To show reverence toward someone means to have great awe or respect for that person. This particular virtue reminds us of God's greatness - the majesty, splendor, and glory of God that makes Him alone worthy of our complete adoration and worship. When we reflect on the perfect holiness of God - and, by extension, the holiness that He bestows on the Blessed Mother, the angels, saints, and all persons, places, and objects dedicated to Him - the virtue of reverence seems the most appropriate response: "Holy, holy, holy is the Lord, God of Hosts!" (Isaiah 6:3)
