Uh, Joaquin, I'm trying to figure out the connection you see between these passages and Your contention that Paul did not interpret the Law and the Prophets literally. What Paul railed against, as did Christ even more vociferously, was people like the Pharisees who were pious religious zealots, but whose hearts knew the true and living God not at all. It was a game to them--whoever washes their hands better, dresses more piously, gives the biggest sacrifices, wins. Paul followed Christ, and Christ clearly taught the literal 6-day creation.
Paul directly rejects literalism in this passage.
1 Corinthians 9:9 For it is written in the law of Moses, "You shall not muzzle an ox when it is treading out the grain." Is it for oxen that God is concerned?
Paul says, it's literally about oxen, but that's not what it means -- "Is it for oxen God is concerned". No, Paul answers, the law is a symbol of paying those who do service, in this case, ministers like himself.
10Does he not speak entirely for our sake? It was written for our sake, because the plowman should plow in hope and the thresher thresh in hope of a share in the crop.
Entirely! The entire meaning of the passage is not literal. It isn't about oxen. It's symbolic for a relationship between ministers and their flock.
This is how Paul interpreted the entire Hebrew scriptures (since of course there were no Christian scriptures at the time). And this is why he says that they for "instruction." They aren't geology books, but texts that instruct us on how to live. If you take them literally, you miss the instruction, which is the purpose.
Romans 15:4 For whatever was written in former days was written for our instruction, that by steadfastness and by the encouragement of the scriptures we might have hope.
Thus Genesis is for instruction -- not for biological knowledge. And thus it is symbolic, moral, spiritual. Thus:
2 Timothy 3:16 All scripture is inspired by God and profitable for teaching, for reproof, for correction, and for training in righteousness,
(although Paul probably didnt' write Timothy its from the school of Paul).
As to Jesus, he also rejected literalism. Quoting Genesis 2, he says:
Matthew 19:5 and said, 'For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh'? So they are no longer two but one flesh. What therefore God has joined together, let not man put asunder."
But of course Jesus doesn't believe married people become one blob of flesh. He doesn't take it literally (nobody can). Married people do not literally become one flesh. They only do so metaphorically. It has a spiritual meaning.
So unless you think Jesus actually believes married people become a single blob of flesh, he doesn't take Genesis literally.
