Eucharistic congress

In the 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 Catholic doctrine. Congresses bring together people from a wide area, and typically involve large open-air Masses, Eucharistic adoration (Blessed Sacrament), and other devotional ceremonies held over several days. Congresses may both refer to National (varies by country) and International Eucharistic Congresses.

On 28November 1897, Pope Leo XIII proclaimed Saint Paschal Baylón patron of Eucharistic Congresses and Associations. Provided by Wikipedia
