Pastor bonus (Latin: "The Good Shepherd") is an apostolic constitution promulgated by Pope John Paul II on 28 June 1988. It instituted a number of reforms in the process of running the central government of the Catholic Church. The document's article 1 defines the Roman Curia as dicasteries and institutes supporting the Roman Pontiff "in the exercise of his supreme pastoral office" on behalf of the whole Church, including both the Latin and Eastern Catholic Churches.
