Ashley, I have found the following helpful in at least one couple's situation. I referred them to Dr. Todd Wood's blog and various articles, mainly for his comments on how he can be a Young Earth Creationist while emphasizing graciousness towards those who disagree and while demanding honesty when describing what the Theory of Evolution states (and with what scientists have to say about the evidence.) At least with the couple I was advising, they both agreed that Dr. Wood's approach to origin's topics was one which they both could respect and find informative. They both seemed very relieved that a congenial approach was possible.
Dr. Wood avoids the false dichotomies and the reliance on angry mantras which one often experiences in origins debates. And when a marriage and children are part of the disagreement, Dr. Wood's approach seems to encourage a cooperative approach instead of a strict reliance on drawing up "sides" for a war.
I've often wished that Dr. Wood's objectives would be appropriated by more Christians who debate origins topics. I don't agree with many of Dr. Wood's origins positions but I have tremendous respect for his pleas that all Christ-followers do their best to be Christ-like even while disagreeing.
He's an example of Dr. Wood's views on how we should approach origins topics:
"Let me leave you with another chilling possibility. What if we teach the next generation that there is no evidence for evolution? And what if we're wrong? What do you think will happen when those kids find out? I think what will happen is the same thing that always happens. They'll be disillusioned and fall away from the faith. I've heard of this happening, and I've seen it happen. People find out that all the antievolution arguments in the world won't survive a semester of basic biology at a secular university. While we thought we were teaching them to believe in Christ, we instead taught them to idolize our arguments about Christ. And when those arguments are shown to be incomplete, inadequate, or just wrong, that idolatry (which we thought was real faith) slips away.
That's why I want my students to know the truth about evolution. It's not bogus. It's not a failure. There's lots of evidence in its favor. But that just doesn't make it true. Have faith in the risen Christ, and it will not matter what scientists tell you (or anyone else, for that matter)."
I like the way he points us to keeping priorities in perspective.
