Marco Rubio and Christian Eclecticism

This piece is just a few days old but contains some interesting information about Senator-elect Rubio's religious commitments (h/t Mark Movsesian).  According to the piece, Senator Rubio is both a "practicing and devout Roman Catholic" and a committed member of Christ Fellowship, a church affiliated with the Southern Baptist Convention.  

The piece speculates about some political reasons for Senator Rubio's membership in the evangelical church, and it concludes with this: "What may be clear from this story — call it The Case of the First Catholic Protestant Senator — is that in America, religious distinctions matter less all the time."

That last nugget of liberal theology didn't seem to follow from the story.  At one point, the author includes a quote that had Rubio "come out" as an atheist, there would have been serious political trouble.  For that matter, my guess is that he would have been in hot water had he said that he was both Muslim and Catholic.  But it may well be that within Christian communities in the United States -- and perhaps, as the article intimates, particularly among Hispanic-American communities (though I am even less sure about this) -- inter-denominational comfort has increased substantially, and that something more than tolerance, something more embracing, has developed.  Compare, e.g., where the country was 50 years ago, let alone at the founding.  Perhaps a kind of Christian eclecticism is emerging?
