At the Last Supper, was the bread and wine actually the body and blood of Christ?

Question: I have wondered about at the Last Supper, was the bread and wine actually the body and blood of Christ even though he was alive at the table at that moment? In other words, was that event the very first transubstantiation of the bread and wine in history that occurred? So, the first Last Supper with the disciples was bread and wine then I would imagine breaking an actual loaf of bread caused crumbs. Also, the Early Church would have used leavened or unleavened bread as the Holy Eucharist? Was there any serious concern when any loose bread happened in the Early Church? Did they know it was the true Body of Christ to retrieve it properly or, were they oblivious to it?

Answer: Firstly, yes, the first act Transubstantiation (the changing of the substance, not the appearance of the bread and wine into the Eucharist) did happen at the last supper. The first act of Transubstantiation took place then for the very reason that it required the direct action of God in order for it to take place. Christ demonstrated multiple times his power over the laws of nature – multiplying loaves and fishes, walking on water, raising the dead etc. – and it is by His divine power that the Eucharist exists. First, He must institute the sacrifice Himself and then He gives His Apostles and Church the power to continue it. As He is the new Passover lamb, who willingly gives His life in sacrifice – in opposition to the former Passover lambs who were taken by force – He therefore of His own Divine power also gives them the new sacrifice to celebrate, the new Victim giving Himself in offering.

When it comes to the Passover meal and the institution of the Eucharist that followed it, the rules were very strict about how the foods were to be treated and that nothing was to be wasted or left over. They had to ensure that it was totally consumed and if they could not finish it, then they would place the rest in the fire. In Exodus 12, 10 God tells Moses: “You must not keep any of it beyond the morning; whatever is left over in the morning must be burned up.” The Passover food was not to be mixed in any way with the foods consumed after as it was a sacrificial meal. As to the bread that was used, it was unleavened bread, that was a requirement for the Passover meal. A loaf of unleavened bread looks very different from what we are used to in terms of loaves of bread and has a very different consistency. It is thin, but not flat and generally has a much lesser tendency to fragment, which is why they literally have to tear it apart; however it still would leave some particles. The hosts we use are also made of unleavened bread and unleavened bread is a requirement for the celebration of the Mass.

We know that plates/platters would have been used for the foods they ate. The early church had a special cloth they would place over the area where they were celebrating the Eucharist to ensure that no particles were lost. This is where the corporal that we use now comes from. This is also where the paten (the gold plate used at Mass) takes its beginning from. St. Hippolytus of Rome, a bishop of the 2nd century, wrote these instructions in The Apostolic Tradition: But let each of the faithful be zealous, before he eats anything else, to receive the eucharist ... let each one take care that no unbeliever taste the eucharist, nor a mouse nor any other animal, and that nothing of it fall or be lost; for the body of Christ is to be eaten by believers and must not be despised. And so we see that the early Church was very concerned with the Eucharist and any particles as they possessed the knowledge that it was not simply bread, but the body of Christ.
