Rationality is certainly a good thing, but as I said before, "Consider the possibility that your 3 lb brain may not have the ability to comprehend this aspect of God."
It wouldn't matter if my brain were INFINITE in size. It could never "comprehend", or accept as true, a statement which is self-contradictory.
“God eternally exists as three persons, Father, Son, and Holy Spirit, and each person is fully God, and there is one God....When we speak of the Father, Son, and Holy Spirit together we are not speaking of any greater being than when we speak of the Father alone, the Son alone, or the Holy Spirit alone.” Wayne Grudem
It could be conceived that the three together are not "greater" in some sense. But surely it must conceded that they are greater in number.
I have already argued that if that is the way God is defined, then the sentence "God was born as a human being" is tantamount to "The Trinity was born as a human being".
If this is not the case, then the word "God" is being used in a different sense in the sentence, "God was born as a human being."
Likewise, if "God" means "The Trinity", then to say "Jesus is God" means "Jesus is the Trinity". If not, then "God" must be used in a different sense in the sentence, "Jesus is God".
So it seems we are just repeating the same arguments over and over, and getting nowhere.
I can see a consistency in a Trinitarian argument only in the way I understand Mattrose to believe in it (but maybe I misunderstand him). Here is the way that argument could go.
1. The Father, the Son, and the Holy Spirit are three divine Persons of the same divine Essence.
2. The word "God" means that divine Essence.
3. Thus the Father is God; the Son is God; the Holy Spirit is God.
4. God is not the Father. For that would exclude the other Two. And God is not the Son or the Holy Spirit for the same reason.
5 . However, we may use the terms: God the Father, God the Son, and God the Holy Spirit to distinguish the Three, each of whom are of the One Divine Essence (i.e. each of whom is God)
6. God is not a Person, but an Essence, and in Itself is impersonal unless associated with one of the three divine Persons.
7. Each time we speak of God as "He" we do not mean the Divine Essence, but we mean one of the members of the Trinity.
6. When we say, "God was born as a human being", we mean "The Son of God was born as a human being" or we may say "God the Son was born as a human being."
If Trinitarians admit that they are using "God" in at least two different ways, and explain how they are using it in each statement, then they can offer a consistent explanation.
Having explained this consistent theory of the Trinity, I am not convinced, because I do not see this in Scripture:
1. Jesus prayed to His Father calling Him "the only true God", and then added "and Jesus Christ whom You have sent" as someone OTHER than "the only true God." If Trinitarianism were true in ANY sense, Jesus, too, would be true God.
2. Jesus also referred to His Father as "the only God" (John 5:44)
3. Paul referred to the "one God" as the Father, and Jesus, not as the one God, but as the "one Lord":
... yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist. (I Corinthians 8:6)
4. In his letter to Titus, Paul also meant the Father when he wrote of "one God". But he referred to Jesus as the mediator between God and men.
1Ti 2:5 For there is one God, and there is one mediator between God and men, the man Christ Jesus...
When Paul spoke of the one mediator between God and man, how was he using the word "God"? Clearly he did not mean an essence, or a Trinity. He meant the Father.
To sum up my own understanding:
1. There is one true God, the Father, the Creator of all things.
2. There is one Son of God, the only-begotten Son, begotten by the Father before all ages. This act of begetting marked the beginning of time.The Father created all things THROUGH His Son. Thus the Son is Deity, and may be called "God" in the sense of His being of the same Essence as the Father who begat Him, just as each of us is human because we were begotten by human beings.
3. Unlike us, the Father and the Son can extend their Personality anywhere in the universe, and they do so, especially in the hearts of the faithful. This Personality extension is called the Holy Spirit. The Spirit is not a third divine Person, but the very Persons of the Father and the Son. The Father and the Son share the same Spirit.
