@paterfamilias, I've got to be honest with you here. Being in agreement on spiritual matters with your wives is crucially important. There is a fundamental principle here which you have no doubt heard before - Christians are explicitly instructed to not be "unequally yoked with unbelievers". In other words, when we are working alongside someone much of the time ("yoked"), we need to be in agreement on much more than just the job at hand. This applies to all of life - it's why people tend to gravitate towards people of the same religion and politics in business for instance - but applies most strongly to marriage, because that is the part of life people are most closely yoked together.
2 Corinthians 6:14-18 said:
Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?
What accord has Christ with Belial? Or what portion does a believer share with an unbeliever?
What agreement has the temple of God with idols? For we are the temple of the living God; as God said,
“I will make my dwelling among them and walk among them,
and I will be their God,
and they shall be my people.
Therefore go out from their midst,
and be separate from them, says the Lord,
and touch no unclean thing;
then I will welcome you,
and I will be a father to you,
and you shall be sons and daughters to me,
says the Lord Almighty.”
So, much as you seem to be a great guy, I don't think a Christian wife is what you should be looking for.
You're really looking for a morally conservative wife. You are considering a Christian one simply because where you live most atheist women are nuts, and it's only the Christians that have remained sane. And I can completely understand that attraction. But this conservative culture that you value can only be preserved by marrying those same Christian women off to other Christian men who will create Christian families that will continue that culture. Marrying outside the faith, even to a decent man, is the first step towards diluting the influence of Christianity on the culture, and ending up with the very liberal atheist culture that you despise.
Cultural Christianity - the philosophy held by conservative atheists like yourself, Richard Dawkins and others - is a short-term phenomenon that appears during the change from a Christian culture to a non-Christian culture. You cannot hold onto it. It will disappear in a generation or two. It is simply nostalgia. And when a "cultural christian" - an atheist who likes conservative culture - marries a Christian woman, because he is dominant in the marriage, the children will simply not end up holding those values strong enough to preserve the culture. It has to be grounded in genuine faith to be preserved for multiple generations, and most of those children will not have such a faith.
Christians are the "salt of the world", the ones that preserve it. The only way to preserve the culture that you value is for those few rare conservative Christian women to marry conservative Christian men and raise children who have the same faith.
I know those women are incredibly attractive to anybody. I can completely understand why you want one, or more than one - they're awesome. But they are not just there to be enjoyed by one man, they have a crucially important job to preserve a society for all men. And this is why Christians have always been careful to try and marry their daughters off to other believers. That is how the culture you love was preserved for centuries, and it is the only way to preserve it for the future. There have always been some Christian women married off to other men - even Muhammad married one I believe (which explains much of the Christian flavour of the Quran). But the majority must marry Christians in order to sustain the culture, and as they become rarer this becomes more crucial by the year.
If you want a Christian wife, find Christ first. Then marry one and you can be part of the solution, rather than just someone who simply enjoys the fruits of a belief system that you do not share and are not yourself going to grow and spread.
We've got our eyes on a much larger mission here than just our own private marriages.
