Here's the thing about making assumptions and presumptions about the Body of Christ ... the Church ~ I'm almost always and inevitably proved wrong. Yes, the microwave had a sign on it for a couple weeks. Yes, in the corporate world, a CEO or other manager would have directed an underling to take the broken appliance out right away ... or would have praised and promoted a mid-level manager who took the initiative to take care of that issue without any instruction. And yes, I could have directed someone to take care of it, putting myself in the role of congregational CEO.
But church is not (or, maybe, ought not be) corporate. It may take a little longer, but in a healthy church system, those who are called to a particular responsibility will take on their job at the appropriate and proper time. At the end of the day, the microwave was disposed of by the team who had, long ago, accepted the responsibility of maintaining the congregational facilities.
Sometimes, obviously, corporate life is more efficient than life in the church. But I prefer the (ideally) egalitarian, though much slower and messier, life that the Church (Body of Christ) models and embodies.
