Eucharistic Adoration...this we believe.

Eucharistic adoration is the act of worshiping God as He is present in the consecrated Eucharist. Since the Last Supper, when Jesus broke bread and distributed the wine, saying, "This is My Body" and "This is My Blood," Catholics have believed that the bread and wine are no longer merely baked wheat and fermented grape juice, but the actual living presence of the Second Person of the Trinity. Spending time before the Blessed Sacrament, in prayer and devotion, is exactly the same as spending time before the living God. Adoration occurs whenever someone kneels in front of a tabernacle, that contains the Blessed Sacrament, genuflects toward a tabernacle, bows before receiving the Blessed Sacrament at Mass, or, in a more focused way, when the Blessed Sacrament is exposed for adoration.
Although the Real Presence has been recognized since the time of the apostles, evidence shows perpetual adoration may have begun in the sixth century in the Cathedral of Lugo, Spain. By the twelfth century, St. Thomas a Becket is known to have prayed for King Henry II before the "majesty of the Body of Christ," and by the sixteenth century the devotion known as forty hours had developed. In nineteenth-century France, perpetual adoration developed in communities of contemplative nuns. The devotion eventually spread to parishes throughout the world.
"Of all devotions, that of adoring Jesus in the Blessed Sacrament is the greatest after the sacraments, the one dearest to God and the one most helpful to us."
--St. Alphonsus Ligouri

"Adoration of the Blessed Sacrament is...an important daily practice and becomes an inexhaustible source of holiness...It is pleasant to spend time with (Christ), to lie close to his breast like the Beloved Disciple and to feel the infinite love present in his heart."--Pope John Paul II, The Church and the Eucharist
