Article 66 - Sacred Office
Canon 3901 (link)
When a man or a woman is finally accepted by a Religion or Cult to a position of Minister, a formal ritual is usually associated which involves the ordination or consecration of the candidates for office. During this process, the dogma of the particular Religion or Cult recognizes a conveyance of power and authority to the candidate and a believed change in their person.
Canon 3902 (link)
Some Religions and Cults believe that so powerful and sacred is a Sacred Office that once invested or consecrated, the Office cannot be removed, except under extreme circumstance.
