When a man no longer confuses himself with the definition of himself that others have given him, he is at once universal and unique. He is universal by virtue of the inseparability of his organism from the cosmos. He is unique in that he is just this organism and not any stereotype of role, class, or identity assumed for the convenience of social communication.
I am not interested in being a role model, or in fulfilling the expectations of others. I know I am of most use to others and to myself by being this unique self: Nature, I have noticed, is not particularly devoted to copies, and human beings needn't be either.
We have accounts of the deification of men in pagan mythology. But I do not remember any account of a god becoming a man, to help man. Whoever heard of Jupiter or Mars or Minerva coming down and attempting to bear the burdens of men? The gods were willing enough to receive the gifts of men, but Christianity is unique in the fact that our God became a man with human infirmity and emptied Himself of the glory of heaven, in order that He might take upon Himself the sins, diseases and weakness of our humanity.
