The Catechism of the Catholic Church states that: "The Eucharistic presence of Christ begins at the moment of the consecration and endures as long as the Eucharistic species subsist."
Since the Middle Ages the practice of Eucharistic adoration, outside Mass, has been encouraged by the popes. The practice of a "daily Holy Hour" of adoration has been encouraged in the Catholic tradition. Mother Teresa of Calcutta had a Holy Hour each day and all members of her Missionaries of Charity followed her example.
"The visit to the Blessed Sacrament is a great treasure of the Catholic faith. It nourishes social love and gives us opportunities for adoration and thanksgiving, for reparation and supplication." - Pope St. John Paul II
Adoration follows morning Mass on Fridays from 10:00 AM - 12:00 PM in the main church
