How the Church Recognizes Saints by Jeannine Marino, assistant director in the Office for Evangelization and Catechesis of the U.S. Conference of Catholic Bishops. Marino holds a licentiate in canon law from The Catholic University of America
The process of declaring one a saint in the Catholic Church is called canonization. The canonization process is a canonical (Church law) procedure by which the Church through the Pope solemnly declares a Catholic to be united with God in heaven, an intercessory to God on behalf of the living, and worthy of public and universal veneration.
A cause of canonization examines a person’s life and death to determine if they were either martyred or lived a virtuous life. Every cause of canonization has two phases: the diocesan and Roman phase. The diocese responsible for opening a cause is the diocese in which the person died/was martyred. The diocese, religious order, association or lay person(s) requesting (petitioning) for the cause asks the diocesan bishop, through a person known as the postulator to open an investigation into the martyrdom or life of the person.
