Transfiguration
In the Mass, this theme is carried forward in the Elevation of the Host and Chalice. We are invited to recognize Him when the priest says "This is the Lamb of God."
Outside of Mass, Exposition of the Blessed Sacrament in a monstrance invites us to contemplate His glory. During Benediction in 1822, Bordeaux, France, the priest and everyone present saw the face of Jesus in the monstrance in place of the Blessed Host. The image remained about 20 minutes, until Benediction was completed.
The centrality of the tabernacle makes a statement about His place in our lives.
