Augustine of Hippo
Catena Aurea · Johannesevangelium 19
And went again into the judgment hall, and saith unto Jesus, Whence art thou? But Jesus gave him no answer. Then saith Pilate unto him, Speakest thou not unto me? knowest thou not that I have power to crucify thee, and have power to release thee? Jesus answered, Thou couldest have no power at all against me, except it were given thee from above: therefore he that delivered me unto thee hath the greater sin. And from thenceforth Pilate sought to release him.
(Tr. cxvi. 4) In comparing the accounts of the different Evangelists together, we find that this silence was maintained more than once; viz. before the High Priest, before, Herod, and before Pilate. So that the prophecy of Him, As a sheep before her shearers is dumb, so opened He not His mouth, (Isa. 53:7.) was amply fulfilled. To many indeed of the questions put to Him, He did reply, but where He did not reply, this comparison of the sheep shews us that His was not a silence of guilt, but of innocence; not of self-condemnation, but of compassion, and willingness to suffer for the sins of others.
