Feast Day of The Blessed Virgin Mary, Mother of the ChurchMemorial
From the United States Catholic Conference of Bishops:
"On February 11, 2018, the Congregation for Divine Worship and the Discipline of the Sacraments inscribed a new obligatory Memorial of the Blessed Virgin Mary, Mother of the Church, into the General Roman Calendar. This memorial is celebrated every year on the Monday after Pentecost."
The next excerpt is from the Address of Pope Saint Paul VI, at the conclusion of the third session of the most holy Second Vatican Council
(November 21, 1964: AAS 56 , 1015-1016)
"Taking into consideration the close ties by which Mary and the Church are bound together, to the glory of the Blessed Virgin and for our consolation, We declare Mary Most Holy to be Mother of the Church, that is, of the whole Christian people, faithful and Pastors alike, who invoke her as their most loving Mother; and We establish that by this sweetest of names the whole Christian people should henceforth give still greater honor to the Mother of God and offer her their supplications."
Mary, Mother of the Church, pray for us.
