Mother Teresa: Born on August 26, 1910, in Skopje, the following day was baptized as Agnes Gonxha Bojaxhiu
Mother Teresa found her religious calling at the age of 12 going to an annual pilgrimage to the Church of the Black Madonna in Letnice with her local Sacred Heart choir.
On September 10, 1946, Mother Teresa experienced another calling, the "call within a call", riding in a train from Calcutta to the Himalayan foothills for a retreat when she said Christ to her and told her to abandon teaching to work in the slums of Calcutta aiding the city's poorest and sickest people.
Saint Teresa quickly made the somewhat vague calling into concrete actions by making an open-air school and established a home for the dying destitute in a dilapidated building she convinced the city government to donate to her cause.
In February 1965, Pope Paul VI bestowed the Decree of Praise upon the Missionaries of Charity, which prompted Saint Teresa to begin expanding internationally.
After several years of deteriorating health, in which she suffered from heart, lung, and kidney problems, Saint Teresa died on September 5, 1997, at the age 87. She was beatified as "Blessed Teresa of Calcutta" on October 19, 2003 in a ceremony led by Pope John Paul II.
