What you'll learn

Key ideas in Mysteries of the Papacy

  • The Latin word 'conclave' literally translates to 'with a key' (cum clave)
  • The practice began in 1271 in Viterbo after cardinals took nearly three years to choose a pope, prompting frustrated locals to lock them in and tear off the roof
  • Cardinals and staff take an absolute vow of secrecy about all proceedings and votes inside the conclave
  • Modern conclaves employ electronic jamming devices and sweeping sweeps in the Sistine Chapel to block eavesdropping
  • Breaching the conclave's secrecy incurs 'latae sententiae' excommunication (automatic expulsion from the Church)
  • Black smoke means a ballot round failed to elect a pope, while white smoke announces a successful election
  • Chemical cartridges are added to burning paper ballots inside the Sistine Chapel stove to produce distinct, reliable color
  • Church bells ring alongside white smoke because smoke colors were historically hard to distinguish against overcast skies
  • A candidate must win a strict two-thirds supermajority of the voting cardinals to become pope
  • The high supermajority requirement ensures that a broad consensus is reached rather than letting a regional or ideological faction force through a candidate with a bare majority
  • A newly chosen pope chooses a new name upon acceptance, setting aside their birth name
  • Papal names serve as a clear signal of the new pontiff's spiritual priorities, tone, and intended institutional direction by invoking predecessors or saints
  • Taking a new name marks a symbolic death of the private individual and the birth of their public papal office
  • The Latin term 'secretum' historically meant 'private' or 'personal' to the Pope, not clandestine or conspiratorial
  • The title indicated that the records were the Pope's personal working property rather than a state archive
  • Centuries of popular fiction and conspiracy theories fixated on the misleading modern word 'secret'
