What are his commandments?

Not exactly. It's so we're aligned with the Holy Spirit's will.

Is Holy Spirit God to you?

You quoted from 1 John. John identifies the two commandments in the same letter, 1 John.

1 John 3:23-24
This is His commandment, that we believe in the name of His Son Jesus Christ, and love one another, just as He commanded us. The one who keeps His commandments abides in Him, and He in him. We know by this that He abides in us, by the Spirit whom He has given us.

Obviously, these two commandments will have the supremacy.

Splitting hairs. God=Holy Spirit. Actually doing the will of the Father is what Christ was talking about when people brought His family to His attention.

Yes, of course. Under the new covenant God works through the Holy Spirit, not the old written laws and commandments.

"The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit." John 3:8

Is Gods triune nature divided against Himself?

This is definitely one of them:

John 13:34-35

"A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another."

John 15:10-14

"If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love. These things have I spoken unto you, that my joy might remain in you, and that your joy might be full. This is my commandment, That ye love one another, as I have loved you. Greater love hath no man than this, that a man lay down his life for his friends. Ye are my friends, if ye do whatsoever I command you."

.
5» Rom 6:11 . . Count yourselves dead to sin but alive to God in Christ
Jesus.

"dead to sin" in this case doesn't mean Christ's sheep can't, won't, and/or
don't sin (cf. 1John 1:8-10). It means that sin can no longer give God cause
to slam them with the sum of all fears.

Rom 5:12-21 explains, in so many words; that Christ's believing followers
are accounted as having gone to the cross with him similar to accounting
them as having tasted the forbidden fruit with Adam. (This principle is at the
very core of Christianity's plan of salvation so it's important to get it)

In a nutshell: When Jesus went to the cross; he died for the sins of the
world from first to last. That being the case, then when his believing
followers went to the cross with him, they died for their sins from first to
last. As a result: when the books are opened as per Rev 20:11-15, there will
be nothing on record with which to charge them. (cf. Rom 8:31-34 & 2Cor
5:19)

NOTE: "in Christ Jesus" is a position similar to Noah's position in the ark.
Getting into the ark was a simple physical action, whereas getting into Christ
Jesus requires the assistance of a complex supernatural action. More on that
later; meanwhile suffice it to say that as a position in the ark provided Noah
safety from the storm, so their position in Christ Jesus provides his believing
followers safety from a storm looming on the horizon that's much worse.

I have not been following your discussion, but this is not necessarily true. Some "old written laws and commandments" have carried over into the New Testament.

Here is a rather obvious example:

Ephesians 6:1-3

"Children, obey your parents in the Lord: for this is right. Honour thy father and mother; (which is the first commandment with promise) That it may be well with thee, and thou mayest live long on the earth."

The commandments in the New Testament are much much more all-encompassing than anything written in the Old Testament. There are several type of laws in the Old Testament, but we have to follow all the moral laws/commandments of the Old Testament plus the new commandments (commandments of the heart) covered in the New Testament.

The Letter of the Law is unobtainable. Obeying the Spirit of the Law is obtainable when we receive the Holy Spirit of the Father and Son who fill our hearts with divine love so that the motivation for all of our thoughts and actions is love for God first and everyone else as we love ourselves. That is what happens when we are born again. If it doesn't happen, you are not born again.

Love is the summary of the law.
God is Love.
The law is God's character

The Spirit and the word and Jesus and the Father all reveal and are Love.

The law revealed is the life of Jesus and the word, old and new Testament.

The 10 commandments are the principles of love ....
Love God with all your heart and love your neighbor as yourself.

God doesn't change and the principles of love don't change.
The old and new testiment both teach the laws of love.
By grace the principles of love can be fulfilled in us by the Holy Spirit.

Romans 13:10

.
6» Rom 6:12-13 . . Do not let sin reign in your mortal body so that you obey
its evil desires. Do not offer the parts of your body to sin, as instruments of
wickedness, but rather offer yourselves to God, as those who have been
brought from death to life; and offer the parts of your body to Him as
instruments of righteousness.

That's essentially the same instructions that God passed on to Cain; to wit:

"If you do what is right, will you not be accepted? But if you do not do what
is right, sin is crouching at your door;" (Gen 4:7a)

That's the very first instance in the Bible of the word "sin". The Hebrew word
basically means an offense; as in repeat offender. In other words; not just
an occasional slip-up, but a life style.

"It desires to have you, but you must master it." (Gen 4:7b)

That's the first mention of self control in the Bible. In other words: God
created humanity with the capability to choose bad ways for itself; but that's
only half the story. God also created humanity with the capability to choose
good ways for itself; so He wasn't requiring something impossible from Cain
like touching his right elbow with the thumb of his right hand. So if self control
was within the capabilities of a brutish man like Cain, then I should think self
control would be within the capabilities of Christians too.

I
In spirit means that you cannot keep the law by cutting flesh to complete the law to be circumcised, by not mixing fibers, or by adjusting what we eat. We keep the law by accepting Christ within, by loving God and accepting His ways as our ways.

Rom 13:8-10 Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. 9 For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. 10 Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.

Gal 5:13-18 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another. 14 For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself. 15 But if ye bite and devour one another, take heed that ye be not consumed one of another. 16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh. 17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would. 18 But if ye be led of the Spirit, ye are not under the law.

Not under the law because the Spirit enables you to obey it. You are not under the laws condemnation when you are not breaking it.

Jas 2:8-12 If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: 9 But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors. 10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. 11 For he that said, Do not commit adultery, said also, Do not kill. Now if thou commit no adultery, yet if thou kill, thou art become a transgressor of the law. 12 So speak ye, and so do, as they that shall be judged by the law of liberty.

Rom 8:1-4 There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit. 2 For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death. 3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: 4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.

We are week in the flesh, slaves to the flesh. Thanks to Jesus we can have the Spirit to set us free by faith.

If the Spirit lives in us and controls us we don't sin and the law can't condemn us of sin and claim us as slaves.

Rom 7:5-14
5 For when we were in the flesh, the motions of sins, which were by the law, did work in our members to bring forth fruit unto death. 6 But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter. 7 What shall we say then? Is the law sin? God forbid. Nay, I had not known sin, but by the law: for I had not known lust, except the law had said, Thou shalt not covet. 8 But sin, taking occasion by the commandment, wrought in me all manner of concupiscence. For without the law sin was dead. 9 For I was alive without the law once: but when the commandment came, sin revived, and I died. 10 And the commandment, which was ordained to life, I found to be unto death. 11 For sin, taking occasion by the commandment, deceived me, and by it slew me. 12 Wherefore the law is holy, and the commandment holy, and just, and good. 13 Was then that which is good made death unto me? God forbid. But sin, that it might appear sin, working death in me by that which is good; that sin by the commandment might become exceeding sinful. 14 For we know that the law is spiritual: but I am carnal, sold under sin.

This is a wonderful edification, and I believe, well worded teaching assembled to be understood by many. God bless you always.

Romans 7:10 first phrase

The commandment(mitzvah), which was for life,....

The commandment was for life and was the Son's path to life and resurrection because of His obedience in giving His life to save us as the commandment required of Him. So the purpose of the commandment being for life was fulfilled and accomplished because of His obedience. Although the commandments show us to be sinners, the Son's obedience saved Him from the death He suffered for us and saves us by what He did.

verse 12

Wherefore the law is holy, and the commandment holy, and just, and good.

Jesus' commandments are to
1) Fear not,
and
2) only believe.
