For those who want to take a crack at this topic, remember that the question I'm asking is what the medium and Saul actually saw or experienced, not whether the "ghost" was actually Samuel.
The apparition was not Samuel because Samuel was dead. Persons who have ceased to exist in this life cannot have contact with this life.
1Samuel 28:7
Then said Saul unto his servants, Seek me a woman that hath a familiar spirit....
The original Hebrew for "familiar spirit" conveys the word "ventriliquist". The woman was a fraud deceiving naiveve persons in order to make money.
1Samuel 28:11 and partial verse 12
Then said the woman, Whom shall I bring up unto thee? And he said, Bring me up Samuel.
And when the woman saw Samuel, she cried with a loud voice....
This is how we know she was a fraud. As she went into her routine an apparition appeared which she did not expect to see. This is why, verse 12, above, says, she "cried with a loud voice". The ventriliquist at Endor was shocked that a genuine supernatural event actually occurred.
Here is what is going on:
In context: The O.T. exists within the context of the Fall and Satan has right of control. Saul was judged by God for failing to execute judgement on Amalek the way God ordered him to. Instead of falling on his face and seeking God's mercy (like David did when he sinned) Saul didn't care. Now he is in trouble with the Philistines approaching and he still won't drop everything and seek God. Even though the Scriptures say God would not answer Saul that meant God would not do so on Saul's schedule. Instead, Saul shows his spiritual state to be aligned with the occult/Satan.
Here is what happened at Endor:
Demons wanted to secure Saul's soul. When he opened himself up to their area of domain Saul was subject to their supernatural deceptive powers. The apparition was real and it was a demon impersonating Saul. All the apparition did was to repeat what Samuel told Saul after he failed to destroy Amalek. Those words of judgement had the sting of God's authority because the original words from Samuel were from God. IOW, the demon simply reminded Saul of what God said through Samuel HOPING to make Saul forever give up on God.
The Scriptures recording of Saul's end portrays a person who believed the demon.
