Barack Obama understands religion in a pluralistic society better than anyone we’ve seen in the White House for years:
He knows his own religion well (Christianity, not Islam), and he uses examples from the scripture in which he believes. However, he also understands that America is a pluralistic society not based on one religion or even one particular variant of that religion. He understands that political goals based on religious beliefs need to be expressable in terms other than just an appeal to religious authority.
He gets it.
