Remember Your Loved Ones

All of the Masses in November will be said for All Souls. The All Souls envelopes will be in the back of the church and in the pews. Don’t miss this wonderful opportunity to remember your loved ones! Write the name of your deceased loved ones on the All Souls envelope and place it in the collection basket during Mass. All of the envelopes will be placed on the altar for the whole month of November.

2020 Collection Envelopes

The new 2020 collection envelopes are ready for pick up in the Parish Hall after all the Sunday Masses or during Parish Office hours. The envelopes are arranged by numerical order. If you do not remember your number an alphabetical list by last name will be on each table. If you do not use your collection envelopes please contact the Parish Office so that we can assign your number to someone else. You can still remain registered by last name even if you do not have an envelope number.
