Mother Teresa won the Nobel Peace Prize in 1979.
She has been credited with two miracles that paved the path to sainthood. Both involved the healing of the sick, Reuters reported.
Mother Teresa was beatified, or recognized as entering heaven, in 2003 by Pope John Paul II. Teresa answered a woman's prayers to cure a brain tumor, USA Today reported.
Late last year, Pope Francis attributed her second miracle when a Brazilian man with multiple brain abscesses was cured.
Pope Francis met Mother Teresa more than 20 years ago when he was Archbishop Jorge Mario Bergoglio in Argentina, USA Today reported.
Mother Teresa passed away in 1997.
