P73:5, 6:1.1 The Eternal Son is the original and only-begotten Son of God. He is God the Son, the Second Person of Deity and the associate creator of all things. As the Father is the First Great Source and Center, so the Eternal Son is the Second Great Source and Center.
P74:1, 6:1.2 The Eternal Son is the spiritual center and the divine administrator of the spiritual government of the universe of universes. The Universal Father is first a creator and then a controller; the Eternal Son is first a cocreator and then a spiritual administrator. "God is spirit," and the Son is a personal revelation of that spirit. The First Source and Center is the Volitional Absolute; the Second Source and Center is the Personality Absolute.
P74:2, 6:1.3 The Universal Father never personally functions as a creator except in conjunction with the Son or with the co-ordinate action of the Son. Had the New Testament writer referred to the Eternal Son, he would have uttered the truth when he wrote: "In the beginning was the Word, and the Word was with God, and the Word was God. All things were made by him, and without him was not anything made that was made."
P74:3, 6:1.4 When a Son of the Eternal Son appeared on Urantia, those who fraternized with this divine being in human form alluded to him as "He who was from the beginning, whom we have heard, whom we have seen with our eyes, whom we have looked upon, and our hands have handled, even the Word of life." And this bestowal Son came forth from the Father just as truly as did the Original Son, as is suggested in one of his earthly prayers: "And now, O my Father, glorify me with your own self, with the glory which I had with you before this world was."
P74:4, 6:1.5 The Eternal Son is known by different names in various universes. In the central universe he is known as the Co-ordinate Source, the Cocreator, and the Associate Absolute. On Uversa, the headquarters of the superuniverse, we designate the Son as the Co-ordinate Spirit Center and as the Eternal Spirit Administrator. On Salvington, the headquarters of your local universe, this Son is of record as the Second Eternal Source and Center. The Melchizedeks speak of him as the Son of Sons. On your world, but not in your system of inhabited spheres, this Original Son has been confused with a co-ordinate Creator Son, Michael of Nebadon, who bestowed himself upon the mortal races of Urantia.
P74:5, 6:1.6 Although any of the Paradise Sons may fittingly be called Sons of God, we are in the habit of reserving the designation "the Eternal Son" for this Original Son, the Second Source and Center, cocreator with the Universal Father of the central universe of power and perfection and cocreator of all other divine Sons who spring from the infinite Deities.
