Since there were many miraculous aspects about Luisa, and Jesus’ messages as she recorded in her diary were too eloquent to come from someone as poorly educated as herself, the Church took an interest in Luisa’s work early on. Throughout the years she wrote, Luisa was assigned priest confessors to guide her, ensuring she was neither delusional nor being misled by the devil. St. Annibale Maria Di Francia was her priest confessor for 17 years, until he died on June 1, 1927. A passionate proponent of Luisa’s writings, he placed the Nihil Obstat on the first 18 volumes he supervised until his death, and the Archbishop Leo of Trani granted his Imprimatur soon after. On November 13, 1995, then Cardinal Ratzinger, Prefect of Congregation for the Doctrine of Faith, approved the release of the 34 manuscript copies of Luisa’s diary for private study, in aid of her canonization process.
On November 1948 Archbishop Addazi of Trani grants Luisa the title “Servant of God”. On February 1994 Archbishop Cassati opens the Cause of Beatification with the Vatican’s Congregation of Saints’ Causes and in March 2004 the Vatican officially opens the Cause for Luisa’s Beatification and Canonization. Then in 2015, on the occasion of her 150th birthday, Vatican Publishing releases Luisa’s official biography – The Sun of My Will.
