Who is The ascetic priest from On the Genealogy of Morals and what is their importance?

The ascetic priest is the embodiment of an ascetic ideal in Nietzsche's philosophy. Development of the ascetic priest is a first step to resolve the question of meaning in the ascetic ideal. A priest's faith, will, power, interest and existence is unified in an ascetic ideal. Despite commitment to the ideal, a priest may not be a happy champion of the ascetic ideal. He is not an objective critic or judge of it. Nietzsche purports to help the priest defend the ascetic ideal. Human life from the view of an ascetic priest is a bridge to another existence.
