This book explains Jesus's two natures in a way relevant to the modern reader. It clearly describes the struggle to understand Jesus's two natures and points out inadequacies in the views of some church fathers who misinterpreted the meaning of Jesus's two natures. This book uses the affirmation of the Council of Chalcedon, AD 451, to explain Jesus's two natures and establish that Jesus is fully God and man. This book takes on a historical and theological stance. Still, it can be appreciated by both theologians and nontheologians because it articulates with clarity and simplicity the significance of Jesus's two natures for the Christian faith.
