Saint Philomena was, as believed by her devotees within the Catholic Church, a young virgin martyr whose remains were discovered in 1802 in the Catacombs of Priscilla. Three tiles enclosing the tomb bore an inscription that was taken to indicate that her name (in the Latin of the inscription) was Filumena, the English form of which is Philomena.
The remains were removed to Mugnano del Cardinale in 1805 and became the focus of widespread devotion, with several miracles credited to the saint's intercession, including the healing of Venerable Pauline Jaricot in 1835, which received wide publicity. Saint John Vianney attributed to her intercession the extraordinary cures that others attributed to himself.
The saintly Kuriakose Elias Chavara had a profound understanding of death. His reflections on death were in tune with the theology and spirituality of his times which could very well be seen in the frightening and fearful picture which he shares through his writings. But he optimistically prescribes various means to safely sail across the troubled ocean to reach the Promised Land.
He looks up to Blessed Virgin Mary 'as the strong vessel, strong enough to resist the tempest of the sea, which gives guarantee of safety and protection to passengers' and St. Joseph as 'the sailor who is familiar with the route and who would safely bring the passengers to a safe landing.
