The sainthood of Mother Teresa "is a memorable and proud moment", Prime Minister Narendra Modi said on Sunday.
The Pope on Sunday declared Mother Teresa as Saint Teresa at an event in Vatican City.
Earlier, on August 28, Modi paid tributes to Mother Teresa, saying every Indian must feel proud that she was going to be recognised as a saint.
Modi said that despite not being an Indian, Mother Teresa dedicated her whole life serving the Indians.
"Mother Teresa devoted her whole life serving the poor and destitute people in India.
When such a person is conferred with sainthood, it is natural for Indians to feel proud, " Modi said in his radio address.
