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.
