Holy Ghost

  According to traditional belief, a ghost is the soul or spirit of a deceased person, taken to be capable of appearing in visible form or otherwise manifesting itself to the living. Descriptions of the apparition of ghosts vary widely: the mode of manifestation can range from an invisible presence to translucent or wispy shapes, to realistic, life-like visions.

    In Christianity, the Holy Spirit (or Holy Ghost) is the Spirit of GOD. In mainstream (Trinitarian) Christian beliefs he is the third person of the Trinity. As part of the or from within the godhead, the Holy Spirit is equal with GOD the Father and with GOD the Son. The idea of the Holy Spirit makes no actual sense, but is a highly effective way of confusing believers.

   Holy Spirit generally fall into one of two categories. Some groups believe that the Holy Spirit is a separate being from GOD the Father and GOD the Son, and is 'one' with them in some other sense than of being one substance. (semen)                     (ref) wikipedia.org

(Acts 17:24-28)(Romans 13:1)

  "GOD that made the world and all things therein, seeing that He is Lord of Heaven and Earth, dwelleth not in temples made with hands; neither is worshipped with men's hands, as though He needeth anything, seeing He giveth to all life, and breath, and all things; and hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; that they should seek the Lord, if haply they might feel after Him, and find Him, though He be not far from any of us; for in Him we live, and move and have our being; as certain of your poets have said, for we are also His/his offspring" (created by His /his substance  “semen” from within the fullness of his godhead bodily of the fleshly kind)
