Here’s some good news. It seems that even Christians are starting to doubt the continued existence of evangelical Christianity with one writing in the Christian Science Monitor that he expects it to collapse within our lifetimes (source):
We are on the verge – within 10 years – of a major collapse of evangelical Christianity. This breakdown will follow the deterioration of the mainline Protestant world and it will fundamentally alter the religious and cultural environment in the West.
Within two generations, evangelicalism will be a house deserted of half its occupants. (Between 25 and 35 percent of Americans today are Evangelicals.) In the "Protestant" 20th century, Evangelicals flourished. But they will soon be living in a very secular and religiously antagonistic 21st century.
It couldn’t happen to a more deserving group in my opinion. If there’s one group of Christians I’d described as bone-deep stupid and rabidly hateful – it’s the evangelicals. The author of the piece apparently agrees with the first half of that description as he lists ignorance as one of the reasons this is going to happen.
