Trinitarianism is true Christianity. Trinity-deniers are usually not. Those are antichrists. Don't listen to anyone who says "Christendom" is a false religion while claiming to be a Christian. The outward appearance of a Christian can be a disguise. Know them by how they attack Christianity.
If a person is sincere, and read Hebrews 1 carefully, they could see that Hebrews 1:8 is inaccurately rendered in the
King James Bible, while verse 9 tells the truth: "But unto the Son he saith, Thy throne, O God, is for ever and ever: a sceptre of righteousness is the sceptre of thy kingdom. Thou (Jesus Christ) hast loved righteousness, and hated iniquity; therefore God, even thy God (or "my God"), hath anointed thee with the oil of gladness above thy fellows", or as a modern English translation reads at Hebrews 1:8, 9: "But about the Son, he says: “God is your throne forever and ever, and the scepter of your Kingdom is the scepter of uprightness. You loved righteousness, and you hated lawlessness. That is why God, your God, anointed you with the oil of exultation more than your companions.”(
New World Translation)
How could Jesus be God and yet have a God or "your God" that "anointed you with the oil of exultation more than your companions" ? Now, consider Hebrews 1:2, 3 that says: "Now at the end of these days (or the Jewish system of things that ended in 70 C.E.) he has spoken to us by means of a Son (Jesus Christ, in which the word "Christ" [or Messiah] means "anointed one" or one anointed by God for a special work), whom
he appointed heir of all things, and through whom he made the systems of things. He is the
reflection of God’s glory and the
exact representation of his very being (or mirrors God's feelings on everything), and he sustains all things by the word of his power. And after he had made a purification for our sins, he
sat down at the right hand of the Majesty on high."(
New World Translation)
How could Jesus be God and yet have "sat down at the right hand of the Majesty on high" ? Does God sit at his own right hand ? The apostle Peter wrote: "Baptism, which corresponds to this, is also now saving you (not by the removing of the filth of the flesh, but by the request to God for a good conscience), through the resurrection of Jesus Christ.
He is at God’s right hand, for he went to heaven, and angels and authorities and powers were made subject to him."(1 Pet 3:21, 22)
How could Jesus be God and yet be sitting at God's right hand, so that "angels and authorities and powers were made subject to him" ? If Jesus is God, would angels and authorities and powers be made subject to him, since God has always had the angels as subject to him ?
At Hebrews 10:12, Paul says of Jesus Christ: "But this man offered one sacrifice for sins for all time and
sat down at the right hand of God". And at 1 Timothy 2, Paul wrote: "For there is one God, and one mediator
between God and men, a man, Christ Jesus, who gave himself a corresponding ransom for all."(1 Tim 2:5, 6)
Again, does God sit at his own right hand ? Those who are reasonable realize that God does not sit at his own right hand, but someone of lower rank that has his favor does. And how Jesus be God and yet be a mediator between God and men ?
And at Revelation 21:7, who is speaking ? Not Jesus, but God, whose name is Jehovah (see Isa 12:2,
KJV), for Revelation 21:5 says: "And the One seated on the throne said: “Look ! I am making all things new.” Remember, Jesus Christ is at Jehovah's right hand and is not sitting on the throne, so that at Revelation 21:7, it is Jehovah God that is speaking, saying: "Anyone conquering will inherit these things, and I will be his God and he will be my son."
And yes, at Isaiah 9:6, Jesus is called "Mighty God" or
El Gibbohr in Hebrew, but he is
not Almighty God or
El Shaddai in Hebrew (see Gen 17:1), for even the angels are "mighty in power".(Ps 103:20) And even the wicked judges of Israel were called "gods".(Ps 82:1, 2; see also John 10:34, 35)
And at John 20:28, Thomas said: "My Lord and my God", but does that mean that Jesus is God ? Had you carefully read what Jesus told Mary Magdalene upon his resurrection from the dead, that "Stop clinging to me, for I have not yet ascended to the Father. But go to my brothers and say to them, ‘I am ascending to
my Father and your Father and to
my God and your God", you could easily see that Jesus is
not God, but was ascending to "my God".(John 20:17)
And 2 Peter 1:1 does not say that Jesus is God, but rather that Peter addressed his letter "to those who have acquired a faith as precious as ours through the righteousness of our God and the Savior Jesus Christ", for had you carefully read Peter's first letter, it said at 1 Peter 1:3: "Praised be the God and Father of our Lord Jesus Christ", you could have seen that Jehovah God is Jesus Father (and all those who exercise faith in him).
Ditto for Titus 2:13, for had you read Titus 1:4, that says: "May you have undeserved kindness and peace from God the Father and Christ Jesus our Savior", whereby Paul makes a distinction between God and Jesus, you could have easily recognized that Jesus is not God.(Note: Titus 2:13 accurately reads: "while we wait for the happy hope and glorious manifestation of the great God and of our Savior, Jesus Christ")
And being called "rock" at 1 Corinthians 10:4 does
not make Jesus God, as for example Jehovah being called "Savior" at Isaiah 43:3, does not mean that someone else cannot be called "savior", for all the "judges" who saved Israel from their opposers were called "savior".(Judges 3:9; 15)
At Matthew 16:18, Peter is also called a "rock" or more accurately "a piece of the rock", for his name in Greek is
Petros and means just that, for Peter was given that name by Jesus (John 1:42), and in which Peter would be like a rock in support of the new Christian congregation that came into existence on Pentecost 33 C.E.(Acts 2), taking the lead in making known Jesus as the promised Messiah to the Jews.(Gal 2:7)
At Matthew 7:24, Jesus shows that the word "rock" means something firm on which a home can be built, so that Jesus also calls himself a "rock" at Matthew 16:18, using the Greek word
petra, on which the Christian congregation would be built, so that it could not be shaken from its foundation or torn apart.(see Hebrew 12:28)
