Pope Benedict lived up to his title of pontifex, or bridge-builder, when he allowed the wider use of the Tridentine rite – more properly the Extraordinary Form of the Mass – in the Apostolic Letter Summorum Pontificum of 2007. There has been 13 years for this concession to advance its stated aim: to foster reconciliation in the heart of the Church. There is no sign it has failed, notwithstanding the inevitable occasional dispute. However, Joseph Shaw from the Latin Mass Society suggests in an article that Pope Francis may be changing his previously positive approach to Summorum Pontificum.
