Hilary of Poitiers
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.
Or otherwise; The Lord having taken upon Him all the infirmities of our body, is then covered with the scarlet coloured blood of all the martyrs, to whom is due the kingdom with Him; He is crowned with thorns, that is, with the sins of the Gentiles who once pierced Him, for there is a prick in thorns of which is woven the crown of victory for Christ. In the reed, He takes into His hand and supports the weakness and frailty of the Gentiles; and His head is smitten therewith that the weakness of the Gentiles sustained by Christ’s hand may rest on God the Father, who is His head.
