If someone calls themselves a Christian and say they believe in evolution, then they are calling God a liar. So they can't be Christians. "In the beginning, God created..." It says so, right in the Bible.
Not really, someone can believe the genesis story is allegorical and that God initiated evolution as his mechanism to create man in his image.
I think it's unlikely that was the author's intent with genesis, but it is less stupid than your belief that it is literal and therefore all the science
it defies is wrong. I think those people are coming to an uncomfortable accommodation, and you should let them. Their only alternative
is to leave the fold or accept your narrow, rigid exegesis? Your membership will winnow down from a global religion to the population
of Mississippi.
