Much confusion could be avoided here by simply acknowledging the Apostolic Truth that God is ONE. The Holy Spirit is the Spirit of God-the Spirit of Christ. Jesus promised that the comforter would come.
Joh 14:17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him;
for he dwelleth with you, and shall be in you.
Joh 14:18 I will not leave you comfortless:
I will come to you.
