GRAPEVINE (CBSDFW.COM) – Is adultery in your DNA?

That was the topic that two men were debating on Thursday night. In one corner, the founder of a website designed to assist married men and women in setting up affairs online. In the other corner, the pastor of a North Texas mega-church.

Ashley Madison is the matchmaking website that helps people cheat on their spouses. Founded in 2002 by Noel Biderman of Canada, the site has grown into a multimillion dollar company. According to Biderman, the service that his website provides is helpful. “For a lot of people, it’s a marriage preservation device,” he said. “It may be an unhealthy marriage preservation device, but it is a preservation device.”

The site has more than 140,000 members in the DFW area alone. This is Ashley Madison’s second-fastest growing market.

Ed Young is the founder and senior pastor of Fellowship Church. He responded by saying, “It does not take Dr. Phil or a relational rocket scientist to say that is wrong.” Young believes that it is time to put God back in the bedroom. “Let’s bring the bed back in church, and God back in the bed. I believe when you do that, it’ll take your marriage and your life to a whole other level.”

To really drive that point home, in 2008, Young brought a real bed into his church. Lisa, his wife of 29 years, said, “I grew up in a home where sex wasn’t even talked about openly. So, these are things we want to not only communicate to our children, but also to our church.”

Young did have home-field advantage during this debate, which was held at Fellowship Church. A number of church members attended to learn more about the topic, and cheer on the pastor. “I think it’s messed up that somebody would do that,” said Dan Baldis – who actually attends another church – about the Ashley Madison website. “I want to see Ed Young just kind of nail it.”

This was not the first time that Young and Biderman have debated on this topic, and they did not rule out another debate in the future. So, while the crowd may have been behind Young on Thursday night, there is no telling where this conversation will go the next time that they meet.
