“Christ is the supreme human example, who evinces an authentically human lifestyle which we are alleged to be capable of imitating. Such a view is not merely adequate as an exposition of the significance of Jesus Christ, but is unrealistic in its estimation of the capacities and inclinations of human nature. It is an ethic addressed to an idealized humanity, which does not correspond to humanity as we empirically know it, and as we have been taught to view it by the Christian tradition, trapped in its predicament. Perhaps the most characteristic feature of sin is self-deception, a reluctance to accept the tragedy of our situation…This ‘moral example’ theory rests upon a totally unrealistic and un-Christian view of human nature.”

Alister McGrath, A Passion for Truth (p. 42-43)
