You claimed that the support fro your position comes from that passage that you took out of context (which is actually about whether the dead are resurrected) about God being "God of the Living" (despite the fact that Deut 18 condemns communication with those who are dead in the flesh).
So your position is inconsistent. If you are saying that it is okay to communicate with those who are dead in the flesh because they are actually alive. Then one of those point that I stated must be true of your beliefs. Otherwise you are presenting a contradictory position.
