Beatification
Catholic Church leaders have praised Charles for putting his Christian faith first in making political decisions, and for his role as a peacemaker during the war, especially after 1917.
The cause or campaign for his canonization began in Vienna in 1949. On 25 April 1951, the cause was transferred to Rome, and Charles was declared "servant of God", the first step in the process. At the beginning of the cause for canonization in 1972 his tomb was opened and his body was discovered to be incorrupt.
On 14 April 2003, the Vatican's Congregation for the Causes of Saints, in the presence of Pope John Paul II, promulgated Charles of Austria's "heroic virtues". Charles thereby acquired the title "venerable". On 21 December 2003, the Congregation certified, on the basis of three expert medical opinions, that a miracle in 1960 occurred through the intercession of Charles. The miracle attributed to Charles was the scientifically inexplicable healing of the Polish-born Brazilian Sister Maria Zita Gradowska of the Daughters of Charity of St. Vincent de Paul. Sister Maria Zita had suffered from pains in her legs since her youth, and later on would suffer from problems with her venous circulation and swellings, for which she was repeatedly treated over the years, but her health issues would not go away for good. In 1957 she became the Mother Superior of Santa Cruz Hospital in Canoinhas, but the pains in her right leg also gradually became worse. By the end of 1960 she was unable to leave her bed. Despite wanting to resign her position as Mother Superior because of this, she was unable to, as there was an insufficient number of sisters.
Around this time, another sister, who was an assistant of Sister Maria Zita, received printed leaflets about the life of Emperor Karl, which included prayers for his beatification. Naturally, Sister Maria Zita was also informed, however, as she did not care much for the Habsburg dynasty, she did not do anything with this information. She told the other sisters that her bedridden state and the coming absence of another sister worried her, and she was again advised to ask for the intercession of the Emperor, but she did not plan on doing so. That evening however, when lying in bed, she was unable to sleep because of the excruciating pain in her right leg. It is then that she decided to say a prayer of intercession and promised to start the next day with a novena to beg for the grace of beatification for the Servant of God. After praying, she did not feel the pain anymore and was able to easily fall asleep. From then on she was able to resume her duties as Mother Superior and would not suffer from any health problems with her legs for the rest of her life.
Pope John Paul II declared Charles "Blessed" in a beatification ceremony in St. Peter's Square on 3 October 2004. The Pope also declared 21 October, the date of Charles's marriage in 1911 to Princess Zita, to be Charles's feast day. At the ceremony, the Pope stated:The decisive task of Christians consists in seeking, recognizing and following God's will in all things. The Christian statesman, Charles of Austria, confronted this challenge every day. To his eyes, war appeared as "something appalling". Amid the tumult of the First World War, he strove to promote the peace initiative of my Predecessor, Benedict XV.
The main points of Pope Benedict XV's peace plan were: (1) the moral force of right ... be substituted for the material force of arms, (2) there must be simultaneous and reciprocal diminution of armaments, (3) a mechanism for international arbitration must be established, (4) true liberty and common rights over the sea should exist, (5) there should be a renunciation of war indemnities, (6) occupied territories should be evacuated, and (7) there should be an examination of rival claims. The best outcome to the war, according to Pope Benedict XV, was an immediate restoration of the status quo without reparations or any form of forced demands. Although the plan seemed unattainable due to the severity of the war thus far, it appealed to Charles, perhaps as a way to fulfill and preserve his role as Catholic Emperor of Austria and Apostolic King of Hungary. The beatification nevertheless raised controversy over the mistaken claim that Charles authorised the use of poison gas by the Austro-Hungarian Army during World War I. The Emperor actually forbade its use.
Pope John Paul II, who was born Karol Józef Wojtyła in Wadowice (then part of Austrian Poland), was named after Karl. During a private audience with Archduke Rudolf (Karl's son), his sons and their families and Empress Zita (whom the Pope addressed as "his Empress" and bowed his head before) he told them the following:
Do you know why I was named Charles at baptism? Because my father had great admiration for Emperor Charles I, of whom he was a soldier.
From the beginning, Emperor Charles conceived of his office as a holy service to his people. His chief concern was to follow the Christian vocation to holiness also in his political actions. For this reason, his thoughts turned to social assistance.
On 31 January 2008, after a 16-month investigation, a Church tribunal recognized a second miracle attributed to Charles I. A "devout Baptist" from Orlando, Florida was allegedly cured after several recent converts to Roman Catholicism in Louisiana prayed for Charles's intercession.
In 2011, the League of Prayers for the promotion of Charles's cause set up a website, and Cardinal Christoph Schönborn of Vienna has sponsored the cause. One of Charles's granddaughters, Princess Maria-Anna Galitzine, has been a prominent figure in the campaign for sainthood.
