Priests—at least many that I know and have spoken to—do a fair bit of administration. I was blown away with how much “paperwork” and business administration they need to do.
A lot of their time is taken up by the above, and then many here have at least two funerals a week on.
Lack of Sunday Mass attendance is the visible symptom of an strong undercurrent, which is made up of many different aspects.
Honestly, my two local parishes offer 9:30am Italian Masses, one then has a 10:30am Mass in English and the other has a 11am Mass in English. Personally, I wake up before 5am and would love to see a 7am or 8am Sunday morning Mass but that isn’t going to happen. I would have to travel into the CBD to get this.
A lot of the parish activities are also during the working week—like a prayer circle at 10am on a Tuesday. Perhaps moving it to after or before Mass would increase attendance.
Much of what is going on in parishes here is for the retired or SAH-parents.
