The songleader was responsible for this announcement when I arrived at my new parish. “Please silence or mute your phones before Mass begins.” For Advent, we cut all announcements and went right to the music. I haven’t returned the notice. Parishioners haven’t forgotten any more often (twice) than they did in cycle B.
At Friday’s Mass of Christian Burial at my parish, the funeral director made the announcement three times, once to each section of the church seating.
Sit in the purple chair and render judgment, if you will. Is this a necessary notification? Under which circumstances would you direct it be made?
