The nature of God as revealed in Scripture centers on the truth that elohim, though consisting of more than one Personality, functions as a single institution united by agreement of mind, character, and purpose rather than by some mysterious commingling of essence. Within this family structure, government exists, and the Son submits to the Father, who is explicitly called greater. This establishes that the Supreme God—the Father—holds ultimate authority and responsibility, while the Son, though fully God, operates under the Father's direction, always doing what the Father assigns. This hierarchical order directly contradicts the Trinity doctrine's claim that the Father, Son, and Holy Spirit are "co-equal," since Jesus Himself declared, "My Father is greater than I," and Paul confirmed that "the head of Christ is God," showing inequality in authority even where there is equality in nature as beings of the God kind. The Trinity doctrine, by contrast, presents a closed Godhead admitting no additions, which forces its adherents to abandon the biblical teaching that redeemed humanity is destined to become part of the God family, or elohim, which is in the process of expanding. This doctrinal shift illustrates how altering a foundational truth about God's nature forces a cascade of changes throughout an entire system of belief, since biblical doctrines interlock like a puzzle. Central to defending the Father's supremacy is the demonstration that the Holy Spirit is not a third personality equal to the Father and Son, but rather the power emanating from the Father's mind, by which He accomplishes His will and extends His presence throughout creation. Numerous scriptures pairing the Father and Son in greetings, mediatorial roles, thrones, kingdoms, and inheritance consistently omit any mention of the Holy Spirit as a personality, revealing that only two Personalities exist within the God family. The Father's supremacy is further shown in that only one Mediator—the Son—stands between humanity and God, with no room made for another divine personality in that role. The Father's ability to be present everywhere, as expressed in passages about His Spirit filling all places, demonstrates that this Spirit is the means by which the one supreme Personality, the Father, extends His mind and power throughout His creation, not evidence of a separate coequal being. The historical witness confirms this understanding, since the Trinity doctrine did not appear until centuries after Christ and the apostles, introduced through councils influenced by political motivations rather than derived from clear scriptural statement. The biblical witness—including the total absence of any personal expression of the Holy Spirit's character, in contrast to the vivid personality repeatedly attributed to the Father and the Son—confirms that the Godhead consists of two distinct Personalities united in perfect agreement, with the Father standing supreme in authority over the Son, who in turn will ultimately subject Himself back to the Father so that God may be all in all. This structure preserves both the unity and the ultimate supremacy of the Father within the divine family, while maintaining the promised destiny of the redeemed to be incorporated into that same family as true sons and daughters of God.

The concept of the Supreme God centers on the Father, who is identified as the Absolute or Supreme God because He is that point beyond which there is nothing—no God to whom He must answer or submit. Herbert Armstrong used the term "Supreme God" while others preferred "Absolute God," but these are synonyms describing the same reality: the Father alone occupies the highest rank within the God kind, with no God beyond Him. This ranking does not diminish Jesus, who is equally God in nature—uncreated, eternal, spirit, worthy of worship—but who occupies a different function and responsibility within the family of God beings. Philippians 2:6 states Christ thought it not robbery to be equal with God, confirming equality of being, while numerous other passages (John 5:30, John 6:38-39, John 8:29, John 12:49-50, John 14:28, John 20:17, Revelation 3:12) show Jesus consistently submitting to the Father's will, calling the Father greater than Himself, and even referring to the Father as "my God" after His resurrection. This demonstrates that ranking within the God kind concerns authority and function, not qualitative superiority—just as a husband's headship over his wife does not make him qualitatively better, but reflects assigned role and responsibility. First Corinthians 11:3 establishes this hierarchical structure explicitly: the head of Christ is God. First Corinthians 8:6 and Ephesians 4:4-6 reinforce that there is "one God, the Father... who is above all," distinguished from "one Lord Jesus Christ." First Timothy 1:17 further identifies the Father alone as "the only wise God." Together these passages show that while the Godhead consists of two eternal, uncreated Beings sharing the same divine nature—the God kind—only the Father holds the position of ultimate authority. This distinction connects to the broader relationship between the Father and Son. Elohim, though plural, does not inherently mean "family," yet the term appropriately describes the Father and Son's relationship since Scripture reveals two Beings perfectly united in mind and purpose, functioning as Father and Son, with believers becoming Their spiritual children. Jesus' preexistence—as the Rock that followed Israel, the "I AM" who spoke to Moses, and the Word who was with God in the beginning—confirms His eternal, divine status alongside the Father, yet He remains the Son, carrying out the Father's will and revealing the Father to those called to know Him. Ultimately, this understanding calls believers to recognize their own place within God's hierarchical purpose, just as Jesus submits to the Father despite equal divine nature. Believers are to fulfill their assigned function without envying others' roles, since being "just as good as" someone else is not the issue with God—faithful submission to one's calling is. This mirrors the very submission Jesus Himself demonstrates toward the Father, the one Supreme, Absolute God, so that ultimately, as Paul writes, "God may be all in all."

The relationship between the Father and the Son centers on a crucial distinction: the Father alone is the Supreme God, also called Absolute Deity, while Jesus Christ, though fully of the God-kind, is His perfect Complement rather than His equal. This term, drawn from Colossians 2:9, means that Christ fills up, completes, and makes perfect the revelation of the Father to humanity—He is the visible, audible Image, Word, and Mediator through whom the invisible Father is known. Because Christ performs this role so completely, He might appear to human eyes as the Absolute Deity, but Scripture repeatedly distinguishes the two: the Father is greater than the Son, the Father sent the Son, and seeing the Son is equivalent to seeing the Father precisely because the Son is not the Father but His flawless counterpart. The Supreme God's uniqueness lies in the fact that He alone answers to no one; He has no God above Him, and His will is invincible and never yielded to another. By contrast, the Son has a God, appeals to Him for deliverance, and submits His will to the Father moment by moment. This is confirmed in Christ's own cry, "My God, My God, why have You forsaken Me?" and in His words to Mary Magdalene about ascending to "My God and your God." Paul's epistolary salutations reinforce this by consistently naming the Father as "the God and Father of our Lord Jesus Christ," establishing two distinct personalities rather than co-equal members of a Trinity. Though Jesus is rightly called divine—since divinity denotes direct relation to and origin from the Supreme God—this label is inadequate for Him. John the Baptist, though himself divine and judged by Jesus as the greatest man ever born, testified that Jesus ranks above him and existed before him, affirming Christ's pre-existence and superiority over every other being who might be called divine. Unlike the Father, who gives all things and needs nothing, the Son continually receives from and defers to the Father, declaring that He does nothing of Himself but seeks the Father's will. This submission was not merely a deathbed act but a lifelong pattern, even amid Christ's extraordinary gifts and constant testing by Satan. His statement "Not My will, but Yours be done" epitomizes His relationship to the Supreme God, and this submission is presented as the model believers must follow, since salvation and spiritual growth depend on our relationship with the Father, to whom Christ Himself reconciles us. Recognizing the Father as the sole Supreme God—the Source, Sender, and Sustainer of all things—while honoring the Son as His perfect Complement, dismantles the foundation of Trinitarian doctrine and establishes the true hierarchy through which humanity is invited into fellowship with God.
