For the first time in its history, the United States does NOT have a Protestant majority.

A new Pew study says percentage of Protestant adults in the U.S. has reached a low of 48 percent, the first time that number has fallen below 50 percent.

There are no Protestants on the U.S. Supreme Court and Republicans have their first presidential ticket with no Protestant nominees.

Among reasons cited for this shift are the growth in nondenominational Christians and a spike in the number of U.S. adults who say they have no religion.

What do you make of this shift? Are you encouraged? Concerned? What does it say about the church and about America?
