The Word = the logos of God, the mind of God. Jesus had a fleshly brain. The mind of God/thought life of God was housed in a human brain.
Don't limit God's power by saying what God cannot do. As Jeremiah reported, God says, "Behold, I am the Lord, the God of all FLESH. Is anything too difficult for me?"
You write: ‘The Word = the logos of God, the mind of God. Jesus had a fleshly brain. The mind of God/thought life of God was housed in a human brain.’ Are you suggesting that the only part of Yeshua that was God was his brain?
Let’s be a lot more serious: Your claim that God ‘housed’ Himself in a human body is a deliberate corruption of the text.
You know perfectly well that the author of ‘Yochanan’ does not say that the Word was ‘housed’ in flesh; he states that the ‘Word’ became flesh. This is quite a different matter.
We are agreed that God is immutable. If He is truly immutable then He cannot change. If indeed He can change, but chooses not to, then He is not immutable. We can’t have it both ways.
And the problem remains: How is it possible for God – an immutable Being – to become a human being? The Church is well aware of this problem, of course. This is what Ludwig Ott has to say:
‘…..it is objected that the Hypostatic Union contradicts the immutability of God. The rejoinder to this is that the act of becoming man, as an operation of God ad extra, has no more induced a change in the Divine Essence than did the creation of the world, as it is only the execution in time of an eternal unchangeable resolve of will. Neither did the event of the Incarnation result in a change of the Divine Essence; for, after the assumption of a body the Logos was no more perfect and no less perfect than before. No change for the worse took place, because the Logos remains what It was; and no change for the better, because It already possessed in sublime manner all perfections of the human nature from all eternity.’ (‘Fundamentals of Catholic Dogma - Chapter 4 - Theological-speculative Discussion on the Hypostatic Union’).
Let’s examine this statement more closely:
First: That the act by which the ‘Second Person of the Trinity’ (the ‘Logos’) became a man is no different from God’s act of creation; since both are merely ‘the execution in time of an eternal unchangeable resolve of (His) will.’
I know of no Trinitarian who believes that when God created the universe - and all that lies therein- He actually became this universe; this galaxy; this planet; this rock; this tree; or that He became ‘Adam’. On the other hand, every Trinitarian believes that the ‘Logos’ was made flesh.
The act of creation and the (alleged) act of Incarnation are entirely different as to their natures. The former required no change to the essential nature of God. The latter, on the other hand, could not have been achieved without change (a change from spirit to flesh).
Second: That following ‘the event of the Incarnation’ the ‘Logos’ was ‘no less perfect than before (and that) no change for the worse took place, because the Logos remains what It was.’
The Nicene Creed confesses: ‘’Who for us men and for our salvation descended from heaven and was made flesh’ (Denzinger 86). To say that the ‘Logos’ was: ‘no less perfect’ after becoming flesh that it was beforehand is to say that God and man are equal in their perfection; in their holiness; in their very natures.
The nature of God: He is spirit…………He is immutable…….He is infinite………He is omnipotent…………He is not man!
The nature of man: He is corporeal…..He is mutable…….He is finite……..He is weak……..He is not God!
How can these two natures be the same? How can a change from the former to the latter not be a change for the worse?
Third: That the ‘Logos’: ‘Already possessed in sublime manner all perfections of the human nature from all eternity.’
Really? In what way can a being that is ‘absolutely simple’ (declared as such by the 4th Lateran Council and the First Vatican Council; see Denzinger 428, 1782) – a pure spirit; being neither a body nor a composition of body and spirit – possess, in any way, and to any degree, a corporeal nature?
Ott goes on: 'The change lay on the side of the human nature only, which was elevated to participation in the Personal Subsistence of the Logos.’
In other words, instead of the ‘Word’ becoming flesh, the flesh became the ‘Word’ (to use your analogy, it was not God who became the ‘tent’; it was the ‘tent’ that became God).
Yet another, blatant, corruption of Yochanan: 14.
Council of Basel decreed that it: ‘Holds, professes and teaches that one and the same Son of God and of man, our lord Jesus Christ, is perfect in divinity and perfect in humanity; true God and true man, of a rational soul and a body; consubstantial with the Father as regards his divinity, consubstantial with us as regards his humanity; like us in all respects except for sin; begotten before the ages from the Father, and in the last days the same born according to his humanity for us and our salvation from Mary the virgin mother of God.’ (Session 13).
We are assured that: Christ is ‘perfect in humanity’….a ‘true man’…..‘consubstantial with us as regards his humanity’…..‘like us in all respects except for sin.’
The Council of Chalcedon also declared Yeshua to be ‘truly God and truly man’ (Denzinger 148).
John Hick writes: ‘(The Council of Chalcedon) merely asserted that Jesus was ‘truly God and truly man’ without attempting to say how such a paradox is possible…. Merely to assert that two different natures coexisted in Jesus ‘without confusion, without change, without division, without separation’ is to utter a form of words which as yet has no specific meaning.’ (‘The Metaphor of God Incarnate’; page 48).
You appears to argue that ‘all things are possible with God’; that He can do whatever He pleases; but this is not correct.
God can do nothing that is against His essential nature. For example, He cannot make Himself smaller, since He is absolutely infinite; He cannot make Himself ignorant, since He is Omniscient; He cannot will Himself into oblivion, since He is Eternal; He cannot change His essential nature, since He is absolutely immutable; He cannot sin, since He is Holy.
C.S. Lewis (a confirmed Trinitarian) writes: ‘(God’s) Omnipotence means power to do all that is intrinsically possible, not to do the intrinsically impossible. You may attribute miracles to Him, but not nonsense. This is no limit to His power. If you choose to say "God can give a creature free will and at the same time withhold free will from it," you have not succeeded in saying anything about God.
‘Meaningless combinations of words do not suddenly acquire meaning simply because we prefix to them the two other words "God can."… It is no more possible for God than for the weakest of His creatures to carry out both of two mutually exclusive alternatives; not because His power meets an obstacle, but because nonsense remains nonsense even when we talk it about God.’ (The Problem of Pain). My emphasis.
Lewis is saying that God cannot do what is logically impossible; and in this he is supported by Aquinas, who writes that God cannot create a man who is, at the same time, a donkey; for in the statement that a man is a donkey ‘the predicate is altogether incompatible with the subject.’ (cf. Summa Theologica: Part 1; Question 25; Article 3).
E. P. Sanders writes: ‘It lies beyond my meagre abilities as an interpreter of dogmatic theology to explain how it is possible for one person to be 100 per cent human and 100 per cent divine, without either interfering with the other.’ (The Historical Figure of Jesus’; page 134.).
And so the question remains: ‘How is it possible for a being to be both wholly God and wholly man at one and the same time?’
