Maria Anna Donati (26 October 1848 - 18 March 1925) was an Italian Roman Catholic nun who had established the Calasanzian Sisters in Florence with the aid of Celestino Zini.
[1] Her profession - alongside four companions on 24 June 1889 - saw her assume the new religious name of "Celestina of the Mother of God" in honor of Zini.
The formal introduction of the cause was on 12 July 1982 in which the Congregation for the Causes of Saints granted their approval to the cause and bestowed upon Donati the posthumous title of Servant of God - the first stage in the process.
The two processes were both ratified on 5 July 1985 and were sent in large boxes to Rome for further investigation in order for the Congregation for the Causes of Saints to commence the so-called "Roman Phase" and begin their own line of research into the cause and into Donati's life and virtues.
Pope Benedict XVI approved a miracle attributed to her direct intercession on 1 June 2007 and thus allowed for her beatification to take place.
The beatification was celebrated in the Basilica di Santa Maria del Fiore in Florence on 30 March 2008; Cardinal José Saraiva Martins presided over it on the behalf of the pontiff.
