And neither do the bishops, who have the temerity to say. it was your heads or mine, and then cancel the Traditional Mass.
Jean Guitton (friend of Paul VI): “The intention of Pope Paul VI with regard to what is commonly called the Mass, was to reform the Catholic Liturgy in such a way that it should almost coincide with the Protestant liturgy. ... There was with Pope Paul VI an ecumenical intention to remove, or at least to correct, or at least to relax, what was too Catholic in the traditional sense, in the Mass and, I repeat, to get the Catholic Mass closer to the Calvinist mass” [Chiron, Yves, François-Georges Dreyfus, and Jean Guitton. Entretien Sur Paul VI. Niherne: Nivoit, 2011. p. 28].

@P. O'B Marcel Lefevre was (automatically) excommunicated because he ordained bishops without permission of the pope. Has nothing to do with liturgy.
Technically true, but the SSPX movement certainly had everything to do with the liturgy. And the 1988 excommunication occurred at the end of years of disagreement. Lefebvre was called to what turned out to be a kangaroo court in Rome as early as 1974. One "saint" let Lefebvre be squashed and another "saint" could have prevented that excommunication. By the way, I am not an SSPX attendee.
@P. O'B I watched a programme on EWTN about 15 years ago. It was a documentary about a Traditional Benedictine Monastery in the North of France. The Monastery disclosed that Paul VI had visited the Order and had pleaded with them to continue celebrating the Latin Mass. It was inferred that Paul VI had made the same request to many other Benedictine Monasteries also. So the circumstances of the Liturgy being altered might not as we are led to believe. For that reason, it's probably best to reserve Judgement.
And Paul VI did just that and has been canonized. Go figure. And Marcel Lefebvre denied that he had that power and was excommunicated. Again, go figure.
