Luke 24:30

He took bread and blessed it. He blessed it by causing it to become His body as in the consecration of the Eucharist. For that Christ thus consecrated it, although Jansenius and some others deny it, is clear:

1. Because S. Matthew, S. Mark, and S. Luke use the same words concerning the institution of the Eucharist, as S. Luke uses here.

2. Because this blessing does not appear to have been given it the commencement of the meal, for Christ wished not to vanish out of their sight before He had eaten with them, lest they might think him a phantom. It was given in the midst, or rather at the end, of the meal. It was not therefore the ordinary blessing on what had been provided for their use, but solemn and eucharistic.

3. This is clear also from the effect which this blessing of the bread had upon the disciples. "their eyes were opened and they knew Him."

4. Furthermore, this is the opinion of the great majority of the Fathers. So the author quoted by S. Chrysostom (Hom. 17) says, "The Lord not only blessed the bread, but gave it with His own hand to Cleopas and his companion. But that which is given by His hand is not only sanctified, but sanctification and a cause of sanctity to the recipient."

Again, "How did the Lord will to make Himself known? By the breaking of bread. We are content then; in the breaking of bread the Lord is made known unto us. In no other way is it His will to reveal Himself. Therefore, although we shall not see Him in bodily form, He has given us His flesh to eat." S. Augustine (Serm. 140 De Temp.)

This passage of Holy Scripture is a proof of the use of one species only in the Eucharist, for it is clear that Christ neither consecrated nor gave the cup to the disciples. After He had blessed the bread, and given it to them, they knew Him, and immediately He vanished out of their sight. S. Augustine, Chrysostom, Bede and others.
