Eg. should the fact that some of Dawkins research and hypothesis into and of genes is being shown to be outdated discredit all of his research?
If Dawkins was claiming to be God, or a spokesperson for God, then... yeah.
If the Bible writers were writing as spokesmen for God, but they occasionally got
a few things completely wrong, how are we supposed to know what they got
RIGHT? If they screwed up the flood story, how do we know they got the
homophobia correct?
We have to remember that much of the Bible, including the really significant
moral stuff, is based on the "Because I Said So" system. That system only works
if you can PROVE you are all powerful and all knowing, and one way to do that
is by writing something only an all powerful/knowing entity COULD write.
If your piece of writing has some things right and some things wrong and you
leave it to the good sense, science, and conscience of your future readers to
figure out which is which, you are left with a work that is indistinguishable
from a man made document, and can only reasonably be treated as such.
