The Gospel of John ('the Fourth Gospel') is presented through the symbol of a diamond. With the motif of light dominant from the opening Prologue culminating in the saying of Jesus, 'I am the light of the world', the symbol of diamond draws on this to indicate the constant inter-flow of its method and style. Like light falling on a diamond and flowing from facet to facet the themes of the Gospel of John are highlighted and held together. This creates a dynamic which is circular, drawing those who read and pray the Gospel into a deeper understanding of its spirituality and theology.
