Jerome
Catena Aurea · Matthäusevangelium 27
Then the soldiers of the governor took Jesus into the common hall, and gathered unto him the whole band of soldiers. And they stripped him, and put on him a scarlet robe. And when they had platted a crown of thorns, they put it upon his head, and a reed in his right hand: and they bowed the knee before him, and mocked him, saying, Hail, king of the Jews! And they spit upon him, and took the reed, and smote him on the head.
All these things we may understand mystically. For as Caiaphas said that it is expedient that one man should die for the people, (John 11:50.) not knowing what he said, so these, in all they did, furnished sacraments to us who believe, though they did them with other intention. In the scarlet robe He bears the bloody works of the Gentiles; by the crown of thorns He takes away the ancient curse; with the reed He destroys poisonous animals; or He held the reed in His hand wherewith to write down the sacrilege of the Jews.
