Here's an option:

God expects us to evolve, and, as we do, we will no longer need things like second-eyelids, webs on our hands and feet, arms, legs, and, thumbs. We will be able to control everything with our brain.

Maybe, God spoke to these people of their eventual outcome. A bunch of brains floating in a room, mentally stoning another who doesn't follow the rules.

If we skip all this "evolving" stuff, and look to distinguish every person by their brain...

What a world we live in.
