Who Was Riding Upon the Waters?

G. mentioned in passing the other day one of those quirky Mormon teachings that I’ve been curious about for a while: “Satan rules over the water.” The origin of this teaching is Doctrine & Covenants Section 61, in which the elders have to halt a river voyage when they see “the destroyer riding in power upon the face of the waters.” The Lord declared to them, “Behold, I, the Lord, in the beginning blessed the waters; but in the last days, by the mouth of my servant John, I cursed the waters.” D&C 61:14. And then later on: “I, the Lord, have decreed, and the destroyer rideth upon the face thereof, and I revoke not the decree.” D&C 61:19

What I wonder is whether “the destroyer” who rode upon the face of the waters was, in fact, Satan, or if it was instead a destroying angel sent by the Lord, as in the days of the Passover. (more…)
