May Crowning May 9 and 10 during Mother’s Day Masses

Traditionally dedicated to Our Blessed Lady, the month of May is a time of special honor for the Queen of Heaven. May is a time when all creation seems to burst forth in exquisite and vibrant colors. It is the season when nature herself points to the splendor of God’s goodness and beauty. On May 9 & 10 we will honor our Heavenly Mother with a May Crowing at all weekend Masses. With thankfulness to the Lord for the great gift of motherhood, we will also give all mothers a special Mother’s Day Blessing.
