32 For example, whoever speaks a word against the Son of man, it will be forgiven him, but whoever speaks against the holy spirit, it will not be forgiven him, no, not in this system of things nor in that to come (Matthew 12).
So the holy spirit and the Son are not co-equal and are different beings.
2
15 He said to them: You, though, who do you say I am?
16 In answer Simon Peter said: You are the Christ, the Son of the living God.
17 In response Jesus said to him: Happy you are, Simon, son of Jonah, because flesh and blood did not reveal [it] to you, but my Father who is in the heavens did (Matthew 16).
So God revealed it not Jesus, so they are two different spirits.
3
23 He said to them: You will indeed drink my cup, but this sitting down at my right hand and at my left is not mine to give, but it belongs to those for whom it has been prepared by my Father (Matthew 20).
So God and Jesus have separate possessions.
4
18 Jesus said to him: Why do you call me good? Nobody is good, except one, God (Mark 10).
So God is good and Jesus is not, so they are different people with different characters and different levels of righteousness.
536 Concerning that day and hour nobody knows, neither the angels of the heavens nor the Son, but only the Father (Matthew 24).
So God knows things that Jesus does not know. So they have no 'unity of Godhead'.
6
1 Do not let your hearts be troubled. Exercise faith in God. Exercise faith also in me (John 14).
Two different beings to put your faith in.
7
28 You heard that I said to you, I am going away and I am coming [back] to you. If you loved me, you would rejoice that I am going my way to the Father, because the Father is greater than I am (John 14).
So the two of them are not co-equal then.
8
42 saying: Father, if you wish, remove this cup from me. Nevertheless, let not my will, but yours take place (Luke 22).
So God and Jesus have two different wills. So there is no 'unity of Godhead'.

41 Therefore they took the stone away. Now Jesus raised his eyes heavenward and said: Father, I thank you that you have heard me.
42 True, I knew that you always hear me; but on account of the crowd standing around I spoke, in order that they might believe that you sent me forth (John 11).
So God sent Jesus forth, and God himself remained entirely in heaven whilst Jesus was on the earth.
10
9 You must pray, then, this way: Our Father in the heavens, let your name be sanctified (Matthew 6).
Jesus himself was entirely on earth and God was entirely in heaven when he said this!
11 (we were enjoying ourselves so much)!
46 About the 9th hour Jesus called out with a loud voice, saying: Eli, Eli, lama sabachthani? that is, My God, my God, why have you forsaken me? (Matthew 27).
One cannot easily forsake oneself can one! The Father was God of the son. The son was not God of the father. This was one of Sir Isaac Newton's anti trinity arguments.
As a final argument, if it is true that Jesus and God are the same person, then Jesus talked to himself in public, and prayed to himself in private and so was in fact a schizophrenic. This is plainly a false insult both to God and to his Son.
12 (and another thing...)
16 The one alone having immortality [aqanasian], dwelling in unapproachable light, whom no one of men has seen, nor is able to see (1 Timothy 6).
Literally aqanasian means 'without death'. So God has not died and will never die. Whereas of course Jesus has died. Therefore Jesus is not God - QED.
13 (why stop?)
5 So too the Christ did not glorify himself by becoming a high priest, but [was glorified by him] who spoke with reference to him: You are my son; I, today, I have become your father.
6 Just as he says also in another place: You are a priest forever according to the manner of Melchizedek.
7 In the days of his flesh [Christ] offered up supplications and also petitions to the One who was able to save him out of death, with strong outcries and tears, and he was favorably heard for his godly fear.
8 Although he was a Son, he learned obedience from the things he suffered;
9 and after he had been made perfect he became responsible for everlasting salvation to all those obeying him,
10 because he has been specifically called by God a high priest according to the manner of Melchizedek (Hebrews 5)
One cannot be a priest of oneself. Jesus must be a different person to God in order that he can be God's priest. Just as Melchizedek was a different person to God. God became Jesus' father again by saving him out of death, by resurrecting him.

23 But each one in his own rank: Christ the firstfruits, afterward those who belong to the Christ during his presence.
24 Next, the end, when he hands over the kingdom to his God and Father, when he has brought to nothing all government and all authority and power (1 Corinthians15).
How do you hand over something to yourself?
