OK,
Imagine replacing a couple of the verses in Genesis with some more "modern" equivalents.
Say it spells out the physics behind the Big Bang.
Say it says the earth is an exact figure of years old, perhaps 200 million.
Say it says humans evolved and at an exact point in time God chose to reveal himself to one of these "ape-men" and give them souls.
Now go on and read the rest of the bible. Not much has changed. Most of the links to Genesis would still work out. Jesus still came to die for our sins and save us.
Now try messing around with Matthew or John. Bad, nasty things happen. Things I'm not willing to type.
Are you willing to concede a refusal to accept Genesis verbatim whilst following the important bits is a reasonable and acceptable form of faith, albeit one you differ from?
God Bless
