Catena Aurea · Matthäusevangelium 26
And he took the cup, and gave thanks, and gave it to them, saying, Drink ye all of it; For this is my blood of the new testament, which is shed for many for the remission of sins. But I say unto you, I will not drink henceforth of this fruit of the vine, until that day when I drink it new with you in my Father’s kingdom.
(non occ.) As the refreshment of the body is wrought by means of meat and drink, so under the form of meat and drink the Lord has provided for us spiritual refreshment. And it was suitable that for the shewing forth the Lord’s Passion this Sacrament should be instituted under both kinds. For in His Passion He shed His Blood, and so His Blood was separated from His Body. It behoved therefore, that for representation of His Passion, bread and wine should be separately set forth, which are the Sacrament of the Body and Blood. But it should be known, that under both kinds the whole of Christ is contained; under the bread is contained the Blood, together with the Body; under the wine, the Body together with the Blood.
