Although individual, formal organizations, commonly identified as "institutions," may be deliberately and intentionally created by people, the development and functioning of institutions in society in general may be regarded as an instance of emergence; that is, institutions arise, develop and function in a pattern of social self-organization, which goes beyond the conscious intentions of the individual humans involved.
Having read this on wikipedia, maybe we are an institution!
Anyway I don't really care what we are, how we organise just as long as we are like this:
The church exists for nothing else but to draw men
into Christ, to make them little Christs. If they are
not doing that, all the cathedrals, clergy, missions,
sermons, even the Bible itself, are simply a waste of
time. God became a Man for no other purpose.
— C. S. Lewis
You'll find with most movements and even a to a degree institutions there can be a lot of discussion at the core about how things should be and the direction we should be heading, but most people who are distant from that, out at the coal face, tend to just do what they do and are happy and trusting of their leaders.
