Jeffrey A. Tucker of the splendid Chant Cafe points out something so obvious it's no wonder that many of us have failed to notice it: the Mass celebrated on Saturday evenings (or afternoons) should not be called a "vigil" Mass. True vigil Masses are celebrated before Easter and the Feast of St. John the Baptist; most Sunday Masses celebrated on Saturday are more accurately referred to as "anticipated" Masses (which hardly trips off the tongue but neither does "Extraordinary Form"--whaddya gonna do?).
The anticipated Mass (there now, that wasn't so hard, was it?) is a creature of the post-Vatican II reforms and for once this hidebound conservative has little cause for complaint--in principle, mind you. I recall my in my youth first observing the then-odd sight of worshipers filing into our neighborhood Catholic church on Saturday. I also recall my younger brother and I, who as budding Episcopalians naturally were being carefully (if subtly) taught the myriad joys of anti-Catholicism, gleefully dubbing the service the "Get It Over With Mass" (obviously a case of envy projection). Later on, of course, I learned attendance at Sunday Mass was obligatory for Catholics and to that end Holy Church took efforts to make fulfillment as convenient as possible. That seemed reasonable to me, even if the Mass were to be celebrated the evening before.
As a Catholic, my only real objection to the Get It Over With Mass is, for reasons I do not know (but I'll bet Novus Ordo bears at least partial culpability), it has become the repository for some of the most egregious abuses in modern Catholic worship: for clergy, sloppy, even slovenly, liturgy; for laity, arriving late, wearing dress tank tops and chattering non-stop throughout. Part of the reform of the putative reform, which steadily continues its course albeit at a glacial pace, is for traditionalist Catholics to be ever-vigilant (if you'll pardon the expression) to these abuses and lovingly shaming the perpetrators thereof into larnin' to behave.
