There are times when it's easy to forget how many moral and cultural changes have taken place in North America, and the world, during the past half century or so.

When it comes to news, the tendency is to focus on stories that create the flashiest headlines. In the world of religion news, most of those have focused on LGBTQ issues. How many reporters will flock to the scene when the Episcopal Church consecrates its first trans bishop? Quite a few, it is safe to say.

However, when you look at statistics, even bigger changes have been taking place elsewhere -- among the lives and, from a biblical point of view, the sins of others. For example, if you talk to pastors -- in the most conservative, traditional churches -- you will discover that one of the most divisive issues they face, week after week, is how to handle the weddings of couples who have already been living together. Often the hottest arguments are with the parents of these young, or not so young, people.

This brings me to an interesting think piece in Christianity Today that ran with this headline: "The Three Myths of Cohabitation." As you would expect, CT knows that there are religion angles in this topic. However, for mainstream news reporters, this is a question-and-answer interview that is haunted by news angles -- national and global -- for those with the courage to cover them. Here's the overture:

According to a recent sociological study, cohabitation has a notably deleterious impact on one particular group: kids. “As marriage becomes less likely to anchor the adult life course across the globe, growing numbers of children may be thrown into increasingly turbulent family waters,” writes Bradford Wilcox in Foreign Affairs.

A professor of sociology at the University of Virginia, Wilcox and his colleagues recently completed a new study, The Cohabitation-Go-Round: Cohabitation and Family Instability Across the Globe. The report is the fourth edition of the World Family Map project -- which tracks various indicators of family health -- and is sponsored in part by the Social Trends Institute and the Institute for Family Studies.

The main study included the United States and 16 European countries. “We were looking at the odds that kids who were born to married or cohabitating parents will still be with their parents when they turn 12,” says Wilcox.

At the heart of the interview, obviously, are "three myths" about this widespread global trend in sex, marriage and family life. There is no way to sum this all up.
