Studying in America in the 1960s meant I'd met with Liberation Theologians before their work got back to England. Most was written in academic terms so I simplified and translated it into a visual circular diagram. My working-class parishioners helped refine it. Until then theology was taught as theory to be 'applied' to situations, but this new method recognised that if we reflect on what God is already doing in situations a more vibrant form of theology results. 

After some years, in 1987,I published 

my first book Power to the Powerless describing how a parish was transformed using this 'Contextual' approach. It was all so new it was named a Book of the Year by the Church Times. 

There are now many using the contextual theology approach and in my revised edition of Let's Do Theology I describe some of those models, but they all begin by concentration on the experiences God gives us in the world.
