John 14:
[sup]16[/sup] And I (Jesus) will pray (to) the Father, and He will give you another Helper,
that He may abide with you forever —
[sup]17[/sup] the Spirit of truth, whom the world cannot receive, because it neither sees Him
nor knows Him; but you know Him, for He dwells with you and will be in you.
[sup]18[/sup] I will not leave you orphans; I will come to you.
[sup]23[/sup] … and We (God) will come to him and make Our home with him.
[sup]26[/sup] But the Helper, the Holy Spirit, whom the Father will send in My name,
He will teach you all things, and bring to your remembrance all things that I said to you.
The Greek word here for ”another” is ”allos” meaning ”another of the same kind”.
You forgot to quote a few verses:
25 “These things I have spoken to you while abiding with you.
26 But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you.
27 Peace I leave with you; My peace I give to you; not as the world gives do I give to you. Do not let your heart be troubled, nor let it be fearful.
28 You heard that I said to you, ‘I go away, and I will come to you.’ If you loved Me, you would have rejoiced because
I go to the Father, for the Father is greater than I.
29 Now I have told you before it happens, so that when it happens, you may believe.
30 I will not speak much more with you, for the ruler of the world is coming, and he has nothing in Me;
31 but so that the world may know that
I love the Father,
I do exactly as the Father commanded Me. Get up, let us go from here.
Not a very good trinity passage afterall
The plurality within the one true God:
Genesis 1:26 (ESV)
[sup]26 [/sup]Then God said, “Let us make man in our image, after our likeness.
Most evangelical scholars understand now that in the verse quoted God speaks in the counsel of angels. This is also noted in the NIV Study Bible footnote.
So you don't have the answer. I do. You only offer speculation.
Matthew 28:19 (ESV)
[sup]19 [/sup]Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
The answer is, don't look for the trinity in the TaNaKh (abbreviated from the Hebrew names of the Torah, Prophets and Writings called OT in Christian bibles), it is not there.
