The Christian doctrine of the incarnation says more than that God comes to us through people, with which presumably many religions agree. It says that God is a person. This seems to me to create a kind of idol out of the personal.
I see it rather differently - that the essence of being is personal. Something that seems worth pondering in this depersonalized age of ours, when we are so given to making idols of movie stars, rock musicians and even politicians. Indeed, it is because of this emphasis on personality (in contrast to celebrity or mere self) that what Mark says at the end is so true:
... Christianity doesn’t do away with the reality of evil. Rather, it stares it in the face.
