Vatican City ? Four people, including a 19th-century woman who founded a religious community in Indiana and a Mexican bishop whose body reportedly did not decay after death, will be elevated to sainthood this fall, the Vatican said Saturday.

Pope Benedict XVI announced the Oct. 15 canonization of Mother Theodore Guerin, Bishop Rafael Guizar Valencia and two others during a ceremony in the Apostolic Palace.

Guerin was a French nun who left her homeland in 1840 for the-then frontier state of Indiana, where she founded St. Mary-of-the-Woods College near Terre Haute. This spring, the nun’s order, the Sisters of Providence, said that Benedict XVI had approved a miracle – the regaining of eyesight by an employee at the order’s mother house – attributed to Guerin’s intercession.

Guizar Valencia, who also is being made a saint, was known in life for his piety and kindness to the poor. His body was exhumed in 1950, 12 years after his death, and witnesses said it had not decayed.

Also being canonized are two Italians: Filippo Smaldone, founder of the Salesian order of nuns, known for his work with deaf-mutes; and Rosa Venerini, who founded a religious teaching community.
