CatholicCulture.org: (CWN) Pope Benedict invokes Mary as ‘Mediatrix of all graces’
February 11, 2013, will be remembered as the day on which Pope Benedict XVI announced that he would resign from the papacy. The day was also the memorial of Our Lady of Lourdes and the 21st World Day of the Sick.
In his Latin-language letter naming Archbishop Zygmunt Zimowski, president of the Pontifical Council for Health Pastoral Care, as his special envoy to the solemn celebration of the World Day of the Sick at the Shrine of Our Lady of Altötting (Germany), Pope Benedict entrusted the prelate’s mission “to the intercession of the Blessed Virgin Mary Immaculate, Mediatrix of all graces” [intercessioni Beatae Virginis Mariae Immaculatae, Mediatricis omnium gratiarum].
Although the Second Vatican Council and numerous popes have invoked the Blessed Virgin as “Mediatrix,” the papal use of the title “Mediatrix of all graces” is far rarer. The phrase occurs most authoritatively in Caritate Christi Compulsi, Pope Pius XI’s 1932 encyclical on the Sacred Heart, and has appeared on a handful of other occasions in documents issued by Pope Benedict XV, Pope Pius XI, Venerable Pius XII, and Blessed John XXIII.
