Gregory’s narrative of the human person as an image of God is summarised best as ‘divine, yet vulnerable’. This reflects Gregory’s multifaceted approach, which relates to both human nature and experience. My use of ‘vulnerable’ is not intended to suggest that God might wound the image of God in any way; rather it is applied to indicate a kind of openness which may be positive or negative. The image of God is positively vulnerable (or porous) to God, having been created with the purpose of becoming ‘divine’, but at the same time negatively vulnerable to ‘the world, the flesh and the devil’.
