While riding a train to Darjeeling, Sister Teresa Bojaxhiu of the Loreto Sisters' Convent hears the call of God, directing her "to leave the convent and help the poor while living among them".
We know this woman today as Mother Teresa, or Blessed Teresa of Calcutta. She acquired the title “Blessed” after her beatification by Pope John Paul II in 2003. Beatification means that the Catholic Church has accepted documented evidence of her performing one miracle.
She will be canonized, and become Saint Teresa of Calcutta, if and when documentation of a second miracle is established.
