Augustine of Hippo — as excerpted in the Catena Aurea on John 19:12-16

“(Tr. cxvi) The Jews thought they could alarm Pilate more by the mention of Cæsar, than by telling him of their law, as they had done above; We have a law, and by that law He ought to die, because He made Himself the Son of God. So it follows, But the Jews cried out, saying, If thou let this Man go, thou art not Cæsar’s friend; whosoever maketh himself a king speaketh against Cæsar.”
