The Sacred Congregation for the Propagation of the Faith was established in 1622 due to the realization that the governmental structure of the episcopal structure and the decretal law was not possible.
Episcopal structure and the
Decretal law was government as described in the
New Testament. In this new structure, missionaries would be given orders from Rome, and administrative power would be traded over to those who were titled bishops. The Sacred Congregation for the Propagation of the Faith was left in charge to give faculties to the aforementioned bishops in addition to perfects, who were similar to bishops without the notoriety. ;A congregation for the propagation of the faith On January 6, 1622
Gregory XV erected the Congregation de Propaganda Fide as central and supreme organ for the propagation of the faith to aim at the union of the Orthodox and Protestant Churches and to promote and organize the mission among non-Christians. ;The establishment of a seminary for the training of missionaries The
Pontificio Collegio Urbano de Propaganda Fide ("Pontifical Urban College for the Propagation of the Faith") was established in 1627 by
Pope Urban VIII for the purpose of training missionaries. It was located at the former Palazzo Ferratini at the
Piazza di Spagna. The college prepared students for holy orders, after which they were to return to their homelands as missionaries. In 1641 Urban VIII placed it directly under the Congregation for the Propagation of the Faith. In 1931 the new
Pontifical Urban University opened on the
Janiculum. ;The establishment of a printing press to provide literature for missions The congregation needed to mass-produce literature for their missions so they established their own
printing press four years after their founding in 1626 (New Catholic Encyclopedia 11, 751). The press contributed it literature to the Collegium Urbanum as well as to missionaries traveling cross-country to territories that the
Vatican entrusted them. The press was originally called Polyglotta, and was intended to print Catholic literature in the various native languages that CPF missionaries would encounter. ==Palazzo di Propaganda Fide==
