Peter Tyler endeavours to represent St John of the Cross in the truest light, covering his life from the angles of John as Theologian, as Mystic, Psychologist, and Artist. Tyler draws parallels, at times uncomfortable, between the age of disruption and and change in the church during which St John wrote, and our current age. In so doing he makes the case for this controversial, but largely misunderstood, figure to be an important guide for practical theology today.
