In Catholic tradition, bilocation is the reported phenomenon where a saint or holy person appears to be in two places at the same time. It is considered a mystical event and is not formally defined as a doctrine of the Church. Several saints are associated with claims of bilocation, including Saint Padre Pio and Saint Alphonsus Liguori. These accounts usually describe the saint being physically present in one location while simultaneously seen elsewhere performing acts of prayer, ministry, or assistance.
