The belief that there is a Holy Trinity, that encompasses God, Jesus and the Holy Spirit as one single being is NOT in the Bible. This is a false teaching.
Read John in any version you wish ( I use the King James Version). Through out John Jesus himself repeatedly describes himself as the SON of God, as NOT God, and that God uses the Holy Spirit. He states he is NOT God, but rather his Son. That everything he does he does because his father lets him do it. He says it in NUMEROUS passages in John, in his own words.
What, then, is our doctrine? The Lord, in delivering the saving Faith to those who become disciples of the word, joins with the Father and the Son the Holy Spirit also; and we affirm that the union of that which has once been joined is continual; for it is not joined in one thing, and separated in others. But the power of the Spirit, being included with the Father and the Son in the life-giving power, by which our nature is transferred from the corruptible life to immortality, and in many other cases also, as in the conception of "Good," and "Holy," and "Eternal," "Wise," "Righteous," "Chief," "Mighty," and in fact everywhere, has an inseparable association with them in all the attributes ascribed in a sense of special excellence. And so we consider that it is right to think that that which is joined to the Father and the Son in such sublime and exalted conceptions is not separated from them in any. For we do not know of any differences by way of superiority and inferiority in attributes which express our conceptions of the Divine nature, so that we should suppose it an act of piety (while allowing to the Spirit community in the inferior attributes) to judge Him unworthy of those more exalted. For all the Divine attributes, whether named or conceived, are of like rank one with another, in that they are not distinguishable in respect of the signification of their subject. For the appellation of "the Good" does not lead our minds to one subject, and that of "the Wise," or "the Mighty," or "the Righteous" to another, but the thing to which all the attributes point is one; and, if you speak of God, you signify the same Whom you understood by the other attributes. If then all the attributes ascribed to the Divine nature are of equal force as regards their designation of the subject, leading our minds to the same subject in various aspects, what reason is there that one, while allowing to the Spirit community with the Father and the Son in the other attributes, should exclude Him from the Godhead alone? It is absolutely necessary either to allow to Him community in this also, or not to admit His community in the others. For if He is worthy in the case of those attributes, He is surely not less worthy in this. But if He is "less," according to their phrase , so that He is excluded from community with the Father and the Son in the attribute of Godhead, neither is He worthy to share in any other of the attributes which belong to God.
