The heart of the Quaker message does not lie in a doctrine expressed in abstract terms, but in an experience of power and grace, known in our hearts and also related to the structure of the universe; also known individually and recognised as belonging to all. At the same time this universal spirit is focused and made personal in Jesus in a way which makes it appropriate to speak of the Universal Light as the Light of Christ. It is from this double emphasis on universal and Christ-like that the Quaker message starts. It is these two elements, held firmly together, which provide the coherence and unity of Quakerism.
