What theological method does Rowan Williams employ?

Archbishop Rowan Williams seems to be attempting to chart a path through late twentieth-century philosophy and culture to reach a place of faith in God as mediated through the Christian scriptures. He speaks frequently of God's hiddenness and difficulty. His books are very dense and hard to understand, requiring slow and thoughtful reading.
Williams received his doctorate from Cambridge for his studies of a twentieth-century Russian theologian, Vladimir Lossky. During his undergraduate years he also began to read the works of Donald MacKinnon, a British philosopher and theologian. MacKinnon's writings have been a profound influence on Rowan's thought.
To quote Benjamin Myers, the author of Christ the Stranger: the Theology of Rowan Williams, " 'God,' Williams once wrote, 'is what we have not yet understood, the sign of a strange and unpredictable future.' "
Williams seems to be saying that when we look for black-and-white answers to moral questions, we fail to take into account the tragic dimension of life and to see how God's grace is being worked out in our real and sometimes very broken lives.
