Not in the way the author means. It has more likelihood to become a Muslim, not a Christian/Jewish, theocracy the way we are going.
Absolutely correct.
I have worked among virtually every sect/type of Christian group and the ultra-Christian Dominionist and Reconstructionist movements are a tiny minority of Christians. And, not that influential for their numbers.
A bridge too far, for sure.
The New Testament has no mandate for the construction of a Christian government short of the return of Jesus Christ in person, so any attempt to construct one is by definition extrabiblical. You’d certainly get a grand fight against this concept by most mainline fundies, including the Southern Baptists.
