You sound like you are a bit cross. Sorry about that.
You seem to believe that the RCC is doing all the heavy lifting and other Christian demoninations (really? Everybody who is not a member of the RCC is a Christian "spin-off" group? That's a new slam I hadn't heard before. Of course, that would make the RCC a spin-off from the original Christians -- the Orthodox, but we won't pay any attention to that. Facts are so inconvenient when we're trying to just have a little fun being judgmental) are sort of sitting back?
Well, that's untrue, as I'm sure you know. Lots of major, important stuff is being done by other denominations and other faiths.
In the USA, we would not even have a rehabilitation movement, were it not for the many organizations that have Jewish roots.
Every denomination has major helping organizations, on the ground, doing what needs doing, and many cross-cultural organizations have no ties to any specific faith, although they most definitely are Christ-centered.
Knowing this, it makes your post seem a bit -- misinformed or willfully misleading.
Maybe it's time to put down the pipe and get going doing a bit of research, cuz if you check out the web, the facts are really fairly easy to come by. Assuming you actually want to find facts, of course.
