Ohhhhhh man............ I didn't want to jump in the middle of this battle, but I feel the need to point this out.

Forgive me BT.
Sure he knew that Jesus was God at that point in his life, but did he know that the Holy Spirit was also God. I doubt it, I didn't at that age. Simply asking if he believed that Jesus was God doesn't cut it by your own definition, that is duality of God, not trinity. I think it is common, especially among us who were saved and Baptised in our early teens, to come to a complete understanding of God's triune nature a little later in life. Especially the role of the Holy Spirit in that trinity.
That is my experience at least.
No problem brother.
If we look all the back to the beginning of the thread this was the initial question..
"
Why is a correct view of the doctrine of the Trinity important? And, can one be a true Christian and deny the doctrine of the Trinity? "
So we weren't talking about salvation per-say. But the importance of understanding the person of God. When we talk about salvation, we have to be very careful. After all the Bible tells us that the "requirements" for salvation are quite simple:
KJV said:
Romans 10:9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
But we move past this with the OP. We start talking about God. So according to Romans 10:9 we don't have to know about the trinity to be saved. While at the same time we can talk about certain cults that are around who teach that Jesus was a man, or that Jesus was a god amongst many gods. If a cultist is the one "witnessing" to you, and he/she is witnessing about a "Jesus" who is not the one found in the Bible. Then is the person who believes in this "Jesus" saved? I would say no according to the words of Christ:
KJV said:
Matthew 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Matthew 24:25 Behold, I have told you before.
Matthew 24:26 Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not.
False Christs (such as the christ of the Mormons and the christ of the JW's) will not save anyone because there is no salvation in them. So if we go back to the second part of the OP "can you be saved and deny the doctrine of the Trinity" you see why I say no.
Then we digressed with theseed who changed the question to:
BT, why does salvation depend on having correct theology? Why does one have know exactly what The Bible teaches to be a Christian--to be saved?
And the question was answered. Salvation depends on having a correct understanding of who Christ is, what He did, why He did it (this is called correct theology, a correct understanding). Why does one have to know exactly what the Bible teaches to be a Christian- to be saved? Well because the Bible is God's revelation to us. It is the Bible that teaches us how to be a Christian - to be saved.
From there the conversation digressed in the normal fashion between he and I, and for that I apologize.
In reading this comment by Nicodemus I realized (again) the idiocy of entering into circular debates with our good friend theseed. A mistake I have made before and will try to avoid in the future.
So to end this nightmare circle I'll finish (my posts) saying. That there is only one God, who sent His Son to save us all (John 3:16). If you believe on Him you will be saved (Acts 16:31). The salvation offerred to all men by God is a simple plan that we foolishly complicate.
Remember the "High Priests" of our day have traded in the breast-plates and the hems (Matthew 23:5) for caps and gowns. They do not seek to be called "Rabbi rabbi" (Matthew 23:7) rather they seek to be called "Doctor Doctor". (Of course this does not refer to all..)
