What does “church size dynamics” have to do with Christ Community?

2010 stands out, to me, as the year that Christ Community successfully transitioned from living and thinking like a “small church” to that of a “medium size church”.  Below is a small piece of an article Tim Keller wrote called Church Size Dynamics.  At the end of my excerpt is a link to a longer excerpt.  If you want to go straight to the 15 page doc, cheers.

We tend to think of the chief differences between churches mainly in denominational or theological terms, but that underestimates the impact of size on how a church operates. The difference between how churches of 100 and 1,000 function may be much greater than the difference between a Presbyterian and a Baptist church of the same size.
A large church is not simply a bigger version of a small church. The difference in communication, community formation, and decision-making processes are so great that the leadership skills required in each are of almost completely different orders.

Size Cultures

Every church has a culture that goes with its size and which must be accepted. Most people tend to prefer a certain size culture, and unfortunately, many give their favorite size culture a moral status and treat other size categories as spiritually and morally inferior. They may insist that the only biblical way to do church is to practice a certain size culture despite the fact that the congregation they attend is much too big or too small to fit that culture.
