I work in a church, and live near several "seeker sensitive churches". I am always amazed at how quickly staff members of churches rise up to criticize and tear down their fellow brothers and sisters. While I think most church marketing sucks, there are a few notable exceptions in my area. Churches that seem to be on the cutting edge of marketing, constantly working on new and creative ideas for their church series. I love driving by Flamingo Road Church simply so I can see their enormous billboard out front announcing the next series.
I think the impetus for most of our criticism comes not from some divine mandate that we constantly be on the lookout for those who are "compromising the message", but rather from our own jealousy. I don't really hear much criticism about churches of 20 in the area, but rather only about churches with large membership roles.
Ministry envy seems to be at an all time high, and it's continually frustrating to me to hear people tear down other pastors. My feeling is this: Before you criticize another pastor, or ministry, you should be required to first visit that church, and have lunch with that pastor. You should visit his home, meet his family, and church staff. Find out what they are all about. Walk a mile in their shoes. Only then will you be qualified to criticize, or judge their ministry. Throwing stones from a distance is far too easy.
There are many reasons why I think church marketing sucks, and I'll probably delve into that topic later... I'm continually frustrated that the church is not the hub of creative activity...
