Apostolic Constitution UNIVERSI DOMINICI GREGIS
21st April 2025
Governing the election of a new Pope of Rome. (There are other Popes; the title was first used by the Patriarch of Alexandria.)
Read it in English.
Read it in Latin, the definitive text.
Sede vacante nihil innovetur.
The movie SHOES OF THE FISHERMAN, which Anthony Quinn, gives an excellent depiction of the death of one Pope of Rome and the election of his successor, although using the traditional composition of the College of Cardinals before it was expanded by Paul VI.
