I have a more extensive post on the Rorate Mass with a photo from a European parish, with some links. It is done entirely under candle-power, and no lights.
We were attempting to pull together a Tridentine Rorate Mass, but this would have needed to take place early in the morning. Fr. Perrone had given his permission, but in the old calendar, and with it's classes of liturgies, we would not have been able to do so until December 15th, the day EWTN will also hold a Rorate Mass. We then realized that this falls during a mission being offered by the Priests of Opus Angelorum at Assumption Grotto and many would be coming at 8:30am to start a somewhat long day and we assumed a lower turnout than we would have otherwise. Perhaps next year.
In other news: Opus Angelorum Mission
Fr. Wolfgang and Fr. Matthew of Opus Angelorum will be preaching a mission on the Confraternity of the Holy Guardian Angels on December 14 & 15 for those making their consecration to the Guardian Angel and also for new members. Please see the bulletin boards in the church and school for the schedule.
Te Deum Laudamus! Home
