By Gretchen Filz, The Catholic Company - The Solemnity of the Most Holy Body and Blood of Christ, historically known by its Latin name, Corpus Christi, celebrates the Real Presence of Jesus Christ in the Holy Eucharist—Body, Blood, Soul, and Divinity. It is traditionally celebrated on the Thursday following the Solemnity of the Holy Trinity. The feast dates to the Middle Ages and originated with a visionary nun and a Eucharistic miracle.
