Some are saying that the cashless society that is coming, people will have to have some way to buy or sell,(mark of the beast, Protestants claim). However, I am trying to figure out why that would be a sin, although I don't like or approve of it, why is it a sin to exchange goods by this method, isn't that what most do anyway with credit cards.
I think the mark of the beast has always been with us, it is mortal sin, sinning with our mind (forehead) or actions, (hands), yet I do not know, just thinking about these things.
Does anyone here know about Catholic Eschatology?
