Prologue.
After tireless nights, I have auspiciously studied so fruitfully, and my dispositions are optimistic, as I have studied without divine revelations, as I am NOT a prophet, nor patriarch, nor preacher, nor holy-man, and yet I have studied with great endurance to conclude in the perceptible nature of God, but there is the equal propensity for being erroneous, as there is with accuracy, and I am fallible as all humans are.
On The Trinity.
To clarify the nature of God. God is an eternal, uncreated, perfect, infallible, omnipresent, omnipotent, and omniscient being. His nature is not divisible, and thus, if God had attempted to create another iteration of Himself, he would have only created Himself, though this creation would not be distinct, as it would share God's nature, mind, and essence due to these facets. God is of a superior criteria to Men, and God is above all Men. The Trinity exists as His divine emanations, representing Agape, Apeiro, and Logos. The Reason and the Word is closest to the earthly realm, though remains disparite, and has walked the earth as the Logos, Kg. Jesus Christ, whom walked among the people of Israel in a human body, though possessed a fully divine essence and mind, due to His criteria of the Word and the Reason, the Logos. Kg. Christ had dwelt devoid of transgression he had inflicted upon others, and bore the transgressions imposed upon Him, and yet he invoked the One, Apeiro, who is the light at the center of the universe. Kg. Christ is evident in his Christophanies, in which He had appeared, and spoken as God, and had spoken to Abraham. The Angel of the Lord is Logos, and existed prior to Abraham, and prior to the universe, as the Logos is an eternal emanation. The Trinity itself is merely the simplified nature that the One, God, presents to us, and His true nature is entirely unknowable and cosmicist, as are His intentions, which are supreme and incomprehensible, and devoid of repudiation or abrogation. Christianity is very strictly monotheistic, but this is because of the manner in which God is defined. Because to be a God, and not essentially a superhuman, a being must be perfect in every way, omniscient, omnipotent, omnipresent, and omnibenevolent, and by this definition, there can only be one God, so "could God create a god?" is answered by the fact "he could certainly try, but it would just be Him, because God's definition is exclusive. This isn't to say there is a system above God, like in Mormonism, rather, that this is God's nature, which is inseperable from God." This logically entails that God is one, and very strictly so. This is observed by Augustine, and Aquinas. For this reason, God may be expressed in multiple persons, like the Lamb/Logos/Christ, which is necessary for the salvation of man, who is fallen, per Genesis, and per the coming Son of Man, or the lamb the Angel of the Lord promised to Abraham for all of humanity, which would come in the person of Jesus Christ, who is man's savior, and who is God, as well as fulfilling the Mosaic Law, and strengthening the moral law.
