"Pope Benedict XVI said that when we look upon Christ in the Eucharist 'we enter into the very dynamic of His self-giving.' For that reason, adoration of the Eucharist, exposed to our view in the monstrance, is particularly important for us, and a particularly powerful encounter with the Lord.
I often ask children to imagine walking by the house of the Holy Family in Nazareth. Children who love the Lord might remember that Jesus lives there, and make a gesture of reverence, or say a short prayer. But if we walked by the Lord’s house, and He was out on the porch, and we could look directly at Him, we would stop, and talk to Him, and know that He was hearing us, and talking to us. So it is with adoring Christ in the Eucharist, visible to us in the monstrance. We see Him, and we know that He sees us. We speak to Him, and we know that He hears us. When we adore Christ in the Eucharist, exposed in the monstrance, the Lord engages all of our senses, through the ministry of the Church, to awaken us to the power of encountering him—love made visible."
