John Chrysostom — as excerpted in the Catena Aurea on John 18:28-32

“(Hom. lxxxiii. 4) Or, they were not allowed by the Roman law to put Him to death themselves. Or, Pilate having said, Judge Him according to your law, they reply, It is not lawful for us: His sin is not a Jewish one, He hath not sinned according to our law: His offence is political, He calls Himself a King. Or they wished to have Him crucified, to add infamy to death: they not being allowed to put to death in this way themselves. They put to death in another way, as we see in the stoning of Stephen: That the saying of Jesus might be fulfilled, which He spake, signifying what death He should die. Which was fulfilled in that He was crucified, or in that He was put to death by Gentiles as well as Jews.”
