Eucharistic adoration is a Eucharistic practice in the Roman Catholic, in which the Blessed Sacrament is adored by the faithful.Adoration is a sign of devotion to and worship of Jesus Christ, who is believed by Catholics to be present Body, Blood, Soul, and Divinity, under the appearance of the consecrated host, that is, sacramental bread. From a theological perspective, the adoration is a form of latria, based on the tenet of the real presence of Christ in the Blessed Sacrament.

Christian meditation performed in the presence of the Eucharist outside Mass is called Eucharistic meditation.When the exposure and adoration of the Eucharist is constant (twenty-four hours a day), it is called perpetual adoration. In a prayer opening the Perpetual chapel in St. Peter’s Basilica, Pope John Paul II prayed for a perpetual adoration chapel in every parish in the world. Pope Benedict XVI instituted perpetual adoration for the laity in each of the five sectors of the diocese of Rome.
