Pope Francis celebrated his birthday (December 17) by giving final clearance for Mother Teresa of Calcutta to become an official saint. Francis declared that the inexplicable recovery of a Brazilian man from a coma in 2008 was due to the nun’s intercession, making it her second miracle. Catholic Church protocols for sainthood generally require evidence that a person lived a virtuous and holy life, and the attribution of two miracles. Experts expect Mother Teresa to be canonized in September.
