This feast is celebrated to solemnly commemorate the Institution of the Holy Eucharist on the first Holy Thursday.
It used to be celebrated on the Thursday following Trinity Sunday, but is now celebrated on the Sunday following Trinity Sunday.
Saint Juliana of Mount Cornillon had a great veneration for the Blessed Sacrament, and longed for a special feast in its honour.
She passed her ideas on to several people of influence including Robert de Thorete then Bishop of Liege,and to Jacques Pantaleon, later to become Pope Urban IV
In 1246 the Bishop ordered the celebration to be held in the following year. In 1264, Pope Urban IV, who had always had great affection for the feast, published the Bull "Transiturus" in which he ordered the annual celebration of the feast of "Corpus Christi". This office, composed by St Thomas Aquinas is one of the most beautiful in the Roman Breviary.Return to Annual Calendar
