Mother Teresa Will Be Made a Saint

The Vatican said the Pontiff signed off on the second miracle on Thursday. Mother Teresa was beatified in 2003 as Blessed Teresa of Calcutta for healing a woman’s tumor through divine intervention, but two miracles are required for sainthood. The second miracle, which Pope Francis decreed Thursday, involved curing a man of a viral brain infection.

Mother Teresa, who died in 1997 at age 87, was a beloved missionary whose work led to numerous awards and honors, including the Nobel Peace Prize in 1979.
