Jesus never, ever said: I and the Father and the Holy Spirit are ONE GOD.
Jesus never, ever said: The Holy Spirit is A SEPARATE PERSON.
Jesus never, ever said: The Holy Spirit would be seated with Him and the Father on GODS throne.
Jesus never, ever said: The Holy Spirit would RETIRE.
Where is The Holy Spirit when St John said: In the beginning was the word, and the word was with GOD?
Jesus said: ‘I am ascending to my Father and your Father, to my God and your God.’” John 20:17.
