So necromancy is no longer in error?
Where does God’s word make that declaration?
You have no way of knowing whose spirit is with the Lord, and attempting to contact any departed one is forbidden in God’s word.
I did not say that. Your attempt to put words in my keyboard is noted. I hold in contempt, folks who do that.
You have no way of knowing whose spirit is with the Lord,
Perhaps you recognize no way of knowing such. That's OK, I guess, although it does unnecessarily limit you. Pity.
I certainly have no way of knowing that any specific soul is damned; I believe that God does indicate to us that certain souls are with Him in Paradise.
