Mary, the Help of Christians (Latin: Sancta Maria Auxiliatricis Christianorum), is a Roman Catholic title of the Blessed Virgin Mary, based on a religious devotion now associated with a feast day of the General Roman Calendar on 24 May. The Catholic saint, John Chrysostom, was the first person to use this Marian title in year 345 AD. Both Don Bosco and Maria Domenica Mazzarello also propagated the same piety and devotion. Pope Pius V invoked the Christian army of the Holy League in 1571 and its victory achieved was consequently attributed to the intercession of Mary under this devotional title during the expansion of the Islamic Ottoman Empire intended to invade Christian Europe. Pope Pius IX granted the first decree of pontifical coronation to the venerated Marian image enshrined within the Basilique Notre-Dame de Bonsecours on 15 July 1870. The former Archbishop of Rouen, Cardinal Henri-Marie-Gaston Boisnormand de Bonnechose executed the rite of coronation on 24 May 1880. Pope Leo XIII consequently signed and granted a pontifical decree of canonical coronation towards the Turin image on 13 February 1903. The rite of coronation was executed on 17 May 1903 by the former Archbishop of Turin, Cardinal Agostino Richelmy. Pope Pius X raised the namesake shrine to the status of Minor Basilica via his Pontifical decree Anno Reparatæ Salutis on 12 July 1911. The title is also venerated by the Society of Mary (Anglican) who belong to the Church of England. Source: Wikipedia (en)
