At the Second Vatican Council's Dogmatic Constitution on the Church "Lumen gentium", the Roman Catholic Church's teaching on the authority of the pope, bishops and councils was further elaborated. The post-conciliar position of the Apostolic See did not deny any of the previous doctrines of papal infallibility or papal primacy; rather, it shifted emphasis from structural and organizational authority to doctrinal teaching authority (also known as the "magisterium"). Papal "magisterium", i.e. papal teaching authority, was defined in "lumen gentium" No. 25 and later codified in the 1983 revision of Canon Law.
