Yeah, Emcee, I haven't watched the whole John/Stephanie interview yet, but they sing a song together at the end - a rather quaint sounding one.
The context of that line from "I'm With You" is:
Oh, you are the sunshine,
You are the face that I dream of,
You are your mother's religion,
Down on her knees... etc.
So it's part of a list of what the kids are to them. (And it was mostly written before Monte was born, I think, which is why most of it refers to one child rather than both.) I took the religion reference as coming from the fact that she was on her knees, as if in prayer, so he made the association back from that image.
Edited to become coherent, since I can't keep up with the thread now.
