“The biblical truth is there aren’t any “ghosts” only demons masquerading as people who have died in order to deceive, terrorize or demonically indwell or enslave the living.”
Was Moses - who had most definitely died a millennium earlier - trying to “deceive, terrorize or demonically indwell or enslave the living” when he appeared with Christ and Elijah on Mount Tabor? See Mt 17:1-9, Mark 9:2-8, Luke 9:28-36.
Who said Moses was a ghost on the Mount of Transfiguration?
