As we see in the rest of the Saul saga, he was not saved, disobeyed, and under Satanic influence attempted to murder the ancestor of Jesus kingly line, with the idea that thus the Messiah could not be born as the Godhead intended. Saul was not a spiritual man, and none of his prophetic utterings have been saved, AFIK. No, the oilation did not impart the Holy Spirit. He was conferred by the Godhead later, after the lubrication phase, and that only temporarily.
"But the Spirit of the LORD departed from Saul, and an evil spirit from the LORD troubled him" (1 Sam 16:14 AV).
I don't see him being de-anointed, for he was still King until death, when the kingdom incrementally passed to David, the pre-anointed king-in-the-wings.
I don't think your equation is balanced. Oilation does not equal Spiritualizing.
Saul was not a spiritual man, and none of his prophetic utterings have been saved, AFIK.
Saul was a spiritual man and the scriptures record some of his words. The scriptures say the Spirit of the LORD came upon him and his heart was changed.
However Saul did not continue to obey the LORD. Because Saul did not continue to obey the LORD rejected Saul as King over Israel. The LORD then chose David as King and the Spirit of the LORD came upon him after his anointing as well.
And the Spirit of God came upon Saul when he heard those tidings, and his anger was kindled greatly. And he took a yoke of oxen, and hewed them in pieces, and sent them throughout all the coasts of Israel by the hands of messengers, saying, Whosoever cometh not forth after Saul and after Samuel, so shall it be done unto his oxen. And the fear of the Lord fell on the people, and they came out with one consent. And when he numbered them in Bezek, the children of Israel were three hundred thousand, and the men of Judah thirty thousand. And they said unto the messengers that came, Thus shall ye say unto the men of Jabeshgilead, To morrow, by that time the sun be hot, ye shall have help. And the messengers came and shewed it to the men of Jabesh; and they were glad. Therefore the men of Jabesh said, To morrow we will come out unto you, and ye shall do with us all that seemeth good unto you. And it was so on the morrow, that Saul put the people in three companies; and they came into the midst of the host in the morning watch, and slew the Ammonites until the heat of the day: and it came to pass, that they which remained were scattered, so that two of them were not left together. And the people said unto Samuel, Who is he that said, Shall Saul reign over us? bring the men, that we may put them to death. And Saul said, There shall not a man be put to death this day: for to day the Lord hath wrought salvation in Israel. Then said Samuel to the people, Come, and let us go to Gilgal, and renew the kingdom there. And all the people went to Gilgal; and there they made Saul king before the Lord in Gilgal; and there they sacrificed sacrifices of peace offerings before the Lord; and there Saul and all the men of Israel rejoiced greatly.
And Samuel said, Hath the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? Behold, to obey is better than sacrifice, and to hearken than the fat of rams. For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the Lord, he hath also rejected thee from being king.
Then Samuel took the horn of oil, and anointed him in the midst of his brethren: and the Spirit of the Lord came upon David from that day forward. So Samuel rose up, and went to Ramah. But the Spirit of the Lord departed from Saul, and an evil spirit from the Lord troubled him.
