[The Washington Times] 19 Feb 2008--It's always intriguing to see which churches have grown and which denominations have faded in the past year. According to the 2008 Yearbook of American and Canadian Churches (a Bible of sorts for us religion writers), the fastest-growing religious body in 2007 was the Jehovah's Witnesses at 2.25 percent.

Following them were the Mormons at 1.56 percent and the Roman Catholics at .87 percent. Compare this to last year's states that had the Catholics out front at 1.94 percent, followed by the Assemblies of God at 1.86 and the Mormons at 1.63.

The denomination with the biggest decrease is the Episcopalians at 4.15 percent.
