Vatican City (CNN) Mother Teresa, a Catholic nun who devoted her life to helping India's poor, has been declared a saint in a canonization Mass held by Pope Francis in the Vatican. Pope Francis delivered the formula for the canonization of the Albanian-born nun -- known as the "saint of the gutters" -- before huge crowds of pilgrims gathered in St. Peter's Square in Vatican City on Sunday morning. Applause broke out before he completed the formula of canonization, in which he declared "Blessed Teresa of Calcutta to be a saint." India renamed the city of Calcutta to Kolkata in 2001 to match the Bengali pronunciation. But the church uses the spelling of Calcutta in its references to Mother Teresa.The Catholic nun, who died in 1997, devoted her life to helping India's poorHuge crowds from around the world gather in the Vatican to hear Pope Francis
