Mary MacKillop was a 19th century nun who was a pioneer of Australia's Catholic school system. Her misunderstandings with Catholic bishops of the time led to her excommunication (which was soon lifted) and later on banishment from the city of Adelaide, among other things.
This never stopped the Melbourne born religious and social worker, from her tireless work in the order she co-founded, the Sisters of St Joseph on behalf of poor and abandoned children. MacKillop lived her concluding years in Sydney, where her burial spot in North Sydney is now a site of pilgrimage, already visited by Paul VI, and John Paul II when he came to the city to beatify her in 1995.
Cardinal George Pell, Archbishop of Sydney said on the weekend however, that it is most unlikely that she will be canonized during the Holy Father's visit, despite the pleas of her many devotees.
