I can list things all day long that our church does that is helpful to all. We sent people to build for Habitat after Katrina as well.
However, I must concede to wilheldp that there are corrupt churches, there are those who are only after collecting money, there are many bad TV evanlegists, etc. etc.
My wife was born and raised Catholic, and I married her in the Catholic church, but she has now been United Methodist for the last 4 years, and she even stated that after seeing all the things our local church does, she can't name a handful that her old Catholic church did for the local community.
So it is different from church to church, and there are some bad apples. But wilheldp, don't let those bad apples be the example of what the whole big picture is. that is selling it short.
