approach, and wondered if Bendis would return the character to those traditional roots once more.
Bendis replied, "I can honestly tell you the choices we've made and bring to Superman are deeply connected to his origins. I don't want to say too much right now, but it's a reflection of where he came from and the world we live in now."
So really, Bendis didn't mention anything of the sort, the interviewer brought it up.
Yes, but he seemed to be really into focusing n this aspect of Superman, and he also mentioned that he wanted to get back to Clark the reporter, and develope /flesh out his entire cast of characters...
