Pope Francis today published an Apostolic Letter, given "Motu Proprio," titled "Traditionis Custodes," regarding the celebration of Mass in Latin using the 1962 Missal edited by Pope Saint John XXIII. The Holy Father also wrote a letter to the world's bishops regarding the new document, which came after extensive consultation and rolls back many of the permissions granted by Pope Emeritus Benedict XVI in his 2007 Motu Proprio, "Summorum Pontificum."
