This volume Who Is Your Father? could include the sub-title, And Who Are You? Based on John's Gospel, the title is taken from John 8:19, 25 and 53, a conglomerate of the three pertinent questions asked of Jesus by the Jews, 'Where is your father? Who are you? Who do you think you are?'.

 The chapters are based on teaching delivered in a pastoral setting and seek to express the truth that John's is truly the Gospel of the Father.
