There are many elements in the video that I certainly agree with, but I think that there are certain things that go deeper than that. The concept of religious organizations being social clubs is not new.
Also, some churches are already making modifications, some attempted to become "cool churches" offering rock concerts and other events to appeal to people.
Another challenge that they face is that some of their attempts at becoming nonprofit organizations with programs to help the community is that their believes and practices discriminate against many of the communities that they are supposed to serve. I cannot imagine a church having a needle exchange program, or a HIV education program for transgender prostitutes, or services for single parents, or (horrors!) a women's health clinic that provides the means for abortions.
Because of their believes and practices, they cannot obtain a lot of funding from government programs.
