But again, whether the doctrine of holy trinity is in the bible is debatable,
Sure, but like much else, it's the view of God that best takes into account the whole revelation. It sure isn't tritheism or polytheism; Modalism makes no sense; Arianism ignores or misinterprets much; it can't be that an angel came in human flesh and then returned to being an angel after ascending.
but the identity group of "trinitarians" is nowhere to be found in the bible. I'm vehemently against the notion of "no one comes to the Father except through the trinitarian doctrine", because that's a twisting of God's words. A thread with a title of "trinitarian vs non-trinitarian" is wrong at the beginning when it artificially divides God's people into two camps, and everybody including you just goes along with that and defends that, only I call it out.
But, you're once again begging the question. The entire point is, can a person
not believe in the Trinity, or at the least deny the deity of Jesus,
and be considered one of "God's people"?
You can bet that all those religious elites, the Pharisees, Sadducees, scribes and lawyers knew the Scripture better than anybody else, they'd devoted their whole life studying the Torah, they can recite any passage from the top of their head, and yet none of them knew God, they ended up crucifying God on the cross. You can say that they were reading the Old Testament, we're living in the New Testament era, then how come that false prophets are rising in Jesus's name and many are deceived? (Matt. 24:4-5) What prompts you to ask me repeatedly - "which Jesus"?
Because you are continually begging the question by saying things such as "The whole bible is about . . . Jesus who IS truth," "I identify myself as a child of God, my doctrines, my church or my pastor didn’t die to atone my sins, Christ did," and the "God of salvation is relevant to everyone."
Mormons claim to believe in the biblical Christ, but he is one of many and the literal brother of Satan and many others. JWs claim to believe in the biblical Christ, but he is the incarnate archangel Michael, who (possibly) then returned to being an angel after he ascended. Arians claim to believe in the biblical Christ, but he is nothing more than a man, a mere creature. Tritheists claim to believe in the biblical Christ, but he is one of three Gods, in contradiction to biblical monotheism. Trinitarians claim to believe in the biblical Christ, but he is one of three eternal, divine persons, the Son of God who came and took on human flesh, being
both truly human and truly God.
That is five irreconcilably different "biblical" Christs. None could be true, but it is not possible that more than one could be true. I don't see how we can just believe Jesus to be whomever or whatever we want him to be and be saved.
That is why I keep asking "Which Jesus?". I stated previously that "Either God is Unitarian or Trinitarian (or something else), but he
cannot be both (or all) of those. To get that wrong is to believe in another god." It is the same with Jesus. I even gave a verse where Paul implies it is possible to believe in "another Jesus," along with "another spirit" and "another gospel" (2 Cor 11:4). In Gal 1 he says that anyone who proclaims a different gospel is to be considered accursed. Jesus said that salvation is through believing in his name (John 3:18), which is why John repeats that at the beginning and end of his gospel (John 1:12; 20:31). To believe in [on] the name of Jesus is to believe in "the sum of the qualities which mark the nature or character of a person. To believe in the name of Jesus Christ the Son of God, is to accept as true the revelation contained in that title" (M. R. Vincent, Word Studies in the New Testament).
Also, by saying things such as "and yet none of them knew God, they ended up crucifying God on the cross" and "false prophets are rising in Jesus's name and many are deceived," you once again completely undermine your complaint against both the use of "Trinitarianism vs non-Trinitarianism" and the debate of which position is true (or most likely to be true), and show exactly why coming to the truth of who Jesus is, who he claimed to be, is of central importance. You say they crucified "God on the cross," but that isn't what at least two others in this discussion believe, and they think they believe Scripture. And, don't false prophets rise in the name of a false Jesus?
Look at what Jesus says:
Mat 24:5 For many will come in my name, saying, ‘I am the Christ,’ and they will lead many astray. (ESV)
Is that not exactly what this debate is about? Even if it isn't a particular person claiming to be Christ, although that happens all the time, it is about others claiming to follow a Christ who is "another Jesus," thus they are led astray. Who Jesus is is central to his work and central to the gospel and central to salvation.
