O precious and wonderful banquet!
Since it was the will of God's only-begotten Son that men should share in his divinity, he assumed our nature in order that by becoming man he might make men gods. Moreover, when he took our flesh he dedicated the whole of its substance to our salvation. He offered his body to God the Father on the altar of the cross as a sacrifice for our reconciliation. He shed his blood for our ransom and purification, so that we might be redeemed from our wretched state of bondage and cleansed from all sin. But to ensure that the memory of so great a gift would abide with us for ever, he left his body as food and his blood as drink for the faithful to consume in the form of bread and wine.
O precious and wonderful banquet, that brings us salvation and contains all sweetness! Could anything be of more intrinsic value? Under the old law it was the flesh of calves and goats that was offered, but here Christ himself, the true God, is set before us as our food. What could be more wonderful than this? No other sacrament has greater healing power; through it sins are purged away, virtues are increased, and the soul is enriched with an abundance of every spiritual gift. It is offered in the Church for the living and the dead, so that what was instituted for the salvation of all may be for the benefit of all. Yet, in the end, no one can fully express the sweetness of this sacrament, in which spiritual delight is tasted at its very source, and in which we renew the memory of that surpassing love for us which Christ revealed in his passion.
It was to impress the vastness of this love more firmly upon the hearts of the faithful that our Lord instituted this sacrament at the Last Supper. As he was on the point of leaving the world to go to the Father, after celebrating the Passover with his disciples, he left it as a perpetual memorial of his passion. It was the fulfillment of ancient figures* and the greatest of all his miracles, while for those who were to experience the sorrow of his departure, it was destined to be a unique and abiding consolation.
From the book of Exodus*
24:1-11
They saw God, and they ate and drank
Moses himself was told, "Come up to the Lord, you and Aaron, with Nadab, Abihu, and seventy of the elders of Israel. You shall all worship at some distance, but Moses alone is to come close to the Lord; the others shall not come too near, and the people shall not come up at all with Moses."
When Moses came to the people and related all the words and ordinances of the Lord, they all answered with one voice, "We will do everything that the Lord has told us." Moses then wrote down all the words of the Lord and, rising early the next day, he erected at the foot of the mountain an altar and twelve pillars for the twelve tribes of Israel.
Then, having sent certain young men of the Israelites to offer holocausts and sacrifice young bulls as peace offerings to the Lord, Moses took half of the blood and put it in large bowls; the other half he splashed on the altar. Taking the book of the covenant, he read it aloud to the people, who answered, "All that the Lord has said, we will heed and do." Then he took the blood and sprinkled it on the people, saying, "This is the blood of the covenant which the Lord has made with you in accordance with all these words of his."
Moses then went up with Aaron, Nadab, Abihu, and seventy elders of Israel, and they beheld the God of Israel. Under his feet there appeared to be sapphire tilework, as clear as the sky itself. Yet he did not smite these chosen Israelites. After gazing on God, they could still eat and drink.
