The Most Holy Body and Blood of Christ (Catholic)
Also known as Corpus Christi, this is a Solemnity, a feast of the highest rank in the Catholic Church, honoring the Holy Eucharist, bread and wine which is ritually blessed and consumed during mass. Catholics believe this ritual blessing transubstantiates, or changes the substance of the bread and wine, so that it becomes the Real Presence, or body and blood of Jesus Christ. This solemnity places a special emphasis on the Real Presence of the Lord Jesus Christ in the Eucharist. It is celebrated the Sunday after Trinity Sunday.
