A church is an organization made up of organisms. Members of the church (organisms) may have expertise in everything from investment counseling to evaluating group dynamics to operating small businesses or nuclear power plants. The organization itself, however, can have areas on which it is uniquely suited to comment. What can the church teach people?
I'll help with a list of potential areas (note, this is decidely not a list of answers I would endorse, but conversation starters), but please don't limit your responses to my examples.
