Solemnity Feast of Corpus Christi, the Body and Blood of Christ
As they were eating, He took bread, and blessed, and broke it, and gave it to them, and said, "Take; this is My Body." And He took a cup, and when He had given thanks He gave it to them, and they all drank of it. And He said to them, "This is My Blood of the covenant, which is poured out for many. Truly, I say to you, I shall not drink again of the fruit of the vine until that day when I drink it new in the kingdom of God."
Mark 14: 22 - 24
