I don’t refer to those alive in Christ as “non-living.”
I couldn't agree more...and it's a wonderful thought.
All I am saying is that there is an admonition not to involve oneself in necromancy (etc.) and that seems to include all spirits of the non-divine (ref: Saul trying using the Witch of Endor to summon the Prophet Samuel).
Certainly Samuel was with the Father, Son, and Holy Spirit in Heaven (though this of course occurred before the time in which Jesus had come to the earth in person as the Christ).
As an aside, my head is beginning to spin and I think I need a cup of tea.;-)
