While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, "Take it; this is my body."Then he took the cup, gave thanks and offered it to them, and they all drank from it.
"This is my blood of the covenant, which is poured out for many," he said to them. "I tell you the truth, I will not drink again of the fruit of the vine until that day when I drink it anew in the kingdom of God." (Mk 14,22-25)
A final mystery of light is the institution of the Eucharist, in which Christ offers his body and blood as food under the signs of bread and wine, and testifies “to the end” his love for humanity (Jn 13:1), for whose salvation he will offer himself in sacrifice.
