“I got to thinking, how would the biblical Mark that we will someday not be able to buy or sell without, actually work?”
E-verify is a method used to enforce immigration laws. Rand Paul is trying to get some attention. You can define and reduce anything into oblivion.
You could apply Paul’s same argument as a reason to not use computers. Or not use computers because of the alleged mark of the beast.
The mark of the beast was a concept in use during the days when John wrote about it. You could not buy or sell until you when down to their “courthouse” and signed allegiance to the emperor, or offered sacrifice to him. The emperor was regarded as divine.
