A Few Questions about the Business of Church

My college degree is in accounting. My master's degree from seminary is in church administration and communication. I have done additional post-graduate work in church business administration; I am a certified Fellow in Church Business Administration. I have been a member of the National Association of Church Business Administration since 1992. I just returned from that group's annual meeting in Long Beach, and I have a few questions:

• Why is one of the largest gatherings of church administration types getting grayer?
• Where are the administrators of non-denominational churches?
• Do these administrators network in any fashion?
• What is the value of peers coming together, digitally or in person, to support one another?
• Is a new model of "church administrator" coming into being?
• Isn't the operation of whatever you call "church" becoming more complex? How do you manage it, then?

Just thinking...
