True, they are Postmillennialists, but there is more to "Dominion Theology" than that. In keeping with their postmillennialism, they believe Premillennial Christians (who believe Christ will return BEFORE the millennial) have got it backwards, the world is NOT getting worse and worse, it is actually getting better and better. Yeah right.
Scripturally speaking, Dominionists are out in the weeds big time.
I was trying to be brief and then somewhat amusing.
