Eucharist: Finding Books

Forty Hours' Devotion, also called Quarant' Ore or written in one word Quarantore, is a Roman Catholic exercise of devotion in which continuous prayer is made for forty hours before the Blessed Sacrament exposed. It commonly occurs in a succession of churches, with one finishing prayers at the same time as the next takes it up. A celebration of such a devotion is begun by a Solemn Mass or "Mass of Exposition", and ended by a "Mass of Deposition".

In the Roman Catholic church, a Eucharistic Congress is a gathering of clergy, religious, and laity to bear witness to the Real Presence of Jesus in the Eucharist, which is an important Roman Catholic doctrine. Congresses bring together people from a wide area, and typically involve large open-air Masses, adoration of the Eucharist (Blessed Sacrament), and other devotional ceremonies held over several days. There are National and International Eucharistic Congresses.
