15 And so Pilate, willing to content the people, released Barabbas unto them, and delivered Jesus, when he had scourged him, to be crucified.
[AD 430] Augustine of Hippo on Mark 15:6-15
(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 showed 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.

(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)

[AD 735] Bede on Mark 15:6-15
(ubi sup.) Pilate furnished many opportunities of releasing Jesus, in the first place contrasting a robber with the Just One. Wherefore it is said, Now at that feast he released unto them one prisoner, whomsoever they desired.

(ubi sup.) This demand which the Jews made with such toil to themselves still sticks to them. Because, when the choice was given to them, they chose a robber instead of Christ, a murderer instead of the Saviour, they deservedly lost their salvation and their life, and they subjected themselves to such a degree to robbery and sedition, that they lost their country and their kingdom which they preferred to Christ, and never regained their liberty, body or soul. Then Pilate gives another opportunity of releasing the Saviour, when there follows, And Pilate answered and said again unto them, What will ye then that I should do unto the King of the Jews?

(ubi sup.) But the Jews giving loose to their madness do not answer the question of the judge. Wherefore it goes on, And they cried out the more exceedingly, Crucify him, that those words of the Prophet Jeremiah might be fulfilled, Mine heritage is unto me as a lion in the forest, it crieth out against me. (Jer. 12:8) There follows, 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.) We must understand that Jesus was scourged by no other than Pilate himself. For John writes, Pilate took Jesus, and scourged him, (John 13:1) which we must suppose that he did, that the Jews might be satisfied with His pains and insults, and cease from thirsting for His blood.

[AD 1107] Theophylact of Ohrid on Mark 15:6-15
Now see the wickedness of the Jews, and the moderation of Pilate, though he too was worthy of condemnation for not resisting the people. For they cried out, Crucify; he faintly tries to save Jesus from their determined sentence, and again puts a question to them. Wherefore there follows, Then Pilate said unto them, Why, what evil hath he done? For he wished in this way to find an opportunity for releasing Christ, who was innocent.

He wished indeed to satisfy the people, that is, to do their will, not what was agreeable to justice and to God.

[AD 1274] Pseudo-Jerome on Mark 15:6-15
Here are two goats; one is the scape goat, that is, one loosed and sent out into the wilderness of hell with the sin of the people; the other is slain, as a lamb, for the sins of those who are forgiven. The Lord's portion is always slain; the devil's part, (for he is the master of those men, which is the meaning of Barabbas,) when freed, is cast headlong into hell.

[AD 1274] Glossa Ordinaria on Mark 15:6-15
(non occ.) Which indeed he was accustomed to do, to obtain favour with the people, and above all, on the feast day, when the people of the whole province of the Jews flocked to Jerusalem. And that the wickedness of the Jews might appear the greater, the enormity of the sin of the robber, whom they preferred to Christ, is next described. Wherefore there follows: And there was one Barabbas, who lay bound with them that had made insurrection with him, who had committed murder in the insurrection. In which words their wickedness is shown both from the heinousness of his signal crime, in that he had committed murder, and from the way in which he did it, because he had in doing it raised a sedition and disturbed the city, and also because his crime was notorious, for he was bound with seditious persons. It goes on: And the multitude, when it had come up, began to desire him to do as he had ever done unto them.

[AD 258] Cyprian on Mark 15:15
He himself suffered the lash, in whose name his servants now scourge the devil and his angels. He who now crowns the martyrs with eternal garlands was himself crowned with thorns.

[AD 373] Ephrem the Syrian on Mark 15:15
[The daughter of Zion] repaid him with evil for the immensity of his grace. The Father had washed her from her blood, but she defiled his Son with her spitting. The Father had clothed her with fine linen and purple, but she clothed him with garments of mockery. He had placed a crown of glory on her head, but she plaited a crown of thorns for him. He had nourished her with choicest food13 and honey, but she gave him gall. He had given her pure wine, but she offered him vinegar in a sponge. The One who had introduced her into cities, she drove out into the desert. The One who had put shoes on her feet, she made hasten barefoot towards Golgotha. The One who had girded her loins with sapphire, she pierced in the side with a lance. When she had outraged the servants [of God] and killed the prophets, she was led into captivity to Babylon, and when the time of her punishment was completed, her return [from captivity] took place.

[AD 430] Augustine of Hippo on Mark 15:15
The criminal escaped; Christ was condemned. The one guilty of many crimes received a pardon; he who had remitted the crimes of all who confess was condemned. And yet the cross itself also, if you reflect upon it, was a courtroom. In the middle of it stood the final judge.

[AD 430] Augustine of Hippo on Mark 15:15
For Christ was not separated from the ungodly, but was judged with the ungodly; for it was said about him, “He was counted among the wicked.”

[AD 735] Bede on Mark 15:15
But Pilate, willing to satisfy the people, released Barabbas to them and delivered Jesus, after having him scourged, to be crucified. Jesus, however, is understood to have been scourged not by another, but by Pilate himself. For John writes openly: They all cried again, saying: Not this man, but Barabbas. Now Barabbas was a robber. Then Pilate took Jesus and scourged him (John XVIII). And then he adds: And the soldiers, weaving a crown of thorns, placed it on his head, etc. (John XIX). Indeed, he is believed to have done this and to have delivered him to the soldiers to be mocked, so that, satisfied with his pains and insults, they might willingly stop desiring his death. This was done, for it was written: Many are the stripes of the wicked (Psalm XXXI), he was scourged so that we might be freed from beatings, the Scripture saying: The scourge shall not approach your tabernacle (Psalm XC).
