Thank you for the response and I am assuming this the Catholic position is based in part by John 6; is that a correct assumption? Thanks again for the post.

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.**158 **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.

The first announcement of the Eucharist divided the disciples, just as the announcement of the Passion scandalized them: “This is a hard saying; who can listen to it?”**160 **The Eucharist and the Cross are stumbling blocks. It is the same mystery and it never ceases to be an occasion of division. “Will you also go away?”:
161 the Lord’s question echoes through the ages, as a loving invitation to discover that only he has "the words of eternal life"
162 and that to receive in faith the gift of his Eucharist is to receive the Lord himself.
The institution of the Eucharist****
1337
The Lord, having loved those who were his own, loved them to the end. Knowing that the hour had come to leave this world and return to the Father, in the course of a meal he washed their feet and gave them the commandment of love.
163 In order to leave them a pledge of this love, in order never to depart from his own and to make them sharers in his Passover, he instituted the Eucharist as the memorial of his death and Resurrection, and commanded his apostles to celebrate it until his return; "thereby he constituted them priests of the New Testament."
164
1338
The three synoptic Gospels and St. Paul have handed on to us the account of the institution of the Eucharist; St. John, for his part, reports the words of Jesus in the synagogue of Capernaum that prepare for the institution of the Eucharist: Christ calls himself the bread of life, come down from heaven.

1339
Jesus chose the time of Passover to fulfill what he had announced at Capernaum: giving his disciples his Body and his Blood:
Code:
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."**166**
1340
By celebrating the Last Supper with his apostles in the course of the Passover meal, Jesus gave the Jewish Passover its definitive meaning. Jesus’ passing over to his father by his death and Resurrection, the new Passover, is anticipated in the Supper and celebrated in the Eucharist, which fulfills the Jewish Passover and anticipates the final Passover of the Church in the glory of the kingdom.
“Do this in memory of me”
1341
The command of Jesus to repeat his actions and words “until he comes” does not only ask us to remember Jesus and what he did. It is directed at the liturgical celebration, by the apostles and their successors, of the memorial of Christ, of his life, of his death, of his Resurrection, and of his intercession in the presence of the Father.
