Direct Answer: You Do Not Have to Be a Cardinal to Become Pope
Any baptized Catholic male can be elected pope, whether or not he is a cardinal. While most recent popes have been cardinals, it is not a rule or a requirement. The only formal rules are that the pope must be male and baptized into the Catholic Church. In practice, all recent popes have been cardinals because senior church leaders are more likely to be chosen, but canon law does not limit the election to cardinals. The election happens in a papal conclave, where eligible electors vote until one candidate accepts the role.
Who Is Eligible to Be Pope
Canon Law Requirements
Catholic canon law specifies only two requirements for the pope:
- Must be male
- Must be baptized Catholic
There is no requirement that a pope hold episcopal orders or be a cardinal. In theory, a baptized layman could be elected, although no woman can be pope under current discipline. This openness is rooted in canon 332 and the longstanding tradition of male-only holy orders in the Latin Church.
Practical Election Rules
During a conclave, cardinals under the age of 80 serve as electors. They meet in a sealed setting and vote by secret ballot until one candidate receives a two-thirds majority. While cardinals dominate the electorate, the rules do not bar non-cardinals from being proposed or elected, provided they meet the basic requirements. The elected pope must then accept the office for the election to be valid.
Historical Examples of Non-Cardinal Popes
Before modern times, it was not uncommon for laymen or non-cardinals to become pope. The last non-cardinal pope was Adrian VI in 1522, who was a bishop and previously a professor. Since then, nearly every pope has come from the College of Cardinals, reinforcing the pattern without creating a legal rule. These cases show that being a cardinal is common but not compulsory.
Why Most Popes Are Cardinals
Cardinals are senior leaders chosen by the pope to advise and govern. They bring deep administrative, theological, and diplomatic experience. In a conclave, cardinals are already formed in leadership and often hold curial roles, making them familiar candidates. The visibility, governance experience, and age limits (cardinals under 80 can vote) explain why cardinals nearly always emerge as pope, even when a non-cardinal would be technically allowed.
How the Papal Conclave Works
Electors and Voting
Only cardinals under 80 are eligible to vote in a conclave. They gather in the Sistine Chapel and take an oath of secrecy. Voting occurs in morning and afternoon sessions, with ballots burned after each round. If no candidate reaches the required majority, the process repeats until one person accepts election. The identity of the elected pope is revealed by the white smoke from the Sistine Chapel chimney.
Acceptance and Inauguration
Election is not complete until the chosen cardinal accepts the office. Once acceptance is given, the dean or senior cardinal asks for the papal name, the protodeacon announces the new pope on the balcony, and the crowd responds with acclamations. The new pope then appears for blessing and later celebrates his inaugural Mass, marking the formal start of his pontificate.

Key Takeaways
- Any baptized Catholic male can be pope; being a cardinal is not mandatory.
- Cardinals under 80 are the electors, but non-cardinals could legally be elected.
- The conclave relies on secrecy, oath-bound voting, and universal acceptance of the elected candidate.
- Historical precedent shows non-cardinals have served as pope, though it is rare today.
Most popes have been cardinals because of experience and visibility, not because of a formal rule.
Understanding the difference between law, tradition, and practice clarifies why cardinals are nearly always chosen while confirming that canon law does not require it. This enduring design balances continuity, governance experience, and openness to any qualified Catholic man.
For Catholics and observers alike, the election of a pope is both a spiritual discernment process and a governed institutional procedure. The next conclave will proceed under these same rules, regardless of whether the next pope emerges from the College of Cardinals or, in theory, from elsewhere within the eligible male baptized Catholic population.
