Since there are always innumerable commentaries expressing confusion over the Trinity concept, I wish to provide a very simple description on the matter.
As above, so below. The Almighty is the Creative Source of all that exists above, which establishes the principle from which what is below forms itself. We can also call what is above the original, and what is below only a coarse reflection. No matter what words we choose, the principle holds. With regard to the Trinity above, the principle also manifests below on the human level, albeit as a coarse reflection. Here is a picture to bring it to life. Broadly speaking, every human on earth is a trinity: Person – intent – will. The human spirit is the central personality, there is the intent that is the core objective informing his deeds, then there is the will that executes the intent of the said personality. The intent and the will are individual workings that are still unified in the central personality. The intent expresses itself through the will, and the will itself carries and expresses the intent. But both are just the nature of the activity of the human spirit.
Father – Son – Holy Spirit
The Father is the central personality; the Son of God is the Love of God who carries the intent of the Father; and the Holy Spirit is the Executive Will who creatively carries out and manifests the objective of the Father in tangible form. The Holy Spirit carries the intent, for He bears the Love of God within, yet He expresses it through creative deeds. The Son of God and Holy Spirit are two distinct Personalities unified in the Father.
When God wished to create the worlds, as this activity was an Act of Will, then the task had to be carried out by His Executive Will, The Holy Spirit. “In the beginning God created the heavens and the earth. And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.” Ergo, the Holy Spirit is the “Let there be Light” from out of God. As He is the beginning, it logically follows that He also is the end, i.e. the Alpha and Omega. As He is the Will who brought about the beginning, then He alone is the one who can bring about the end through a final judgment and a purification that makes all things new.
The Holy Spirit is the Son of Man, while Jesus is the Son of God. This is a simple concept that has been misunderstood and mistranslated for centuries. But what makes the Holy Spirit the Son of Man? Simple: As He is the Will of the Father who created the Universe and also the human spirit, the human spirit is His work. Thus, He is that Son (outborn of the Father) through whom man (the human spirit) came into existence. Thus, the Son of Man.
When Jesus spoke about the Promised Son of Man, He was referring to another Divine Personality, not Himself. He was referring to the Mission of the Spirit of Truth, the Son of Man. This has never been clearly understood, and that is why all attempts to synonymize the Son of God and the Son of Man into one Person is always unsatisfactory. They are two different personalities, with two different names, who have two different Missions. Howbeit, as they are both one in God the Father, their Teachings will naturally harmonize, hence the statement [John 14:26] “But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.”
As the Son of God was born into the earth, so will the Son of Man be born into the earth for His Mission.
These explanations are naturally not exhaustive, but were intended to shed some light on the concept of the Trinity, and highlight just a few differences between the Son of God and the Son of Man. But there is more to it.
