This isn't the first time you've heard the rumour mill chugging along with thoughts about the traditional Latin Mass movement. In this case it is alluding to a possibility of at least some of the SSPX and their affiliated groups coming back to full communion with the Holy See -- or at least making an announcement of such a direction. The source of the rumour seems to be a meeting called in Flavigny, France for tomorrow by the SSPX. It is thought this is perhaps to discuss this possibility. We shall see.
While rumours are always best taken with a dose of healthy skepticism (so as to avoid disappointment at very least), let us also take the matter to prayer; nothing is impossible with God. Let us pray that the rumours would be true for such a development could only be beneficial to the Church Universal and in particular for the new liturgical movement as it would likely allow the greater spread of the classical Roman liturgy which in turn also has a positive effect on the reform of the reform.
