Whew! I just finished all 8 of your most recent posts on The Trinity Heresy in one sitting!
I am super impressed and for the first time in many years may be experiencing a significant upgrade in my understanding of Jesus. For that I thank you.

It almost didn't happen though. I must admit that I found your writing style so off-putting, so offensive, so insulting, so unnecessarily accusatory and confrontational that I almost threw it aside (to my loss) many times in the past two hours. It was only the grace of God, my intense interest in the subject matter, and the fact that you were masterfully making your case based solely on Scripture that caused me to persevere.

You might want to work on your bedside manner, doctor, if you expect to heal anyone.
For now, I will simply write it off to the intensity of your passion for your subject.

Allow me now to humbly attempt to return the favor, as iron sharpens iron.

Consider how Jesus spoke to Phillip when he said, "Show us the Father." As I recall, Jesus said something like, "Phillip you double minded, cherry picking, trinitarian hypocrite! How dare you misunderstand Me. You are hereby damned for all time!"

Oh, wait, he didn't say that did He? It was more like a gentle father rebuking a child for not thinking clearly, "Philip, I have been with you all this time, and still you do not know Me? Anyone who has seen Me has seen the Father. How can you say, ‘Show us the Father’?

What about the thief on the cross? Did Jesus interrogate him about the fine points of his theological understanding of the relationship between the Father and the Son? Um, no. “Jesus, remember me when You come into Your kingdom!” And Jesus said to him, “Truly I tell you, today you will be with Me in Paradise.” I wonder how many of your advanced concepts were in that new believer's mind at the time that promise was made.

And of course there is Romans 14 and Paul's rebuke: "Accept the one whose faith is weak, without quarreling over disputable matters." and "Who are you to judge someone else's servant? To their own master, servants stand or fall. And they will stand, for the Lord is able to make them stand."

Anyone who is acting like a good Berean and "diligently searching the Scriptures to see whether these things are so" is a loved and valuable servant of Christ and does not need to be rebuked with vitriol when they use a slightly improper metaphor to describe the mystery of God.

Misquoting Paul to drive home the point:
Therefore let us stop passing judgment on one another. Instead, make up your mind not to put any stumbling block or obstacle in the way of a brother or sister. ..Do not by your [harsh rhetoric] destroy someone for whom Christ died. Therefore do not let what you know is good be spoken of as evil. For the kingdom of God is not a matter of [theological metaphors], but of righteousness, peace and joy in the Holy Spirit, because anyone who serves Christ in this way is pleasing to God and receives human approval. Let us therefore make every effort to do what leads to peace and to mutual edification.

And how did our Lord address Peter when he proclaimed Who He was? Simon Peter answered, “You are the Christ, the Son of the living God.” Jesus replied, “Blessed are you, Simon son of Jonah! For this was not revealed to you by flesh and blood, but by My Father in heaven.

Nope, I don't see Jesus rebuking Peter here for not correctly articulating that he was in fact the Father Himself wrapped in human flesh. Instead, he affirmed the still limited understanding that Peter had just received.

Returning to your substance of your arguments:

A couple days ago as a classic Methodist "Trinitarian", I posted this: Jesus is the God of the Old Testament

At no time did my nominal Trinitarian working model of God prevent me from recognizing Who Jesus is. As I read your "Heresy" series I kept looking for something I disagreed with. Despite the volumes you wrote about it, your whole argument seemed to hinge on an objection to the meaning of the word "Person".

Is a member of the Star Trek Borg collective a person? Or is the hive mind the person and each instance of that mind one of its "right arms"? The individuals seem to communicate with each other while simultaneously knowing each other's thoughts while offloading some of the thinking workload among the individual instances. Is the Borg hive mind one train of thought or a massively parallel collection of somehow integrated thought trains?

I'm not saying that God Almighty is in any way like a Borg collective. I'm just saying that proper understanding the word "person" in the context of God can fail 99% of God's children -- and the most they are likely to get for it is a soft rebuke like Jesus gave Phillip or more encouragement like He gave Peter.

Are you really saying that while God is using His right hand to "animate" the incarnation of His Son He is not equally able to allocate any number of independent trains of thought to that same appendage giving it the appearance and actual fact of "thinking for itself"? Can He not have a separate Linux style "process" totally dedicated to "Helping" each and every one of His children? How, exactly, would our limited minds perceive the "process" that is interacting with us if not as a unique person, omnipresent or not?

How do you know which model of God's thought processes are correct, given that His thoughts are higher than your thoughts? Should we foolishly attempt to model them as massively parallel or single threaded? If they are massively parallel, why can't a simple minded Child of God think of each instance as a Person? Might God not laugh at your puffed up opinion of your slightly better mental model of His mind just as well, saying "Who is this that obscures my plans with words without knowledge? Brace yourself like a man; I will question you, and you shall answer me. Where were you when I laid the earth's foundation? Tell me, if you understand."

You've got some great material here, soundly rooted in Scripture. If you want to communicate those insights to all the Children that Christ died for, I suggest you consider what Peter himself might tell you:

"Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect." 1 Peter 3:15
