Feast of Corpus Christi

The Solemnity of the Most Holy Body and Blood of Christ, commonly known as Corpus Christi, is one of the most important and heartfelt solemnities of the Catholic Church’s liturgical year, celebrated on the Thursday following the Solemnity of the Holy Trinity or, in some countries, including Italy, on Sunday. The solemnity was established in 1264 in Orvieto, by Pope Urban IV, with the bull Transiturus.
