Have we been sluggish in our impact in Europe because we are still trying to do church in an attractional way [designed by "moderns, boomers"]?
But those days are long gone on Europe and many parts of the USA. The assumption that people will come to our cool hip shows, has proven to be without result. Hillsong has got it right because they plant in expat communities with massive brand recognition.
For the many plants wrestling with the raw challenge of the gospel in Europe and the city shadowlands of the USA, the way they have been taught is simply not contextually clear nor culturally sensitive.
I suspect the answer lies with "Missional Communities"... not just missional. Nor just communities. But both together and that is very different form the way we have done it before.
