Is the Holy Spirit the mob mentality of God?

I've just been reading C.S. Lewis's Beyond Personality in which he tries to describe God. He arrives at a necessarily relational, super-personal being consisting of Father and Son co-eternal and of the same substance. So far so good!

He then introduces the idea of the Holy Spirit by way of the 'corporate personality' created by a close community such as a family. In such a close gathering the whole becomes more than the sum of its parts and a kind of personality is produced - a mob mentality! Lewis concludes that for God this corporate personality is infinitely more real than anything cultivated by human communities and actually constitutes a Person - the Holy Spirit.

I really like this idea of the Holy Spirit as God's mob mentality, it totally fits the pattern which seems to pervade Christianity of the unity of parts consistently creating some new and unexpected whole.

The most obvious echo is that of the Church as the 'body of Christ'; as we are individually incorporated into Christ at salvation we become a part not just of a particular interest group or club, not even a slightly odd brand of social activism but a fully functioning (for better or for worse) part of Christ's body, his manifestation in the world and his primary mode of activity. The Church therefore is not merely social or material but its every action and priority is profoundly spiritual, connected to and dependant upon the intimate participation in Christ of every believer. It adds an interesting dimension to daily prayer times.
