I never joined the LMS for many of the same reasons that I have never attended an SSPX Mass: I have never been half so sure of anything as some of the chaps in charge of those organisations seem to be of everything. Latin seemed to be not just a shibboleth, but a fetish. And, as Michael Davies once pointed out, but the LMS never seemed to acknowledge, there really was a need for a reform of the celebration of Liturgical practise at Vatican II: most Catholics only ever attended Low Mass, almost never heard Gregorian Chant, almost never participated in celebration of the Divine Office.
Old Nick must have the equivalent of a satisfied grin on his face at the moment: Williamson has separated any hope that the SSPX might swiftly be reconciled to Rome; the South African Bishops seem to have mangled the introduction of a translation into real English of the Roman Rite (instead of the translation into Trite that we have endured for 40 years); and now the LMS seems singlehandedly to have offered "liberal" "Catholics" a major weapon with which to attack Tradition in England and Wales, just as they were losing the argument.
"O God, who bringest wars to nought and shieldest by Thy power all who hope in Thee, overthrowing those who assail them; help Thy servants who implore Thy mercy; so that the fierce might of their enemies may be brought low, and we may never cease to praise and thank Thee."
