They already exist. Rick Warren argues in The Purpose Driven Church that this is exactly what denominations are -- simply different flavors of Christianity that suit different personalities. And also, now, there are Purpose Driven churches, Willow Creek churches, & Northpoint-style churches. Is this like having McDonald's vs. Chick-Fil-A?
The writer of this particular article asks these questions:
Is this the future of the Western church- franchised congregations of megabrands in every city with pastors serving as the local owner/operator?
[...]
What do you think? Are (these churches) and other franchised congregations the wave of the future? Are Chick-fil-A and McDonalds the right model for the church to be emulating? Are franchised mega-churches going to be the denominations of the 21st century? Or, is this consumer Christianity taken to its logical and disturbing extreme?
I have one question to add: does the 1st Corinthians passage about unity ("I'm of Apollos, I'm of Cephas, I'm of Paul, I'm of Christ...") bring anything to bear in addressing this issue? That is, in terms of churches making the statement, "I'm of Rick Warren, I'm of Bill Hybels, I'm of Christ, etc."
What say YOU?
