Christ’s blood reveals to man that his greatness, and therefore his vocation, consists in the sincere gift of self. Precisely because it is poured out as the gift of life, the blood of Christ is no longer a sign of death, of definitive separation from the brethren, but the instrument of a communion which is richness of life for all. Whoever in the Sacrament of the Eucharist drinks this blood and abides in Jesus is drawn into the dynamism of his love and gift of life, in order to bring to its fullness the original vocation to love which belongs to everyone…. It is from the blood of Christ that all draw the strength to commit themselves to promoting life. It is precisely this blood that is the most powerful source of hope, indeed it is the foundation of the absolute certitude that in God’s plan life will be victorious.
Saint Pope John Paul II, The Gospel of Life
John the Beloved watches as the body of Christ is elevated on the Cross. He remembers the words of the Master as He elevated the unleavened bread: “This is my body… do this in memory of me.” The Supreme Teacher does not want us to forget that love is self-offering, and so the meal He asks us to share, again and again until the end of time, takes the very shape of His sacrifice.
