To be truthful, Icemoon has professed once, i read somewhere,
that he is not a Christian, most likely he is just well versed in
the theology without publicly acknowledging which one he leans on
or find the most believing.
As for brey, he has a Jewish wife, and would have greater
understanding of the Jewish culture and Judaism than most of
us.
And as for MC, as his twin brother... 
.. I like to say, MC is a faithful Christian. As
for what's troubling him, look at his signature. I like this
description somebody gave about MC, I think its babyss, who said,
MC is someone who may not go to church, but faithfully hold onto
his cross and places his faith on God.
