My understanding of the the use of the term “trinity”( the term is not in the Bible) is that it is an attempt to get a handle on the total divine attributes of the Godhead...Son, Spirit and Father yet I believe the term to be weak and only a very general one.
Christ said that “I and the Father are one” and John chapter 1 clearly defines God the Father as being the “word” and defines Christ as “the Word made flesh”. We also find that the Spirit of God, “blows where it wills”and “doesn’t refer to himself but rather searches out the deep things of God” and brings them to consciousness in a believer, (yet will never contradict anything in scripture”).
The Father will say, says, and has said..”I will Raise Him UP, I Raise him UP, I have already raised him up”( Denoting the transtemporal omnipresence of God the most High)
The Son says simply “I am risen...I am Alpha and Omega, the first and last!” (denoting his present reality as our advocate with the Father, and the fount from which the Father’s grace flows to those who have humbled themselves)
As for the Spirit, he says simply “He IS risen indeed” and is that empowering manfestation of God’s spirit and power in the life of the Believer... he is our comforter, as promised by “God AS and In Flesh” before he ascended into heaven.
To the extent that the Godhood could ever have fully died, it did so on that cross at Calvary. The term “trinity” could never explain that fullness of unity between Spirit,God in Flesh, and God the most High....what human understanding could ever comprehend the desperate grace poured out for us....YHvH as you call him has loved this world with a desperate kind of love so much so that his own “elect one” in obedience to that love came and died for us. I think it is better to believe and accept the wholeness of the relationship between Christ, Spirit, and Father than to get into tizzies about the various “Parts”. The Bible has called Christ God; he says “I and the Father are one, who ever has seen me has seen the Father”. I think that is all we need to know and understand.
God the Father when pouring out his wrath on the Son on the cross, was pouring it out on himself as well...there was never disunity. When Christ cried out in the throes of death, “Why have you abandoned me”, it was his physical flesh reacting to impending total shock and vascular collapse...I’ve seen such physical emotional reactions in my patients as they neared death. These patients, looking fearful, often reach out looking for a hand, a friendly voice, a comforting hug. Thus our Christ, also, suffered in such a way. Yet he was never alone; the Father and Son were one even in Death hence the earth quaked and the skies grew dark, many of the dead saints of old came out of their graves, and the temple veil was rent...the very powers of creation and Heaven were shaken, and the keys of death and hell were wrested from the EVIL ONE and the power of sin to chain men was destroyed for those who believe!
Then on the third day...Raised alive, his body seeing no corruption as the Father had promised thru prophets of old and thus remains risen to this day.....INDEED!
There’s your Trinity; the term can scarcely begin to describe the reality of God and no human mind in our present darkened state could ever grasp HIS nature. The fact that he has had any regard for man at all speaks to his Glory and Love!
I would agree if you said "fully grasp."
The Church in response to heresy about who Christ is mostly focused on what the Apostolic Church knew He is not. That is the most reasonable approach in light of your statement above. What was described, most fully at Chalcedon, is the Most Holy Trinity; not Unitarianism, certainly not some 1960s-speak such as " shekinah of YHvH in human flesh."
I agree that it is impossible to fully define God in words, but we use words to transmit the orthodox faith and preserve it for 2,000 years and counting. The safest ground here is to stick closely to the Chalcedon Definition. It was not arrived at casually or lately.
Thanks very much for your thoughtful reply.
