Let me start out by saying this is a complex issue, you can't just point out one or two things and it is the silver bullet. There are also individuals much smarter than I am who have written and studied this problem extensively. I want to give you what I see as some of the biggest issues of the church, and suggest these are some of the issues we see.
We are living in a post-church age, where it is normal for people to not attend church. Most of the history of the United States, people just went to church. In the 60s, there was a shift that began and over the next 60 years, church enrollment has declined. The Jesus Movement of the 70s helped some, and some organizations like Promise Keepers have worked to support outreach, but the trend continues downward. I think there are some things that have supported this.
First, churches are pretending like it isn't happening. Most churches have continued on as if things are great, and there have been very few adjustments. The adjustments that we have made, I don't think, have been the best. As church membership has fallen away, many of the smaller and medium-sized churches have died and closed their doors, and we have seen the rise of the mega-church. I am not here to bash on the mega-church, it has done a lot of good, but just as much harm. It has created a culture of "consumer-based" Christianity, where the church is a combination of a concert, a nice message, some quality coffee, free child care, and a social gathering. Faith is not really required, and commitment is optional. Most mega-churches have a back door that is as big as the front door, and many of the people who attend never really commit and leave just as easily as they came.
The next problem is leadership. Not the leadership of the church, but the principle of leadership. Sure, leadership is important, but it has become the golden calf of churches. Leadership has become an idol, people love to be in charge. When someone wants to be in charge but can't, they go to one of a couple of places. They run for the city council or the school board. When that doesn't work, they find a way to become in charge of an HOA, and they find a leadership position in the church. So many places we find in the New Testament that leadership is supposed to be gracious, servant, giving, and gentile. That's not what we get, we have the CEO, Captain, General, Commander type leadership. I would dare say many church leaders do not know Jesus, they know leadership, and they just want to be in charge. Combine this with the mega church model, and you have leaders who want a big church, but not really Jesus. Joel Osteen, anyone? Without leadership who is sold out to Jesus, who is preaching Jesus, lives are not being changed, and the church is optional.
Next, gossip. In America, we love gossip. We have TV shows and magazines dedicated to gossip. In the church, we are more interested in talking about someone's struggles than we are about helping them through them. The culture at large loves it when a Christian falls. People right now know who Michael Tait is who have never heard of DC Talk or Newsboys. If you Google his name, the first thing you will see is the dirt and the gossip. Sure, we need to hold people accountable, but quietly and out of love and for the purpose of restoration. That's not what we do, we destroy people. We see people destroyed because of sin, and then we realize we have sin. I have messed up, and I don't want that plastered all over my church, do you? People stop going to church because they don't want their mistakes making the front page of the bulletin. People are afraid to be condemned.
My last point, we have left evangelism to the church. It used to be that people came to church to hear about Jesus, but not people aren't coming to church, so they aren't hearing about Jesus. We don't have outreach like we need, and church members are not sharing their faith. I know it's hard, that is why I wrote a book about it, to help make a plan and make it easier. It's still hard, but it has to happen. Christians have to find ways to share their faith outside the church, because people are no longer coming into the church. America has become more of a mission field than ever before, and we have to take missionary mindsets. People need to see their need for the church, because right now they don't.
Now, this isn't an exhaustive list, there are more reasons, and some that are church or area-specific. This is just a few places that I see big, glaring holes in the way the modern American church is operating. You can add lots of things, such as the way churches have abandoned the Bible, kids leaving after graduating, the moral decline due to social media, and all sorts of other reasons. My point is, these things we can work on in our churches today, and my prayer is to begin moving towards a society that values the gathering on Sunday morning for prayer, worship, and growth.
