There are true vigil Masses, like the Easter vigil, but that is a very different idea than being able to fulfill one's Sunday obligation on Saturday and then sleep in and watch TV or leisurely read the newspaper on Sunday morning.
This has been followed by the steady removal of Holy Days of Obligation or their shifting to days convenient for secular purposes. In short, it was a complete surrender of sacred time and the space that such time preserved in human life.
I think it is also a manifestation of less focus and belief in the supernatural. Perhaps that trend will see a reversal with the fruit of Summorum Pontificum.
I hope so. I live in Florida, btw, where the Saturday “vigil mass” is celebrated at 3:00 pm. I think that may be the earliest they can celebrate it. It has NO connection with Sunday for people - it’s simply doing a weekly obligation of some sort.
