"So there is unanimous PREXAD agreement with regard having found no definitive Biblical or Ellen G White prohibition to ordaining women to the ministry."

Bill, I think you are misreading what that is saying. It essentially says the same as the 1990 voted statement. It's acknowledging the situation that some concluded that it's affirmed, and some concluded that it's denied, and that they couldn't come to agreement on the question. There was no consensus. Lns. 20-25 on p. 2 of your link (and other portions of the same) make that clear.

With that being the situation, how else should PREXAD have worded the motion, which required each delegate to harmonize their vote with their study of the Bible and SoP?
