The God of the Bible is not triune in nature.

As round 2 is only for opening arguments, I won't give rebuttals till the next round. Here is my opening argument: The Scriptures proclaim that there is one, and ONLY ONE God in all of existence. (Deu 4:35; Isa 43:10-11; 44:6, 8; 45:5-6, 14, 21-22; 46:9; Mal 2:10; Rom 3:30; 1 Cor 8:6; Eph 4:6; Jam 2:19) It also says that there is only one true God. (John 17:3; 1 John 5:20) This means that all other gods are false. Since there is only one God, then no other being can truly be a god. This is why they are false gods [that is, not truly gods]. Now, Scripture plainly identifies the Son as God in John 20:28. The term "my God" refers to the true God every single time it is used in the Bible outside of John 20:28, establishing the consistent linguistic use of the term. Thomas here calls Jesus in the Greek, ho kurious mou kai ho theos mou, literally, the Lord OF me and the God OF me. So John 20:28 calls Jesus the God OF Thomas, and in verse 29 Jesus approves. Now since there is only one true God, either Jesus was the true God in John 20:28, or a false god. Which is it? I look forward to my opponents answer. But Jesus is also identified as God in Isaiah 9:6. So which is it: is he a true god, or a false god? If he is a true god, then he must be the Almighty, for there is only one true God, not two; if he is a false god, we are not saved, for no pretender could save us. He can't be another god besides the true God, because Scripture says there is ONLY ONE God. Isa 44:24 tells us that Yahweh made all things, stretched out the heavens ALONE, spread out the earth BY HIMSELF; yet Scripture reveals the Father as creator (Isa 64:8), and the Son (Col 1:16-17; Heb 1:2, 8-10), and the Holy Spirit (Ps 104:30; Job 26:13; 33:4) Combine this with the plural pronouns "us" and "our" in Genesis 1:16 and the trinitarian has an airtight case. If Jesus and the Holy Spirit are not one God with the Father, then God the Father had help and did not create all things alone, by himself, as he said in Isaiah 44:24. If the trinity is true, harmony comes to the texts. At Isaiah 43:11 Yahweh declares, "I myself am Yahweh and BESIDES ME THERE IS NO SAVIOR." (WEB) Scripture tells us plainly that Jesus is the Savior. (Matt 1:21; Lu 2:11; Acts 4:12; 2 Tim 1:10; Tit 1:4; 2 Pet 1:11, etc) So is Jesus Yahweh himself, or is he ANOTHER Savior BESIDES Yahweh? Which is it? If he is Yahweh, then he must be one Yahweh with the Father. For there is only one Yahweh. (Deu 6:4) If he is not Yahweh, then he is another Savior besides Yahweh, and Yahweh was lying when he claimed to be the only Savior. Which is it? Acts 4:12 says of Jesus, that "there is no salvation in anyone else." Now, if Jesus is not God, then there can be no salvation in God, for there is no salvation in anyone else but Jesus. The fact that Jesus receives prayer proves he is God. John 14:14 says in the New American Standard Bible: "If you ask Me anything in My name, I will do it." Not only does Jesus encourage believers to pray to Him by saying, "ask Me anything," but He is the One who answers the prayer when He promises, "I will do it." While this Scripture is a strong support of prayer being rendered to Jesus, it is complicated by the fact that some translations omits the "me" in the phrase "ask Me anything" in John 14:14. But the Greek text itself states: "If ever anything you should ask me in the name of me this I shall do." The Kingdom Interlinear also has "ASK ME" in the Greek. The reason that certain Bible versions leave out the "me" is due to a textual variant in the manuscripts of the Greek text of this verse. The Majority text (most dating from around the 9th century) split on this issue with some containing the "me" and others dropping the "me." But in recent years, scholars have uncovered manuscripts of the New Testament that date as far back as the second and third centuries. The oldest manuscripts we have available today of this verse in the Gospel of John are Papyrus 66, written in 125 A.D., and Papyrus 75, written sometime between 175-225 A.D. Both of these papyrus fragments contain the "me" in this passage. Not only do the oldest fragments of John that we possess today contain the "me," but two of the oldest ancient complete copies of the entire Bible in Greek, the Codex Sinaiticus and Codex Vaticanus written around the 4th century, both agree with the papyrus' renderings of "ask me" in John 14:14. Since Desiderius Erasmus complied and published the Greek text (Textus Receptus) of the King James Bible version in the 1500's, he did not have access to the older Greek manuscripts that we have today. Thus, the King James Bible version and other Bible versions based upon the Textus Receptus or the Majority text do not contain the "me" in John 14:14. Indeed, John 14:14 is a strong testimony to Jesus' approval of the early Christian practice of directing their prayers to Jesus Christ. Does not prayer only belong