Christ is God

First, I am a Trinitarian, which means that I think Christ is God. However, I am going to play devil's advocate in this debate by arguing that Christ is not God. May the Lord deal with me, be it ever so severely, if I win this debate.Since there are so many rounds in this debate, I'm going to try to keep my posts short. First, I'll respond to Pro's case, then I'll make a case of my own.Pro's casePro argues that because Christ is begotten of God, that he is therefore of the same nature as God and is therefore God. But assumes mistakenly that Christ is begotten of God literally in the same sense that humans beget humans. God did not concieve and give birth to Christ. The "begotten" language is metaphorical. It means the son is declared or considered to be the son of God. This phraseology comes from the Old Testament in which it is applied to kings of Israel. Psalm 2:6-7 “But as for me, I have installed my king upon Zion, my holy mountain. I will surely tell of the decree of the LORD: He said to me, ‘You are my son, today I have begotten you.’”Psalm 89:20-27 “I have found David my servant; with my holy oil I have anointed him….He will cry out to me, ‘You are my Father, my God, and the rock of my salvation.’ I also shall make him my firstborn, the highest of the kings of the earth.”2 Samuel 12:12-14 “When your [David’s] days are complete and you lie down with your fathers, I will raise up your descendant after you, who will come forth from you, and I will establish his kingdom. He shall build a house for my name, and I will establish the throne of his kingdom forever. I will be a father to him, and he will be a son to me; when he commits iniquity, I will correct him with the rod of men and the strokes of the sons of men.”Calling Jesus the "begotton son of God" is just another way of calling Jesus the messiah, i.e. the eschatological king of Israel. It doesn't imply that Jesus is God anymore that it implies David and Solomon are God.My caseI'm going to make two arguments against the deity of Christ.The indiscernibility of identiclesAccording ot the indiscernibility of identicals, if two entities are actually the same entity, then whatever is true of one must be true of the other, and vice versa. If there is anything true of one that is not true of the other, then it is impossible that they are the same entity.From this, it's quite easy to prove that Christ is not God. God is all knowing, which entails that God knows all true propositions. However, Mark 13:31-32 tells us that Christ does not know the day or the hour of the eschaton. So there is something true of God that is not true of Christ, and that means it's impossible for Christ to be God.Hebrews 1:3According to Hebrews 1:3, Christ is the exact representation of God's being. Now, according to the doctrine of the Trinity, Christ is a distinct person from the Father, but they share the same being since there's just one God. If Hebrews 1:3 said that Christ was the exact representation of God's person, then there wouldn't be a problem since Jesus could be considered the exact representation of the person of the Father. But instead, Hebrews 1:3 says Christ is the exact representation of God's being. If one thing is a representation of another, then there are two distinct things. That means Christ is a distinct being from God. He isn't merely a distinct person. Since there's only one God, and Christ is a distinct being from God, it follows that Christ is not God.
