Mother Teresa was canonized on September42016, when Pope Francis formally declared her a saint during a Mass in St. Peter’s Square. The path to sainthood followed a structured canon-law process that included a diocesan investigation, Vatican review, papal confirmation of a first miracle allowing beatification in 2003, and a second miracle investigation and decree enabling canonization in 2016.

Canonical process overview
Canonization in the Catholic Church requires evidence of a holy life, sustained reputation for holiness, and verified posthumous miracles. The cause for Mother Teresa’s sainthood proceeded through a diocesan investigation, followed by a thorough theological and medical review in Rome. Two miracles attributed to her intercession underwent rigorous scrutiny before papal approval for beatification and later canonization.
Steps from death to sainthood
- Servant of God: initial diocesan phase collecting evidence and witness testimonies.
- Venerable: declaration of heroic virtue by the Pope.
- Blessed (Beatification): requires one verified miracle; Mother Teresa reached this stage in 2003.
- Saint (Canonization): requires a second miracle; completed for Mother Teresa in 2016.
Context and controversies
In recent decades, scholarly and journalistic discussions have examined tensions between admiration for Mother Teresa’s humanitarian work and critiques of her positions and the conditions in some of her institutions. These conversations do not affect the canonical status granted by the Church, which proceeded on the basis of the miracle investigations and evaluative criteria.

Mother Teresa’s journey to sainthood demonstrates how the modern Catholic Church conducts formal recognition of holiness, balancing rigorous investigation with the recognition of widespread, enduring devotion. Her canonization in 2016 reflects both the formal requirements of canon law and the global impact of her decades of charitable service.
