This is not your normal headline for a Christianity Today think piece: “Polyamory: Pastors’ Next Sexual Frontier.”

Then again, while teaching at Denver Seminary in the early 1990s, I kept seeing studies suggesting that there was little or no difference — in terms of mass-media patterns — between ordinary American consumers and people living in “conservative” or even evangelical households. Did anyone expect this to slow down in the Internet era with its omnipresent screens?

The question that has emerged: Are evangelicals attempting to evangelize their culture or is the culture, via media, slowly but surely evangelizing them? Here’s another newsworthy angle to chase: Are media habits linked to emerging fault lines inside evangelicalism today?

But back to this provocative, to say the least, CT thinker from Preston Sprinkle, leader of the Center for Faith, Sexuality & Gender, and Kuyper College theology professor Branson Parler.

The context for this? Many pastors today are still struggling to know how to handle the marriage requests of evangelical couples who are “shacking up,” to use the old school language. Now this:

A pastor recently told me (Preston) about Tyler and Amanda (names changed), high-school sweethearts raised in Christian homes, living in the Bible belt. After getting married, they seemed to be living the American dream with a house, good jobs, and two kids. Then Jon, a friend of Tyler’s, began living with their family. Amanda developed a close relationship with him, but their flirtation soon developed into something more, and Jon and Amanda proposed to Tyler that they begin exploring polyamory, with Amanda adding Jon as a significant other. They also encouraged Tyler to develop a relationship with another woman he’d met at the gym. He agreed.

When Tyler and Amanda came out as polyamorous, their parents were shocked. What seemed like a fringe practice of the sexual revolution had settled into the heartland of Middle America.

Making the situation even more complex, Tyler and Amanda sought counseling from a Christian counselor who advocated polyamory.
