Manual of Adoration of the Most Blessed Sacrament (full version)
Christian worship in the presence of the Eucharist outside Mass is known as Eucharistic Adoration. It has been regularly practised by such as Peter Julian Eymard, Jean Vianney and Thérèse of Lisieux. When the exposure and adoration of the Eucharist is constant (twenty-four hours each day), it is called perpetual adoration. In a monastery or convent this would be done by the resident monks or nuns. In a parish church it would be done by volunteer parishioners, ever since the 20th century. In a prayer which opened the Perpetual chapel in St. Peter Basilica, Pope John Paul II prayed for a perpetual adoration chapel in each parish in the world. Pope Benedict XVI brought in perpetual adoration for the laity in Rome.
This manual, produced by Benedictine of Conception Abbey in Missouri in 1897 gives a set or prayers appropriate for adoration for the most Blessed Sacrament.
