None of those show me how there can be three co-equal, co-eternal, co-existent gods that make up one deity? How can one God have all power but share it equally with two others? How can Jesus pre exist (as trinitarians believe) and still be born of a virgin? “I am God, and beside me there is no other.” Sounds pretty clear to me. He said that no man can see him and live, and He had to fulfill the law and the covenant so made a human body that he put on like a robe and walked this earth for 33 years and died to redeem us from our transgressions. We could get into the discussion on if Jesus could have sinned. I bet that would get entertaining.
Well your first sentence shows you do not understand the trinity. The doctrine of the trinity does not say there are three gods. There is one divine nature God, in three co-equal, co-eternal persons: God the Father, God the Son (Jesus Christ), and God the Holy Spirit. These three persons share one essence or nature, but are distinct in their roles and relationships.
These roles and relationships are what we see directly in the scriptures.
The Father Initiates and directs the plan of salvation, sends the Son and the Holy Spirit, is the source of all things
The Son (Jesus) becomes incarnate and redeems humanity through his life, death, and resurrection, is the Word of God and the means by which creation was made, and Intercedes for humanity.
The Holy Spirit empowers believers to live according to God's will, convicts, teaches, and leads, and sanctifies and dwells within believers.
Additionally in the scriptures we see each person of the trinity is individually given the honors, attributes, names, deeds and seat of God.
Now we as limited humans do not fully understand how this works. We in no way could fully understand how the inner workings of the eternal relationship of the God head. It is rather arrogant to assume that you could fully understand God in that way. There is no logical contradiction that exists and we see the tenants of the Trinity in scripture, so we embrace the mystery.
Now to Jesus. He is the eternal Son who is fully divine. During the incarnation he took on human nature. He is now both fully God and fully man in one person without confusion or separation. This is called Chalcedonian Christology or the hydrostatic union. Without his fully divine nature he could not have lived a sinless life. Without his fully human nature he could not have been our representative, the new Adam, that atoned for all man kind.
