Conclave Secrets: How a New Pope Is Chosen Behind Closed Doors

The election of a new pope—one of the most sacred and secretive processes in the Roman Catholic Church—is a centuries-old tradition carried out by the College of Cardinals during a process called the conclave. From white smoke to the Latin phrase “Habemus Papam” (“We have a pope”), the world watches with fascination. But how exactly does it work? This article offers a complete overview of the origins, procedures, symbols, and mysteries behind the papal conclave.


1. What Triggers a Papal Conclave?

A papal conclave is held when:

  • A pope dies
  • A pope resigns (as Benedict XVI did in 2013)

Once the Papal See becomes vacant (known as sede vacante), preparations begin immediately for the election of a new pontiff.


2. The Origins of the Conclave

The term “conclave” comes from the Latin cum clave, meaning “with a key”, signifying the cardinals are locked away to deliberate in secret.

  • The first formalized conclave system began in 1274, after long delays in papal elections.
  • Reforms over centuries have shaped today’s highly organized procedure.

3. Who Votes? The College of Cardinals

  • The conclave includes all cardinals under the age of 80.
  • Typically around 120 cardinals are eligible.
  • Most are appointed by previous popes and represent different regions and factions of the Church.

4. The Pre-Conclave: Preparation and Oaths

  • The conclave takes place in Vatican City, mostly in the Sistine Chapel.
  • Cardinals take an oath of secrecy.
  • All forms of communication with the outside world are prohibited—no phones, media, or contact.
  • Lodging is provided at Domus Sanctae Marthae, a Vatican guesthouse.

5. The Voting Process: Ballots and Smoke Signals

Each day, cardinals gather in the Sistine Chapel for up to four rounds of voting (two in the morning, two in the afternoon).

Step-by-step voting procedure:

  1. Ballots are distributed to each cardinal.
  2. They write the name of their chosen candidate, fold the ballot, and place it on a gilded plate before slipping it into a chalice.
  3. Votes are counted and read aloud.
  4. After each round, the ballots are burned in a special stove:
    • Black smoke (fumata nera) = no decision.
    • White smoke (fumata bianca) = a pope has been elected.

6. Majority Rules

  • To be elected, a cardinal must receive a two-thirds majority.
  • If after several days no candidate reaches this, voting rules may be altered, but this rarely happens due to the pressure to reach consensus.

7. Accepting the Office

Once a cardinal receives the necessary votes:

  1. The Dean of the College of Cardinals asks:
    “Do you accept your canonical election as Supreme Pontiff?”
  2. If he accepts, he chooses a papal name—a powerful symbolic act.
  3. He is then dressed in papal white and led to a private room called the “Room of Tears”, where he prepares emotionally and spiritually.

8. The Announcement: Habemus Papam

Shortly after, the cardinal proto-deacon steps onto the balcony of St. Peter’s Basilica and announces to the world:

“Annuntio vobis gaudium magnum: Habemus Papam!”
(“I announce to you a great joy: We have a Pope!”)

The new pope then appears to give his first public blessing, Urbi et Orbi (“to the city and the world”).


9. Symbolism and Tradition

The conclave is steeped in ritual:

  • Cardinals wear scarlet robes to symbolize their willingness to die for the faith.
  • The election occurs under Michelangelo’s “Last Judgment”, a reminder of divine oversight.
  • Silence, prayer, and reflection dominate the process, with daily Masses and meditation.

10. Modern Reforms and Security

Popes like John Paul II and Benedict XVI introduced updates to:

  • Improve logistics and housing
  • Guard against outside influence and leaks
  • Enforce technological surveillance to ensure secrecy

Yet, despite these changes, the conclave remains a sacred mystery, carefully preserving its ancient dignity.


Conclusion: Divine Inspiration and Human Consensus

Though steeped in history and ceremony, the conclave is also a practical matter of politics, theology, and international dynamics. The new pope must be a spiritual leader, a political diplomat, and a symbol of global unity. The election process—both ancient and adaptive—continues to captivate a watching world.
