Pope Francis, who served as pontiff from 1936 to 2025, has a complex path to potential sainthood as the process is no longer a mere formality for popes. Historically, most early popes, including St. Peter, were canonized, but over time the criteria have become more stringent. Currently, of the 266 popes, only 80 have been canonized with another 11 beatified, indicating a nuanced process involving years of investigation by the Dicastery for the Causes of Saints. This process demands demonstrated holiness and at least two verified miracles, with the final decision resting with the reigning pope. The timeline from death to sainthood has shortened since John Paul II reduced the waiting period, although exceptions, such as his own expedited canonization, have raised concerns about the adequacy of the process in light of subsequent controversies.

Canonization of popes is not guaranteed; historically, of the first 50 popes, 48 were canonized, but today only 80 of 266 have been recognized as saints, reflecting a more selective process.

The path to sainthood involves multiple steps including being declared 'venerable' after an investigation of the candidate's holiness, followed by beatification, and finally canonization after two verified miracles.

The Dicastery for the Causes of Saints rigorously examines candidates' lives and works, ensuring they meet the necessary criteria of goodness, holiness, and devotion to God.

The average time from death to sainthood historically spanned centuries, but John Paul II shortened this to five years posthumously, although this waiting period can be waived as seen in his own rapid canonization.

John Paul II's canonization was expedited in response to public demand, but a later Vatican report suggesting he ignored sexual abuse allegations led to criticism over the haste of his sainthood.

The current canonization process emphasizes a meticulous and prolonged scrutiny to uphold the sanctity and integrity of sainthood, distinguishing modern candidates from early church practices.

Pope Francis's path to sainthood will depend on a thorough review of his life and potential miracles, amidst evolving church standards and expectations for canonization.
