Is the U.S. a Christian Nation?

Sociologist Dr. William Martin -- the author of the excellent history of the rise of the religious right, With God on Our Side: The Rise of the Religious Right in America -- recently debated the question Is the US a Christian Nation? on Opposing Views.

Dr. Martin's careful approach to the debate is exemplified in his first comment -- What Do You Mean By That? -- in which he clarifies the question and his position.
