If you have been interested in the multisite discussion as a missional church, then I’d recommend reading the article below. Todd Wilson does a great job of highlighting the upside of multisite planting, and a holistic perspective on how it fits with church planting strategy.
I think the theory of the article is spot on, but there is one key phrase in the article that a church must wrestle with:
If you take anything less than a very healthy process, whether it’s your children’s process, newcomer assimilation process, worship process—any process you have—when you copy it, if it’s unhealthy, it may become even more unhealthy than the original. On the one hand, your church might be growing rapidly beyond the current capacity of your leadership and systems. On top of that, you may be copying less than vibrant and healthy processes and systems. The result can be sideways energy that further slows you down.
The key to a successful multisite launch will be the health of your existing organization, which is a good motivation to do some deep assessment prior to launching.
Great thoughts to consider!
