Bowman, you're just reading your theology into the text. None of those verses explicitly state Yahweh is a triune God and none of them explain the relationship between Father, Son, and Holy Spirit. The "consubstantiation" idea didn't develop until the 3rd or 4th century. The "trinity" was clearly an idea that developed over time.
So no dice.
The concept of the "Trinity" took several hundred years to fully develop and so was not added by any single person in particular.
The three "persons" who make up the modern orthodox Christian version of the Trinity (there are still branches of Christianity which don't accept the orthodox formulation) are all mentioned in some way in the New Testament. What was bitterly disputed for centuries was whether they were connected as a Godhead at all and, if so, how. There were early forms of Christianity which wholly rejected the idea that Jesus was God at all and insisted on a more traditionally Jewish conception of the Messiah as simply a man ordained and anointed by God or perhaps as a heavenly or angelic being sent by God in human form. This form of Christianity, preached by the Ebionites, Nazoraeans and some others survived into at least the Fourth Century. Some were reverting to a more Jewish conception of the Messiah but it is believed by many modern scholars that the Ebionities' claim to be descended from relatives of Jesus and therefore to be the
original form of the Jesus sect has merit.
By the Second Century, however, the idea that Jesus was in some sense divine had well and truly taken hold in gentile Christianity. The main disupute then became in what sense he was divine. Adoptionists believed that Jesus was divine but that he only became so at his baptism. So they accepted that he is God but believed that he was not always so and that he was therefore not fully equal with God. The fact that the Gospel of Mark indicates Jesus' baptism as the point where he became the Messiah and that several passages in Paul's epistles indicate Paul believed Jesus
became God's anointed at his resurrection gave the proponents of this view some scriptural basis.
Over the next two centuries various forms of Modalism developed, arguing that God could only ever be one and so the Father, the Son and the Holy Spirit could only be "aspects" or "masks" of the unity that is God as perceived by the observer/believer and not separate beings in any sense. Then there was Arianism, which accepted that the Son was divine but "proceeded from the Father" and so was not eternal and co-equal with him.
The poor relation in all versions of the Trinity and debates about it is the "Holy Spirit". In Judaism, the רוח הקודש or "ruach ha-kodesh" was the divine property of prophecy and wisdom and therefore the active element of Yahweh in the world. It's in this purely Jewish sense that most of the references to this "holy spirit" of Yahweh in the New Testament are meant - 2Corinthians 13:14 only looks like a Trinitarian formula now, no Jew of Paul's time would have interpreted it that way at all or would have even dreamed of doing so (ditto for Matt 28:19). Once Christianity drifted from its Jewish roots, however, the subtle distinction between an active aspect of God in the world and another form and then eventual a "person" of God quickly became blurry and was lost altogether.
By the Second Century the idea that there was, in some sense, a Trinity was dominant and other conceptions of Christianity were being marginalised and dismissed as "heresies". But there still followed several centuries of struggle over which of the competing conceptions of this Trinity was "correct". After Constantine legalised Christianity in 312 AD he was not pleased that his new faith was riven with divisions and called the Council of Nicea to settle the disputes over the nature of the Trinity. The Orthodox view won out over its then main rival, Arianism. But Arianism then got the support of several of Constantine's successors and staged a comeback. Even after Ariansim was finally marginalised, non-Arian Christianity was then divided again, this time over the question of whether Jesus had one divine nature (Monophysitism) or a human and divine nature at the same time (the Chalcedonian position). Disputes over this and similar variations on Trinitiarian doctrines continued for centuries and often resulted in schisms and, occasionally, persecutions.
What is perfectly clear is that the whole idea of a Trinity evolved over centuries and what has emerged as the "orthodox" position held by most Christian churches today did so more as a result of luck, violent debate, Imperial power and occiasionally violence, conflict and torture. Claims made by modern conservative Christians that the orthodox position is somehow "clearly" the right one are undermined by this history of conflict and violence - it it was so "clear" there would not have been this whelter of disputes and conflicting positions.

I'd say the reason the whole concept has such a history of conflict and dispute and is so theologically incoherent is that it evolved out of a jumble of inconsistent ideas and traditions to begin with. It seems incoherent because it is.
