Iconic missionary nun Mother Teresa of Calcutta will be officially elevated to Catholic sainthood during a September 4 Mass in St Peter's Square led by Pope Francis, the Vatican confirmed Friday.
The information came from a statement listing Francis' engagements from June to September.
The date for Teresa's so-called canonization Mass was already known, but not its location. There were suggestions that it could have been celebrated in her adopted Indian city of Kolkata, previously known as Calcutta.
The Mass falls on the eve of Teresa's feast day, which marks the anniversary of her death at the age of 87 on September 5, 1997.
Born Agnes Gonxha Bojaxhiu in 1910, in Skopje, Macedonia, the ethnic Albanian Teresa took Indian citizenship. She founded the Missionaries of Charity in 1950 and gained worldwide recognition for her work, including a Nobel Peace Prize in 1979.
Teresa is a revered figure throughout the world, and her path to sainthood has been very speedy. In modern times, only John Paul II made the grade quicker, having been canonized in 2014, nine years after his death.
