Special prayers have been held at the tomb of Mother Teresa in the Indian city of Calcutta to mark the 10th anniversary of her death.
Mother Teresa won the Nobel Peace Prize in 1979
They were attended by hundreds of people, many of them drawn from some of the city's poorest communities, to whom she had dedicated her life's work.
The Macedonia-born nun suffered a crisis of faith, it was revealed recently.
Despite this, followers insist she should be canonised.
As dawn broke over Calcutta, hundreds of people gathered by her simple tomb at the headquarters of the Missionaries of Charity, the order she founded more than 60 years ago.
They were drawn from all sections of society and also included a sizeable number of international visitors, who paid homage to the woman who was known as the saint of the gutters.
In a special service led by the city's archbishop, Lucas Sirkar, urged the authorities to speed up the process of a canonisation.
"Our expectation is that she be soon declared a saint because she was living as a saint and she lives as a saint in heaven," he said.
"Saints are not only for themselves. Saints are for others, the church and all mankind."
Mother Teresa was beatified in 2003 by Pope John Paul II.
The Pope so admired Mother Teresa that he waived the standard waiting period for beatification to bring forward the honour.
But the recent publication of her letters in which she spoke of being tormented by doubts over her faith has raised concerns that the further process of canonisation could be jeopardised.
