CIC 474 By its union to the divine wisdom in the person of the Word incarnate, Christ enjoyed in his human knowledge the fullness of understanding of the eternal plans he had come to reveal.1 What he admitted to not knowing in this area, he elsewhere declared himself not sent to reveal.2

CIC 574 From the beginning of Jesus’ public ministry, certain Pharisees and partisans of Herod together with priests and scribes agreed together to destroy him.3 Because of certain acts of his expelling demons, forgiving sins, healing on the sabbath day, his novel interpretation of the precepts of the Law regarding purity, and his familiarity with tax collectors and public sinners4 –- some ill-intentioned persons suspected Jesus of demonic possession.5 He is accused of blasphemy and false prophecy, religious crimes which the Law punished with death by stoning.6

CIC 1328 The inexhaustible richness of this sacrament is expressed in the different names we give it. Each name evokes certain aspects of it. It is called:
Eucharist, because it is an action of thanksgiving to God. The Greek words eucharistein7 and eulogein8 recall the Jewish blessings that proclaim – especially during a meal – God’s works: creation, redemption, and sanctification.

CIC 1335 The miracles of the multiplication of the loaves, when the Lord says the blessing, breaks and distributes the loaves through his disciples to feed the multitude, prefigure the superabundance of this unique bread of his Eucharist.9 The sign of water turned into wine at Cana already announces the Hour of Jesus’ glorification. It makes manifest the fulfillment of the wedding feast in the Father’s kingdom, where the faithful will drink the new wine that has become the Blood of Christ.10

CIC 1339 Jesus chose the time of Passover to fulfill what he had announced at Capernaum: giving his disciples his Body and his Blood:
Then came the day of Unleavened Bread, on which the passover lamb had to be sacrificed. So Jesus sent Peter and John, saying, “Go and prepare the passover meal for us, that we may eat it. ..” They went. .. and prepared the passover. And when the hour came, he sat at table, and the apostles with him. And he said to them, “I have earnestly desired to eat this passover with you before I suffer; for I tell you I shall not eat it again until it is fulfilled in the kingdom of God.”... And he took bread, and when he had given thanks he broke it and gave it to them, saying, “This is my body which is given for you. Do this in remembrance of me.” And likewise the cup after supper, saying, “This cup which is poured out for you is the New Covenant in my blood.”11

CIC 1376 The Council of Trent summarizes the Catholic faith by declaring: “Because Christ our Redeemer said that it was truly his body that he was offering under the species of bread, it has always been the conviction of the Church of God, and this holy Council now declares again, that by the consecration of the bread and wine there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord and of the whole substance of the wine into the substance of his blood. This change the holy Catholic Church has fittingly and properly called transubstantiation.”12

CIC 1403 At the Last Supper the Lord himself directed his disciples’ attention toward the fulfillment of the Passover in the kingdom of God: “I tell you I shall not drink again of this fruit of the vine until that day when I drink it new with you in my Father’s kingdom.”13 Whenever the Church celebrates the Eucharist she remembers this promise and turns her gaze “to him who is to come.” In her prayer she calls for his coming: “Marana tha!” “Come, Lord Jesus!”14 “May your grace come and this world pass away!”15
