What is the significance of the decanonized saints list in the history of the Catholic Church?

The decanonized saints list is significant in Catholic Church history because it represents a shift in the Church's understanding of who should be officially recognized as a saint. This list includes individuals who were previously recognized as saints but were later removed from official veneration. This decision reflects the Church's evolving criteria for canonization and its willingness to reevaluate the lives and actions of past saints.
