Notable Christians Open to an Old Earth Interpretation
The title of the link that you suggest indicates that perhaps you didn't follow the implications of what the quote that P-M posted actually said.
It said, "no professor...does not believe..the writers...intended to convey...creation...of six days..of 24 hours..."
Since that is the straight-forward reading of the passage, then to say that it is what the writers "intended to convey."
Your link uses the word "interpretation." That suggests taking the OBVIOUS and applying a methodology to it in order to arrive at an understanding.
The quote above is dealing with the "obvious" PRIOR TO the interpretation.
And the straight-forward, obvious look at the passage says, "6 days."
It is indisputable.
"It is indisputable"
It's only indisputable if you neglect the contradictions young-earth causes. In biblical study there's a huge difference between superficical reading and in-depth exegeis. Young-earthism is the former rather than the latter.
