A priest is a man vowed, trained, and consecrated, a man belonging to a special corps, and necessarily with an intense esprit de corps. He has given up his life to his temple and his god. This is a very excellent thing for the internal vigour of his own priesthood, his own temple. He lives and dies for the honour of his particular god. But in the next town or village is another temple with another god. It is his constant preoccupation to keep his people from that god. Religious cults and priesthoods are sectarian by nature; they will convert, they will overcome, but they will never coalesce.

Some force not himself impels him, and he must go.
