In short, apostolic movement involves a radical community of disciples, centered on the lordship of Jesus, empowered by the Spirit, built squarely on a fivefold ministry, organized around mission where everyone (not just professionals) is considered an empowered agent, and tends to be decentralized in organizational structure.
Because we believe that somewhere in the nest of paradigms contained in the phrase "missional church" lies nothing less that the future viability of Western Christianity.
A missional theology...appl ies to the whole of life of every believer. Every disciple is to be an agent of the kingdom of God, and every disciple is to carry the mission of God into every sphere of life. We are all missionaries sent into a non-Christian culture.
If we can embrace the adventure and risk and equip our churches to lay down their lives and abandon their inherent loss-aversion, who knows what innovation, what freshness, what new insights from the Spirit will emerge.
Most churches don't have the resources for these tricks and inducements but are still bound to the imagination that church happens on a Sunday in a building.
Many church folk, in their self-conscious attempt to be overtly morally upright, emit all the wrong signals, thus messing with people's perception of the gospel.
Whether we like it or not, we are all on a journey, a Quest if you will, every day of our lives, and the path we must take is full of perils, and our destiny can never be predicted in advance.
