SATURDAY MORNING MASS CANCELED!

Due to Cleco needing to turn the power off on the entire campus this Saturday, September 5th, the 8:30am Mass is canceled. The Blessed Sacrament will be reposed at 8:00am. Power should be turned back on in the afternoon, we we will still have 2:00pm Confessions and the evening Masses. Thank you for your patience. —Fr. Dan
