HarlyD, From your post.
All we know is that the Trinity is revealed to us in both the Old and New Testament. It is more complete in the New as this mystery has been (somewhat) revealed. John tells us that those who deny the eternal Father/Son relationship is evidence that they are unbelievers.
1Jn 2:21-26 I write to you, not because you do not know the truth, but because you know it, and because no lie is of the truth. W ho is the liar but he who denies that Jesus is the Christ?This is the antichrist, he who denies the Father and the Son. No one who denies the Son has the Father. Whoever confesses the Son has the Father also. Let what you heard from the beginning abide in you. If what you heard from the beginning abides in you, then you too will abide in the Son and in the Father. And this is the promise that he made to useternal life. I write these things to you about those who are trying to deceive you.
You underlined the wrong part, Zuriel has not denied the Father or the Son. I feel you have a much bigger problem in the preceding verse.
Who is the liar but he who denies that Jesus is the Christ?
Matthew 16:13-17King James Version (KJV)
13 When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am?
14 And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets.
15 He saith unto them, But whom say ye that I am?
16 And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
Jesus is stating only a non spirit filled man would say he is god. He made the same point, to some degree, when Thomas called him god. He told him, “Seeing me is why you believe.” In other words, your unbelief made you think only a god could come back to life. Notice also He did not tell Thomas the same thing He told the other disciples about forgiving sin and did not blow the Holy Spirit on him.
Are you going to be a liar and not call Jesus the Christ, the anointed one of God as He and the Father claim or a god as men claimed 300 plus years after His death and resurrection?
You seem to have a hard time understanding Zuriel, stating in John, Jesus claiming His Father did the miracles thru Him. Maybe Peter will make it plain enough for you to understand the concept.
Acts 2:22-26King James Version (KJV)
22 Ye men of Israel, hear these words; Jesus of Nazareth, a man approved of God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know:
May God our Father lead us to His truth? BVB
You also states that men called our Lord Jesus "God" 300 years after his death. This is incorrect. Our Lord Jesus equated Himself to God and the Jews knew it.
Joh 10:33 The Jews answered him, "It is not for a good work that we are going to stone you but for blasphemy, because you, being a man, make yourself God."
Christ also equated himself with God the Father:
Joh 14:89 Philip said to him, "Lord, show us the Father, and it is enough for us." Jesus said to him, "Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father. How can you say, 'Show us the Father'?
I understand how difficult it is to understand the Trinity. It is best never to think or speculate on the essence of God. It always leads to trouble as it has here. However, to deny any part of the Trinity is to go down a very slippery slope. God is one essence but manifest Himself in three ways; Father, Son, Spirit. For further scriptural study on this I would refer you to the Westminster Confession Of God and the Holy Trinity:
I. There is but one only,[1] living, and true God,[2] who is infinite in being and perfection,[3] a most pure spirit,[4] invisible,[5] without body, parts,[6] or passions;[7] immutable,[8] immense,[9] eternal,[10] incomprehensible,[11] almighty,[12] most wise,[13] most holy,[14] most free,[15] most absolute;[16] working all things according to the counsel of His own immutable and most righteous will,[17] for His own glory;[18] most loving,[19] gracious, merciful, long-suffering, abundant in goodness and truth, forgiving iniquity, transgression, and sin;[20] the rewarder of them that diligently seek Him;[21] and withal, most just, and terrible in His judgments,[22] hating all sin,[23] and who will by no means clear the guilty.[24]
II. God has all life,[25] glory,[26] goodness,[27] blessedness,[28] in and of Himself; and is alone in and unto Himself all-sufficient, not standing in need of any creatures which He has made,[29] nor deriving any glory from them,[30] but only manifesting His own glory in, by, unto, and upon them. He is the alone fountain of all being, of whom, through whom, and to whom are all things;[31] and has most sovereign dominion over them, to do by them, for them, or upon them whatsoever Himself pleases.[32] In His sight all things are open and manifest,[33] His knowledge is infinite, infallible, and independent upon the creature,[34] so as nothing is to Him contingent, or uncertain.[35] He is most holy in all His counsels, in all His works, and in all His commands.[36] To Him is due from angels and men, and every other creature, whatsoever worship, service, or obedience He is pleased to require of them.[37]
III. In the unity of the Godhead there be three Persons of one substance, power, and eternity: God the Father, God the Son, and God the Holy Ghost.[38] The Father is of none, neither begotten nor proceeding; the Son is eternally begotten of the Father; [39] the Holy Ghost eternally proceeding from the Father and the Son.
