Madame Elisabeth died in the odor of holiness. According to Madame de Genlis, a scent of roses spread across the Place de la Concorde after her execution. In 1953, Pope Pius XII recognized by decree the heroic character of her virtues simply because of her martyrdom. The princess was declared a Servant of God and the cause of beatification was officially presented on December 23, 1953 by Cardinal Maurice Feltin, Archbishop of Paris. In 2016, Cardinal André Vingt-Trois, Archbishop of Paris, reactivated the cause of his beatification. Father Xavier Snoëk, pastor of the parish of Sainte-Élisabeth-de-Hungary, was appointed postulator of the cause (church located in the old Temple district where the princess was imprisoned), and in May 2017 he recognized the association of the faithful promoters of their cause. On November 15, 2017, Cardinal Vingt-Trois, after consulting with the French Bishops' Conference and the nihil obstat of the Congregation for the Causes of Saints in Rome, hopes that the process will lead to the canonization of Madame Elisabeth , sister of Louis XVI.
