It stands to reason that if one book of the bible is wrong then every subsequent book that makes reference to it within the bible is wrong.. if thats the case wouldn't that unsubstantient the entirety of the works?
We take claims one at a time. So your premise is in error: that all the Bible must be true in order for any of it to be true. What's more, there are different types of trut. You apparently are reading the Bible literally instead of how it is supposed to be read: as a
theological document. Genesis 1 was not meant to be history; it was meant to be a theological refutation of the Babylonian religion. It does that very well. Genesis 1 tells a
theological truth, not a literal truth of history.
Let's take this out of the Bible for a bit so you can see that we do not apply the criteria you are using.
First, let's look at Shakespeare's
Macbeth. It is set in a fictional history of Scotland. None of the events depicted actually happened in history. Yet the play remains popular because it tells truths about human nature: lust for power, corruption by power, guilt, justice, etc. Those are truths even when set in a not-true history. Just as Macbeth can tell human truths in a fictional history, so can the Bible tell theological truths even tho some of its history is wrong.
Second, let's look at
Origin of Species. Darwin got some things wrong in that book. For instance, he ascribes the loss of wings of a species of beetles on some islands to use/disuse. Does that make evolution wrong? Of course not. That is one claim. It being wrong does not negate the accurate claims in the book.
So assuming this to be the case, we would have to state that since Yaweh either didn't write the bible or he was mistake in what he himself said he did or claimed to be true, that he was not elohim meaning Jesus (who is reffered to in the bible as the son of adam) who shared the exact same understanding of the creation of the world that his father did was in fact incorrect as well..
There are a few logical problems here.
First is the premise "Yahweh wrote the bible". Jesus tells us in Mark 10 and Matthew 14 that Yahweh did not write the Bible. Jesus says Moses did. And Jesus is referring to the only "bible" in his day -- the Pentateuch. Also, Jesus says the bible contains mistakes. Jesus says this in the same chapters. He is referring to Deut 24:1 and says it is a mistake.
Second, Jesus did have a correct understanding of creation. Whenever Jesus refers to any of the Genesis stories, he refers to them correctly: as
theological truths. In Mark 10 and Matthew 14 he uses creation of men and women in Genesis 1 as a basis to say that divorce is wrong. It doesn't matter that God created humans male and female by evolution; He still created them male and female. That is what is important. When Jesus refers to the Flood, he does so as a metaphor for not being prepared, not as history.
You cannot say the bible cannot be taken literally and say you believe in Jesus because Jesus said "A man shall not live by bread alone but by every word of God" and since the bible is the word of god you by not living by it are directly contradicting the Person you are basing your belief system on.
The foundational creeds of Christianity are the Nicene and Apostle's Creeds. They state what it is necessary to believe in order to be a Christian.
Neither of them state a literal Bible is necessary to be a Christian. So it is very possible to be a Christian and say not all the Bible is to be taken literally. Some parts of the Bible do need, of course, to be read literally. It was not a figurative Resurrection, for instance. We believe Jesus did literally resurrect. Nor was it a figurative creation. God did create. But we do not have to believe a literal reading of the Bible on
how God created. The different stories of creation (and yes, there are more than one story of creation in Genesis and they contradict) are not literal history.
I would also have you look in Acts to the story of Paul and the jailor. What did Paul say was necessary to believe? Did he mention anything about a literal bible?
What you are doing here is trying to add something as necessary to Christianity that is not necessary: a literal bible. Instead of focussing on God and Jesus (and in particular your personal relationship with God), you are focussing on the bible. If you have a personal relationship with God (Jesus), you
don't need the bible at all. The bible, in fact, is only a tool to help you find that personal relationship. The bible is not an end in itself.
