Denominations are a Nasty Stumbling Block

I wrote this a while back.  Haven't changed my mind.  In fact, I'm liking the def more and more every time I read it.

".....a denomination functions essentially as a large, disconnected, mega-church that typically is founded around ancillary, divisive doctrines.  Over time it eventually becomes nothing more than a centralized, bureaucratic, para-church corporation.  I understand this whole structure to be impersonal, having no biblical warrant, and a nasty stumbling block to fellowship between other Christians and congregations."
