Mother Teresa of Calcutta is to be made a saint next September
The news broke after it emerged that Pope Francis has officially recognised a second miracle attributed to her.
Mother Teresa, who died in 1997, founded of the Missionaries of Charity and was beatified by Pope John Paul II in 2003.
She is now expected to be canonised in Rome on 4 September.
The announcement came after a private meeting between Pope Francis and Cardinal Angelo Amato, prefect of the Congregation for the Causes of Saints.
The first miracle attributed to her was approved by Pope John Paul II in 2003 and involved curing an Indian woman suffering from an abdominal tumour.
The second miracle attributed to her, approved by Pope Francise, involved the healing of a Brazilian man with several brain tumours in 2008.
Cardinal Amato suggested 4 September as it is the day before Mother Teresa’s birthday.
Blessed Teresa of Calcutta was born Agnes Gonxha Bojaxhiu on 26 August 1910, in Macedonia.
She joined the Sisters of Loretto at 17 and was sent to Calcutta, in India, where she caught TB and was sent to recover in Darjeeling.
While travelling she had an epiphany in which, she said, God told her to leave the convent and live among the poor.
In 1950 she founded the Missionaries of Charity, which helps cares for the sick and poor, with a single house.
It has since grown to comprise some 500 houses around the world.
Mother Teresa won a Nobel Peace Prize in 1979 for her work among the poor in the slums of Calcutta.
