The Trinity Doctrine is unbiblical

Alright, good luck to all. I really want to use these debates for fun as well as for the benefit of both debaters in learning and improving our knowledge of the subject at hand. I want to keep these statements brief and to the point. 1. Most Christians generally believe that the coming of Jesus Christ fulfills all the requirements from the Old Testament , to be the Messiah as well as "God with us". The problem that Christians fail to answer is one simple question, where in the Old Testament is it written that the Messiah will be God? If it was so CLEAR and obvious that when the Messiah comes he will be God, the why isn't it specifically explained by the OT prophets? One would think, for something that important, that God Himself would take on human form like Hercules, should have been at least mentioned once? This in itself should raise a huge question mark, there are many ways that modern Trinitarians twist the Jewish text into something that perhaps, maybe, helps their position a "little" bit , but nothing substantial nor concise. 2. God is very clear in His salvation plan. We have an entire Old Testament that was used for centuries, from this we know that there is a God, this God is all knowing and all powerful, we know not to murder, steal, commit adultery etc... But yet NO WHERE does God tell us in the OT, "By the way there's actually three of Me and if you really studied hard enough you would know that." The fact is, God did tell us who He is, He is ONE. Deut 6:4 Hear, O Israel: The LORD our God, the LORD is one. ONE does not mean "compound unity", there is no such usage in the Hebrew language. One means 1, as in 1 thing, not 3 things that make 1. ONE is a singular pronoun, there is no way to get around this grammatical fact. With this in mind, let us not forget that the one thing that differentiated the Hebrews from the other faiths is that they did not believe in multiple gods, God really was ONE to them and not 3 in a compound unity of ONE. This abuses normal human language. When someone says ONE they mean ONE, not THREE in ONE. From how I read scripture, I see God as ONE person, it was from HIM, through His utterance that His Word was begotten. This Word then became flesh in a man named Joshua (Jesus) son of Joseph, and through the power of God, was resurrected and now sits at the right hand of His Father. Not the, "one God in three persons, co-eternal, co-essential co-equal, eternal generation, dual natures God of the Trinity Doctrine, which was later added by pagan minded church Fathers, who used common Greek religious thought to describe how they saw Christ. Now on to the historical side... The Trinity Doctrine, how we know it today, did not complete in its full form until the ecumenical council in Constantinople (681) came to a decision on is Christ had 2 natures. Now let us use normal reason and logic... Why would such a clear and concise subject, that is specifically taught int he scriptures, have to be debated for over 700 years to finally be accepted as "right" and always taught from the beginning? There was no debate on whether or not Jesus was the Messiah, there was no debate on who the apostles were and their roles, there was no debate on whether or not Christ died and resurrected, there was no debate on whether or not He was the Son of God. Yet for over 700 YEARS, there was constant debate and bloodshed over whether or not Jesus was actually God Himself in the flesh. In conclusion, Jesus was God and acted as God, as God's representative, Jesus was the Word of God in flesh. This however does not make him equal nor the same as His Father. For this statement, I am now deemed a heretic by majority of Christendom, but I can't let church tradition get in the way of how I see the scriptures.
