Pastor aeternus ("First Dogmatic Constitution on the Church of Christ") was issued by the First Vatican Council, July 18, 1870. The document defines four doctrines of the Catholic faith: the apostolic primacy conferred on Peter, the perpetuity of the Petrine Primacy in the Roman pontiffs, the definition of the papal primacy as a papal supremacy, and Papal infallibility – infallible teaching authority (magisterium) of the Pope.[1]
