Blessed Mother Teresa of Kolkata, soon to be a saint, is such a world figure, she needs no introduction. Born Agnes Gonxha Bojaxhiu of Albanian parents on August 26, 1910, in Skopje, in what is Macedonia today, Mother Teresa came to eastern India’s Kolkata city, formerly Calcutta, in 1929, as a missionary nun. Affectionately known as the "saint of the gutter" for her unconditional love for the poor and the abandoned, she founded her Missionaries of Charity congregation in 1950. She earned numerous national as well as international honours for her works of mercy, including the Nobel Peace Prize in 1979. She died on September 5, 1997 at the age of 87 and St. John Paul II declared her Blessed in the Vatican, on October 19, 2003. And now Pope Francis will declare her a saint on Sept. 4 at a ceremony here in Rome’s St. Peter’s Square. To know about the preparations taking place in Mother Teresa’s adopted hometown of Kolkata for this great day, we talked on the phone with Archbishop Thomas D’Souza of Calcutta. He first explained the significance of this canonization for his city.
