What do you do with the Ten Commandments where Moses tells the Hebrews to set apart a Sabbath and keep it holy because God created everything in six days then rested so man, created in God's image, should do likewise?
The same way that Augustine did. Just because there was a figurative six days in the creation ... in what God revealed of creation ... then his using those figurative days as the basis for setting apart a seventh day (which never ended in the account, so it still continues) is perfectly logical. In fact, it could be (a conjecture, but totally unnecessary to the interpretation) that the reason for the figurative six days was explicitly to provide for a sabbath rest.
Brian, you said:
The reasons that you state for concluding that the passage has to be figurative does not follow. If God said that there was light before the sun, moon and stars, all it means is that He created light before the sun, moon and stars....
For what you to say to be the proper interpretation you have to have the conjecture that the first three days just happened to be 24 hours, when the 4th day was when 24 hour days as we know them were created. That is a sufficient reason to believe the days of creation are figurative. It might be possible to find an implausible set of circumstances for justifying a literal interpretation, but the same is true of the implausible idea that the sun moves around the earth. Is it possible? Yes. But it is certainly not what we have to believe in order to have the text of scripture inerrant and infallible.
My principles in looking at the passage are: First, the Bible is without error. Second, the simple interpretation is probably correct more often than a complicated conjecture. Third, internal consistency of a passage is stronger than attempts to force consistency across books (an extension of the first point). Fourth, in those cases where the scripture is unclear, it should be interpreted by other more clear passages.
I believe I have met all four of these principles with a framework interpretation (and I don't even have to look at the fourth, as the passage is clear in situ).
I've established a logically reasoned support for a framework interpretation. That is, I have shown that it is not pure conjecture, it is based on the text itself, and that it is in accord with the rest of scripture. At that point, if someone wants to convince me otherwise, it is up to them to prove what I have said is false, not show that it is possible that there are other interpretations (including the 144 hour creation).
What I find rather absurd is that people are demanding that there be an absolute proof for anything other than 144 hour creation, when in fact all that is required logically is that it be more likely that it is figurative. I am not trying to prove that it could not be 144 hour ... I'm saying that I believe it was a framework and figurative. I've given reason for that, and while people are saying that does not prove it was not literal, I do not believe that is what is required here. What is required is a logical exegetical view of the passage that fits not only the passage in question, but the rest of scripture. It is not my goal to prove beyond any doubt ... neither should your goal be to prove 144 hour beyond any doubt.
While I do not think 144 hour interpretation of Gen 1 is correct, I can see it is minimally reasoned, it is not pure conjecture (though I believe it relies on conjecture for parts), that it does not conflict with the rest of scripture. With that, I would not want to attempt to prove it wrong. I can give reasons for my disagreeing with it, give my opinion as to why I hold a different viewpoint. But just like other passages that are not explicit to what the whole church believes (anyone for a post, pre, or a mil debate?) there is room for disagreement and fellowship.
