@Jan Joseph In "Summorum Pontificum" Pope Benedict stated that there could be widespread use of the 1962 Missal. He did not say there could be widespread use of the Tridentine Rite of Mass, because he would have been aware that the Sacred Magesterium of the Church has previously commanded that the Missal of Pope St Pius V MUST be used by every Priest eternally, since it IS the Missal of the Roman Catholic Church and it is THAT Missal that is forever protected by both the Sacred Council of Trent AND the Papal Bull "Quo Primum"
"Quo Primum" states that the Missal promulgated by Pope St Pius AND NO OTHER MUST BE USED BY EVERY PRIEST until the end of time.
When Francis issued HIS recent decree, he ALSO, made no mention of prohibiting the Latin Rite of Mass, (he clearly chose his words carefully as he must know that he has no authority to prohibit it as long as it is said in accordance with the Decree in "Quo Primum") instead he said "No" to the use of the 1962 Missal.
The Sacred Magesterium permits him to withdraw use of the 1962 Missal as it is quite a few pages shorter than the original specified Missal of Pope St Pius V. No-one has any authority to stop any Priest celebrating the Mass according to the Missal of Pope St Pius V. Trent named it Tridentine as it was codified at "Tridentum" which is the Latinised form of saying Trent! According to the text of "Quo Primum" anybody whomsoever that dares to abrogate, prohibit, refuse permission to say etc....the Missal of Pope St Pius V is (according to the text) anathematized (damned, eternally to be burned ie about to receive a just punishment when they find themselves face to face with Our Lord)
PS If Francis disagrees with any of these words - he is anathematized and is clearly a false Shepherd who is promoting and running a new schismatic Church (as the prophecies of Blessed Anne Katherine Emmerich and Marie Julie Jahenny forewarn)!. He will have intentionally forced Priests to disobey a Dogmatic pronouncement of a former Pope, and sought to replace the TRUE Mass of the Church with an invalid Rite, that is not even permitted by Church Law.