to God? 2 Corinthians 12:8-9 "In this behalf I three times entreated the Lord that it might depart from me; and yet he really said to me: "My undeserved kindness is sufficient for you; for [my] power is being made perfect in weakness.' Most gladly, therefore, will I rather boast as respects my weaknesses, that the power of the Christ may like a tent remain over me." Here Paul prayed to the "Lord" Jesus three times and Jesus answered his prayer by saying: "My... power is being make perfect in weakness." Paul concluded by admitting that he would "rather boast ...that the power of (who?) the Christ may like a tent remain over me." So, here again, we see an example of a Christian in the Bible praying to the Lord Jesus with Jesus responding to the prayer with His "underserved kindness" and "power." (NWT) We are told about Jesus hearing our prayers again in 1 John 5:12-16 and Acts 7:59. This would not be so if Jesus were not God. I must at this point mention the Granville Sharp rule of Greek grammar. This rule states that when there are 2 nouns that are both singular which describe a person, and these nouns are connected by the word "and," the first noun having the article, the second noun not having the article then they refer to the SAME PERSON. (*Note that the nouns cannot be personal names*) There is absolutely no exception to this rule in all of the Greek New Testament. Having stated this rule I find it necessary to present two verses of scripture that unequivocally qualify Jesus as both God and Savior. Titus 2:13 - while we wait for the blessed hope"the glorious appearing of our great God and Savior, Jesus Christ, (NIV) 2Peter 1:1 - Simon Peter, a servant and apostle of Jesus Christ, To those who through the righteousness of our God and Savior Jesus Christ have received a faith as precious as ours: (NIV) Notice in both verses the noun "God" (theou) has the article (tou) and is connected to the second noun "Savior" (soteros) which does not have an article, by the word "and" (kai). Thus "God and Savior" both refer to the Person of Jesus. Grammatically this is irrefutable. So not only is Jesus Savior, He is God! So I think I have made a good case that Jesus is definitely God, and since there is only one God, then the Father and the Son must be one God. Now, onto the Holy Spirit. That the Holy Spirit is God and Lord is clearly stated in the Scriptures. (Acts 5:3-4; 2 Cor 3:17) The Holy Spirit has the same attributes of Deity as the Father and the Son: The Father is eternal (Ps 90:2), and the Son (Isa 9:6; Mic 5:2), and the Holy Spirit (Heb 9:14) The Father is omniscient (1 John 3:20), and the Son (John 16:30; 21:17), and the Holy Spirit (1 Cor 2:10-11) The Father is omnipresent (1 Kings 8:27; Ps 137:8-18), and the Son (Matt 18:20), and the Holy Spirit. (Ps 137:7) The Father is omnipotent (Dan 4:35), and the Son (Matt 28:18; John 17:10), and the Holy Spirit (Isaiah 40:12-15) Definitions: Trinity: a tripersonal being (one being with three distinct minds) God: the divine nature, namely, omnipotence, omniscience, omnipresence, all-loving, etc. God: definition 2: any person who possesses divine nature. [Illustration: a scoop of flour is not the whole bag of flour, just as God the Son is not the entire Trinity, and yet, the scoop of flour is by nature flour, just like the whole bag of flour, and so to, God the Son is still by nature God, just like the entire trinity. He is part of the being that has that nature] Isaiah 46:9 says there is no one like God, but Jesus is so much like Him that if you see Him you see the Father. (John 14:9) Jesus was worshiped even though worship only belongs to God. (Heb 1:6; Matt 2:11; 8:2; 9:18; 15:25; 28:9, 17; John 9:38) The difference between God and his creation is the difference between the finite and the infinite. How could a man of finite qualities ever get so close to being like a God who has those attributes to an INFINITE degree? That's not possible. He had to be God to be that much like the Father. Isaiah 40:3 speaks about preparing the way for the LORD (Yahweh). When we compare this verse with Mark 1:3 we see that Jesus is the LORD who had the way prepared for him by John the Baptist. In Joel 2:32 it says that whoever calls upon the Name of the LORD (Yahweh) will be saved. This verse is quoted by Peter in Acts 2:21, and by Paul in Romans 10:13. Both apostles are clearly referring to Jesus as the LORD. In Isaiah 6:1-10 we read about the marvelous vision that Isaiah had revealing the glory of the LORD (Yahweh). John tells us in John 12:40-41 that this vision revealed the glory of Jesus. The New World Translation has reference in the margin of John 12 pointing to Isaiah 6. In Isaiah 44:6, the LORD (Yahweh) refers to himself as "the First and the Last". In Revelation 1:8 and 17, Jesus similarly refers to himself as "the Alpha and the Omega" and "the First and the Last". Also, creatures in heaven worship the Lamb and the Father in Revelation 5:13-14.
