I was asked this question:
Can you comment on the Holy Ghost vs. The Holy Spirit and who Jesus is and who the Father is, etc… Also, is it possible that Jesus is the same Spirit as the Holy Ghost? Moses 5:9
This is fraught with debatable language in the scriptures. There are those who will absolutely disagree with what I have to say. I can explain how I have sorted it out to my understanding, but you should recognize that there are others who would take a different view of the scriptures and of the definition of these roles of the Godhead.
First the clarification:
The Holy Ghost is a personage. It is an individual. It is a Spirit that will dwell inside you. (D&C 130: 22.)
The Holy Spirit is the power of God which fills the immensity of space. (D&C 88: 12-13.)
Now the problem:
Sometimes the Holy Spirit is called the “Light of Christ” rather than the Holy Spirit. (D&C 88: 7-11.)
Sometimes the Holy Ghost is called the Holy Spirit. (Luke 11: 13.)
Whether you are reading something about the Holy Spirit or Holy Ghost is something that must be determined by the context, not the language used.
The relationship between the Holy Spirit or Light of Christ and every living thing, whether a planet, plant, animal, human or ecosystem is direct, immediate and continual. They are all borrowing power from the Holy Spirit to live, move breath, remain organized, and do according to their own wills. (Mosiah 2: 21-25.) This is the means by which the Holy Ghost, which resides inside of you, receives intelligence from Christ.
The Holy Ghost is the “record of heaven” which lives inside you and that you have lost contact with because of the veil. It is a personage of spirit who resides inside you, and you must “receive” it after baptism by finally listening to that inner “truth of all things” or “record of the Father and the Son.” (Moses 6: 61, 66.)
The Holy Ghost bears record of the Son. When the Son speaks to you through the Holy Ghost you hear the words in the first-person. Hence the Holy Ghost speaking that it “is the Son” in Moses 5: 9.
I’m keeping this short because the more I explain the more questions will arise. So clarity on this topic is almost invariably related to brevity.
