canonization
Canonization is the process by which a person is officially recognized as a saint by the Catholic Church. This formal declaration typically follows a thorough investigation of the individual's life, virtues, and miracles attributed to them after death. The process can take many years and involves several stages, including beatification, where the person is declared "blessed."
Once canonized, the saint is venerated by the faithful, and their feast day is established in the liturgical calendar. Canonization serves to affirm the individual's exemplary life and encourages others to follow their example of faith and virtue.
