JR Woodward is an American church planter, organizational leader, entrepreneur, author, academic, and leader. His foremost interests are in missional theology, missional leadership, theology and film, spiritual formation, and organizational dynamics (see his website for a full biography).
The main argument (thesis) in Creating a Missional Culture is that the unseen culture of a church is what most powerfully shapes its ability to grow, mature, and live missionally, more so than its vision, strategy, and plans (Location 211). Woodward supports this thesis through four sections that each address a different aspect of that powerful unseen culture.
In the first section, he talks about the force of culture in life, society, and in churches. He then addresses how leaders need to be aware of just how powerful culture is in shaping their leadership style and the life of a church. He concludes this section by introducing the concept of polycentric leadership: leaders as apostles, prophets, evangelists, pastor, or teachers.
