Mark Driscoll gives a helpful definition of the local church from his book, Vintage Church:

The local church is a community of regenerated believers who confess Jesus Christ as Lord. In obedience to Scripture they organize under qualified leadership, gather regularly for preaching and worship, observe the biblical sacraments of baptism and communion, are unified by the Spirit, are disciplined for holiness, and scatter to fulfill the great commandment and the great commission as missionaries to the world for God’s glory and their joy.

I'm also intrigued by Jonathan Dodson's concise definition of the church:

A community of missionaries created by the Spirit on the mission of Christ.
