Church Planting/Corps Planting

What a busy, exciting week I've had. Jo and I attended a Church Planting Conference, with guest speaker Stuart Murray, whose written numerous books, such as, 'Church Planting', 'Post Christendom' and more.

The content was helpful and interesting. We talked a little about the essentials for a church... Have a look at the limited list below and comment on which you think are absolutely essential for a Church, and are non negotiable...

* Church Building
* Prayer
* Timbrels
* Contemporary Band
* Food
* Bible exploration/study
* Soldiership
* Teaching the gospel
* Doctrinal beliefs

Which do think are negotiable? Which are absolutely non negotiable for a church?
