In the beginning was the Word, and the Word was with God, and the Word was God. John 1:1
The doctrine of the Trinity has parallel truths that are complementary, not contradictory. Three unique identities co-exist in one tri-unified Godhead in an equal relationship working distinctly as purposeful personal extensions in the co-creation of the universe, with earth and humankind and all creatures, sustaining potentiation of divine connections to humanity in a communicable (prayer-linked), pedagogical mindset (Spirit-linked): with prescribed laws (prophetically scripture-linked) in all realms psychologically, spiritually, familial in relation with our minds existentially in a created biologic, physic, atomic, and cosmic reality sustained by the highest laws in each energy field. 1
The Christian faith affirms that there is one and only one God, eternally existing while fully and simultaneously expressed in three Persons, the Father, the Son, and the Holy Spirit. Each member of the Godhead is equally God, each is eternally God, and each is fully God—not three gods but three Persons of the one Godhead. Each Person is equal in essence as each possesses eternally, simultaneously, and fully the identically same and undivided divine nature. Yet each is also an eternal and distinct personal expression of that one undivided divine nature. Because of this, what distinguishes each Person of the Godhead from each other Person is not and cannot be the divine nature, since the identically same one and undivided divine nature is the full and eternal possession of the Father, and of the Son, and of the Holy Spirit. So, what distinguishes each Person of the Godhead from each other Person are the relationships that each has with each of the other Persons and his particular roles in relation to the others. In light of both the equality of essence yet differentiation of relationships and roles that exist among the Persons of the Godhead, we consider just how the church came to affirm these truths about the Trinity and how those Trinitarian relationships and roles are expressed within the Trinity of Persons. 2
The bible teaches that the Father is God. Yet it was evident that while on earth as our saviour and representative man, Jesus honoured prayed to and obeyed his Father.
The Doctrine of the Trinity Glorifies Jesus Christ
In 1 Corinthians 8:6 we can see that Jesus was active in creation: yet for us there is but one God, the Father, from whom are all things and we exist for Him; and one Lord, Jesus Christ, by whom are all things, and we exist through Him.
The triadic relationship of God can be seen into whom Christians are baptized. Matthew 28:19-20 states: Go ye therefore, and make disciples of all the nations, baptizing them into the name of the Father and of the Son and of the Holy Spirit: teaching them to observe all things whatsoever I commanded you: and lo, I am with you always, even unto the end of the world.
Further, we are called to know the true God in the context of Jesus Christ, whom the Father sent. John 17: 3: And this is eternal life, that they know you, the only true God, and Jesus Christ whom you have sent.
In 2 Corinthians 13:14: the Hoy Spirit is noted in the triad: May the grace of the Lord Jesus Christ, the love of God, and the fellowship of the Holy Spirit be with you all.
The Supremacy of Jesus in the creation of all life is noted in Colossians 1:15-20 NLT: Christ is the visible image of the invisible God. He existed before anything was created and is supreme over all creation, for through him, God created everything in the heavenly realms and on earth. He made the things we can see and the things we can’t see—such as thrones, kingdoms, rulers, and authorities in the unseen world. Everything was created through him and for him. He existed before anything else, and he holds all creation together. Christ is also the head of the church, which is his body. He is the beginning, supreme over all who rise from the dead. So he is first in everything. For God in all his fullness was pleased to live in Christ, and through him God reconciled everything to himself. He made peace with everything in heaven and on earth by means of Christ’s blood on the cross.
