“Indeed We have not failed in the past, more than once, to use Our authority and to exercise Our zeal in this behalf. It gives Us much pleasure to recall to mind that We have officially approved, and enriched with canonical privileges, not a few institutions and confraternities having for their object the perpetual adoration of the Sacred Host; that We have encouraged the holding of Eucharistic Congresses, the results of which have been as profitable as the attendance at them has been numerous and distinguished; that We have designated as the heavenly patron of these and similar undertakings St. Paschal Baylon, whose devotion to the mystery of the Eucharist was so extraordinary.”  Pope Leo XIII, Mirae Caritates, May 28, 1902
