Fourth-grade students are focusing on the Altar for this year’s PBL on Sacred Space. Fr. David discussed the many types of altars with students and where these will be located within the new Cathedral. The two main altars discussed were the Altar of Sacrifice and the Altar of Reservation. He shared the design of the altars with students and explained the richness of the design. Students also learned about the various relics (from Saints such as John Paul II and Mary Margaret Alacoque) that will be present in the new Cathedral.
