Augustine of Hippo — as excerpted in the Catena Aurea on Mark 15:6-15

“(ubi sup.) It now is clear enough that Mark means by King of the Jews what Matthew means by the word Christ; for no kings but those of the Jews were called Christs. For in this place according to Matthew it is said, What then shall I do with Jesus which is called Christ? There follows, And they cried out again, Crucify him. (Matt. 27:22)”
