Rosary For Life


The Reverence for Life Ministry will be praying a
Rosary for Life on
Wednesday, September 26th at 6:15 pm in the Church.  Join them as they pray to end the legalization of abortion in our country and pray for the right to life from conception to natural death.

The Rosary for Life will include time in front of the Blessed Sacrament in Adoration as well as Benediction.  Stay after the Rosary for their monthly meeting in North Wing Rooms B & C, across from the Adoration Chapel.  Hope to see you there!

Bottle Cap Collection

Our Confirmation Office is continuing their efforts to collect plastic bottlecaps to be recycled into a bench for outside the doors at St. Mary Immaculate.  You can drop off plastic bottlecaps in the bin outside the Confirmation Office door.  Help us reach our goal of 400 lbs of bottlecaps!
