Catena Aurea · Markusevangelium 15
Now at that feast he released unto them one prisoner, whomsoever they desired. And there was one named Barabbas, which lay bound with them that had made insurrection with him, who had committed murder in the insurrection. And the multitude crying aloud began to desire him to do as he had ever done unto them. But Pilate answered them, saying, Will ye that I release unto you the King of the Jews? For he knew that the Chief Priests had delivered him for envy. But the Chief Priests moved the people, that he should rather release Barabbas unto them. And Pilate answered and said again unto them, What will ye then that I shall do unto him whom ye call the King of the Jews? And they cried out again, Crucify him. Then Pilate said unto them, Why, what evil hath he done? And they cried out the more exceedingly, Crucify him. And so Pilate, willing to content the people, released Barabbas unto them, and delivered Jesus, when he had scourged him, to be crucified.
(ubi sup.) No one can feel it a difficulty that Matthew is silent as to their asking some one to be released unto them, which Mark here mentions; for it is a thing of no consequence that one should mention a thing which another leaves out. There follows: But Pilate answered them, saying, Will ye that I release unto you the King of the Jews? For he knew that the Chief Priests had delivered him for envy. Some one may ask, which were the words of which Pilate made use, those which are related by Matthew, or those which Mark relates; for there seems to be a difference between, Whom will ye that I release unto you? Barabbas, or Jesus which is called Christ? as Matthew has it; and, Will ye that I release unto you the King of the Jews? (Matt. 27:17) as is here said. But since they gave to kings the name of Christs, he who said this man or that must have asked whether they wished the King of the Jews to be released unto them, that is, Christ. It makes no difference to the sense that Mark has said nothing of Barabbas, wishing only to mention what belonged to the Lord, since by their answer he sufficiently shewed whom they wished to have released to them. For there follows, But the Chief Priests moved the people that he should rather release unto them Barabbas.
