My "take" is that Obama is a deeply compassionate man, has worked as a community organizer for catholic groups, has attended a local protestant church in Chicago (rev Wright) and it's my understanding that he does get some religious counsel privately at the White House...clearly he sees govt as a player in folks lives...health care being the most obvious example..but his faith based generosity to non profits is an issue....his support of  safety net legislation...a major factor.

I think Obama has a considerable respect for the diverse faiths of all citizens and wants to protect that .....

I don't for a moment think that he is not deeply religious....but very low profile about it, perhaps because he sees it as a deeply personal issue....and as President he's not interested in emphasizing his individual religious commitments. I would guess post presidency, he may well connect up with a specific religious group. Or perhaps not.
