John Chrysostom
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.
He gave thanks to instruct us after what manner we ought to celebrate this mystery, and shewed also thereby that He came not to His Passion against His will. Also He taught us to bear whatsoever we suffer with thanksgiving, and infused into us good hopes. For if the type of this sacrifice, to wit, the offering of the paschal lamb, became the deliverance of the people from Egyptian bondage, much moreshall the reality thereof be the deliverance of the world. And gave it to them, saying, Drink ye all of it. That they should not be distressed at hearing this, He first drank His own blood to lead them without fear to the communion of these mysteries.
