Belief in the Old Testament precludes belief in the New Testament or Koran

I, myself, am an atheist, so I think it'll be interesting to play this side of the fence for once. Before starting, I'd like to make a clarification. That the New Testament may be incompatible with the Old Testament does not, itself, preclude belief in both, as people may hold contradictory beliefs. I will be addressing the proofs presented by pro and the alleged inconsistencies and incompatibilities and eschewing the topic of whether this, itself, precludes belief in them. Proof #1 - RebuttalThe population of the Israelites notwithstanding, the verses cited by Pro clearly indicate that the Lord did not speak to the entire Jewish nation. Rather he spoke to Moses, and Moses acted as a go-between. The verses that illustrate this point are: Then Moses went up to God, and the LORD called to him from the mountain and said, “This is what you are to say to the descendants of Jacob and what you are to tell the people of Israel - Exodus 19:3So Moses went back and summoned the elders of the people and set before them all the words the LORD had commanded him to speak. The people all responded together, “We will do everything the LORD has said. ” So Moses brought their answer back to the LORD. - Exodus 19:7 & 8 The LORD descended to the top of Mount Sinai and called Moses to the top of the mountain. So Moses went up and the LORD said to him, “Go down and warn the people so they do not force their way through to see the LORD and many of them perish. Even the priests, who approach the LORD, must consecrate themselves, or the LORD will break out against them. ” Moses said to the LORD, “The people cannot come up Mount Sinai, because you yourself warned us, ‘Put limits around the mountain and set it apart as holy. ’” - Exodus The LORD replied, “Go down and bring Aaron up with you. But the priests and the people must not force their way through to come up to the LORD, or he will break out against them. ” - Exodus 19:20-24 When the people saw the thunder and lightning and heard the trumpet and saw the mountain in smoke, they trembled with fear. They stayed at a distance and said to Moses, “Speak to us yourself and we will listen. But do not have God speak to us or we will die. ” - Exodus 20:18 & 19 Now, there are verses that seamingly imply that God did speak directly with the people: The LORD said to Moses, “I am going to come to you in a dense cloud, so that the people will hear me speaking with you and will always put their trust in you. ” - Exodus 19:9 On the morning of the third day there was thunder and lightning, with a thick cloud over the mountain, and a very loud trumpet blast. Everyone in the camp trembled. Then Moses led the people out of the camp to meet with God, and they stood at the foot of the mountain. Mount Sinai was covered with smoke, because the LORD descended on it in fire. The smoke billowed up from it like smoke from a furnace, and the whole mountainrembled violently. s the sound of the trumpet grew louder and louder, Moses spoke and the voice of God answered him. - Exodus 19:16-19 The LORD spoke to you face to face out of the fire on the mountain. - Deuteronomy 5:4 However, the context of these verses indicate that we should not interpret this as literally as it may seem. In the first verse, God did not speak in words. Rather the noises of the storm, and the trumpet blast, were interprted as the voice of God. Indeed, though it is said that the "voice of God answered" Moses, there is no indication of what he said. Furthermore, an addendum to the second verse is Moses acknowledging that the people were afraid to approach God, making it necessary for Moses to intervene. In all of the verses, the only actual dialogue is between God and Moses or Moses and the Israelites. There is no explicit dialogue between God and the Israelites. Given the fact that the commandements are explicitly given twice (once from God to Moses, and again from Moses to the Israelites) and the fact that Moses had to continuously trek up the mountain to relay God's wishes, indicates that God was not in direct communication with the people. This undercuts the notion that God clearly revealed himself (especially since he appeared as a natural phenomenon) to ensure that he would be taken seriously. The illustrate this point, consider that, once Moses disappeared, the people couldn't wait and decided to make their own gods for themselves (1). So how can we put any significance onto this revelation when, when out-of-side, people failed to continue to take it seriously? Proof #2The verses cited only warn against prophets whose predictions come false, or who contradict God's word: That prophet or dreamer must be put to death for inciting rebellion against the LORD your God, who brought you out of Egypt and redeemed you from the land of slavery. That prophet or dreamer tried to turn you from the way the LORD your God commanded you to follow. You must purge the evil from among you. - Deuteronomy 13:5 You may say to yourselves, “How can we know when a message has not been spoken by the LORD? ” If what a prophet proclaims in the name of the LORD does not take place or come true, that is a message the LORD has not spoken. That prophet has spoken presumptuously, so do not be alarmed. - Deuteronomy 18:21 & 22 It should be noted that the context of the first verse is to warn against anyone attempting to incite worship of other Gods and the context of the second is to explicitly prepare the people for the coming of the prophet, and was offerring advice as to how to prevent them from accepting false prophets while waiting for the true one. SummaryBased upon the proofs provided, there is nothing to forbid the validity of future additions to the Bible. If anything, the first Proof establishes the manner in which God would reveal himself to people: through mortal third-parties, ambiguously, and under the cover of natural phenomenon. The second proof places limitations or warnings regarding prophets, but does not forbid them outright. [1] . http://www.biblegateway.com...
