Mother Teresa, a catholic nun who died in 1997 after devoting most of her life to helping the poor in India, was declared a saint by Pope Francis on Sunday, September 4.
Pope Francis officially canonized Saint Teresa of Calcutta, as she will now be called, during a mass at the Vatican attended by tens of thousands of people, including 1500 homeless people who were bussed in and given seats inside the church.
Canonization is the act of declaring someone a saint, which is done very rarely. The pope did so because two miracles were attributed to Mother Teresa after her death — the disappearance of stomach tumor in an Indian woman and multiple brain tumors in a Brazilian man. Both patients said they were cured after they or loved ones prayed to Mother Teresa.
Mother Teresa became a saint exactly one day before the 19th anniversary of her death.
