Yeah, I guess I was trying to figure out if Calvin was saying this could be done by knowledge without faith or not. I.e., does such a thing exist? If "yes" then was their knowledge somehow special such that a non-believer could not be in that boat today? I'm not sure, but I think Calvin would say yes, there was something special about that knowledge. Otherwise, this sin could be committed all the time today.
Would have to ponder that longer and with better capacities than I have readily available today. LOL.
Thx.
