There is a conference in Rome celebrating the tenth anniversary of Summorum Pontificum from September 14 to September 17. On February 11, 2017, the group which organized this pilgrimage, Coetus Internationalis Summorum Pontificum, described the purpose for this conference as follows:
At the press conference, it was confirmed that, on Thursday, 14 September 2017, there will be a colloquium on the tenth anniversary of the motu proprio at the Pontifical University of Angelicum, during which Archbishop [Guido] Pozzo, among others (their names will be communicated over the coming months), will take stock of these ten years of renewal of the traditional liturgy in the Church.So they are taking "stock of these ten years of renewal of the traditional liturgy." But was "renewal of the traditional liturgy" the reason for Summorum Pontificum? This is certainly not the reason given in the Motu Proprio, which plainly says that, despite the Second Vatican Council's desire "that the respect and reverence due to divine worship should be renewed and adapted to the needs of our time", some in the Church were still holding on to the Traditional Latin Mass. Pope Benedict felt that since the TLM was and always will be holy, there was no reason to withhold this Mass from them.
