There is no doubt that those following organised religion do very good work. The fairly obvious point is that following these or holding a strong personal faith - is not a prerequisite for doing good work.

Equally good works are undertaken by many non religeous bodies and individuals. Perhaps these folk are able to concentrate fully on these tasks and not be compromised by the demands of their organised calling? Or possibly sometimes be distracted when the the voices in their heads and the visions in their eyes - conflict with the feelings in their hearts?
