66 percent of evangelical adults favor a constitutional ammendment making Christianity the official religion of the U.S., according to a Barna survey. While a majority of evangelicals favor such a move, only 32 percent of adults in general favor the move.
The survey explored a number church/state issues, in most cases finding favor for Christian principles, though few favored official support of Christianity. Support for removing the 10 Commandments, “In God We Trust” and “one nation under God” was between 15-18 percent, while support for teaching creationism was at 59 percent.
