Editing Pope Pius XII (section)

====Role of theology====
This theological investigative freedom does not, however, extend to all aspects of theology. According to Pius, theologians, employed by the Catholic Church, are assistants, to teach the official teachings of the church and not their own private thoughts. They are free to engage in empirical research, which the church generously supports, but in matters of [[morality]] and religion, they are subjected to the teaching office and authority of the church, the [[Magisterium]]. "The most noble office of theology is to show how a doctrine defined by the Church is contained in the sources of revelation, ... in that sense in which it has been defined by the Church."<ref>Pius XII, Enc. ''Humani generis'', p. 21</ref> The deposit of faith is authentically interpreted not to each of the faithful, not even to theologians, but only to the teaching authority of the Church.<ref>''Humani generis'', p. 21</ref>
