If you mean a new Israel or a covenant nation, Southern Baptist leader Russell Moore — writing for The Gospel Coalition — says no.
The Founders were influenced by Christians but there is no religious test in the Constitution. Moore says the Bible doesn’t assign America a providential place in history. Moore makes it clear that Ted Cruz’s stump verse of II Chronicle 7:14 was a promise to Israel and not to America as a political entity.
While Moore didn’t call out specific people, this is a pretty clear rejection of David Barton’s Christian nationalism on theological grounds.
