FrDavid96, speaking of rubrics, how did the practice of keeping the lights off until the Gloria at the Vigil develop? The Sacramentary definitely said, “The lights in the church are turned on” before the Exsultet!. The wording is slightly different in 3rd edition of the Roman Missal. For years we’ve sat in the dark because it’s more dramatic, something that totally leaves out those who need to follow the readings in their missals/missalettes for whatever reason (one candle doesn’t really shed enough light for old eyes to read that small print).
It’s actually rather simple (at least in one way).
Sometimes it’s easy to forget that we did not even have electric lights until relatively recently in human history.
Even though electric lights were invented in 1879, that does not mean they appeared in every church building in the world immediately.
My point here is that any rubric dealing with electric lights is necessarily going to be a modern-day one. I know that sounds obvious, but frankly some people forget that. Until recently, the only lights at the Easter Vigil were candles (admittedly, maybe some scattered oil or gas lamps, maybe in larger or wealthier churches, but not enough to be significant).
It’s difficult to change rubrics for the most important Masses of the year. History proves that. We find the oldest customs retained in the most important Masses such as those of Easter, Holy Week, and Christmas. In part, this is done intentionally. In part, it happens accidentally. People either actively want to retain doing what they have become accustomed to doing, or they simply forget (or don’t notice) changes.
For example, just look at the CAF discussions about Good Friday. The response at the unveiling of the cross is supposed to be “Come let us adore” (since 2011). Yet, some places are still using “Come let us worship.”
I checked the old Sacramentary. The rubric to turn-on the lights is very difficult to find—even though I went looking for it. It’s s simple one line that appears after “Christ our Light” It’s not even printed in red ink and it’s at the very bottom of a page. I’m reading the Catholic Book Publishing Sacramentary which was (by far) the most widely used for that time-period.
