The trinity doctrine claims that the Holy Spirit is another person because the Bible shows the Holy Spirit has mind, will and emotions. But this is unbiblical and faulty logic. The Holy Spirit has a personality because God has a personality. In giving us His Spirit God gives us Himself and so His Spirit has “His” mind, will and emotions the same as man.
The book of Job says, “there is a spirit in man: and the inspiration of the Almighty giveth them understanding.” Job 32:8. A spirit is the part of a person that can be grieved. Daniel explains, “I Daniel was grieved in my spirit in the midst of my body,” Daniel 7:15. A spirit is the part of a person that can perceive or understand things. In Mark's gospel we read, “And immediately when Jesus perceived in his spirit that they so reasoned within themselves, he said unto them, Why reason you these things in your hearts?” Mark 2:8. A spirit is the part of a person that can be troubled. The king of Babylon had a dream and he told his wise men, “I have dreamed a dream, and my spirit was troubled to know the dream.” Daniel 2:3. So we find that our spirit is our mind, will and emotions. This does not make our spirit another person.
What would you think if I said, “I know that we have met before, but have you met my spirit? I would like to introduce you to my spirit who is sitting over there on that chair.” You would obviously think I had a twisted concept of what my spirit is. It is not some other person that is separate and distinct from me. My spirit is who I am and hence is my mind, will and emotions.
The Bible mentions several types of spirits. We find “evil spirit,” “dumb spirit,” “unclean spirit,” “foul spirit,” “humble spirit,” “excellent spirit,” “good spirit,” “broken spirit,” “wounded spirit,” “faithful spirit,” and “haughty spirit” etc. All these spirits are distinguishable by the adjective that describes them such as good, foul and humble etc. We know that God the Father has a spirit (Matthew 10:20) and His Spirit of course could be nothing other than Holy. The word “Holy” is also an adjective be it in English or Greek. So “Holy Spirit” is not a name but a description of God's Spirit.
God the Father and His Son Jesus Christ have different names and titles in the Bible because they are personal beings. If the Holy Spirit is a personal being co-equal with the Father and Son as the trinity doctrine teaches, then why doesn't it have a personal name also?
The “Spirit” is not a name, it is what it is. “Holy” is just the adjective that describes God's Spirit, and other terms such as the “Spirit of God” is not a name either but what it is. It is the Spirit of God! It is also called the “Spirit of your Father” which once again is just what it is.
So if the Holy Spirit was truly a personal being then why no personal name?
