Wednesday, Friday, and Saturday, September 21, 23, and 24, are the fall Ember Days this week. These are days of prayer and penance celebrated seasonly in the Catholic Church. These days, you'll only find them in TLM communities and the Ordinariate. Here's a good reference article: https://www.fisheaters.com/emberdays.html.
The Saturday evening vigil Mass will be a teaching Mass - fully-valid, punctuated by catechetical points. It will be likely around 90 minutes. Sunday Masses per the published schedule, with the parish finance council meeting after the 11 am Mass.
Reminder that CCD / Religious Education begins this Sunday, September 11, between the Sunday morning Masses. Children's classes will run 9:50-10:50. Adults will have a shorter class that fits into that window, and allows for parents to pick up their children when classes finish.
