Yes, we know, Father Lombardi confirmed: the Fraternity's (FSSPX/SSPX - Society's) ordinations are "illegitimate", its priests "do not exercise legitimate ministry". Yes, we know that loving and caring ambiguities, long used in any reference to non-Catholics or non-Christians suddenly disappear when certain "groups" are mentioned - one cannot but cheer the sudden and temporary return to "pre-Conciliar" terseness, certainty, and proclamation of authority.
Which is why we are absolutely certain that, in the past 50 years, absolutely no act of anyone who cannot exercise "legitimate ministry" within the Catholic Church, including Protestant, Eastern Orthodox, or Old-Catholic "ministers", has been allowed in any property in the possession of the Diocese of Ghent, Flanders (Belgium) - the Diocese would not act so inconsistently when first allowing, out of common courtesy, then denying the celebration of a First Mass/New Mass by a new priest of the Priestly Fraternity of Saint Pius X (FSSPX / SSPX), Father Matthias De Clercq, in the parish church of Merelbeke, in his native region (source: Mysterium Fidei - in Dutch).
Further south, in the Diocese of Clermont-Ferrand, in the Auvergne (France), in a ceremony at the brand new Grand Mosque of Clermont-Ferrand, "the Muslim community returned the keys to the Chapel located at rue Sainte Claire, facing the church of Saint-Eutrope, that had been placed at their disposal since 1977 by Bishop Dardel and the Congregation of the Sisters of Saint Joseph. ... The Muslims expressed their gratitude for having been given a place of worship in the city, not having at the time the means to finance one. The Grand Mosque of Clermont was built afterwards... and has been open to the faithful since early 2010." [Source: Diocese, via Perepiscopus.]
