37 And Jesus cried with a loud voice, and gave up the ghost.
[AD 430] Augustine of Hippo on Mark 15:33-37
(de Con. Evan. 3, 17) Luke added to this account the cause of the darkness, that is, the darkening of the sun.

(ubi sup.) Matthew has not related, that the man who brought the sponge filled with vinegar, but that the others spoke about Elias; from whence we gather that both said it.

[AD 735] Bede on Mark 15:33-37
(ubi sup.) This most glorious light took away its rays from the world, lest it should see the Lord hanging, and lest the blasphemers should have the benefit of its light. Wherefore it goes on: And when the sixth hour was come, there was darkness over the whole land until the ninth hour.

(ubi sup.) For when Adam sinned, it is also written that he heard the voice of the Lord, walking in paradise, in the cool after mid-day; (Gen. 3:8.) and in that hour when the first Adam by sinning brought death into the world, in that same hour the second Adam by dying destroyed death. And we must observe, that our Lord was crucified, when the sun was going away from the centre of the world; but at sunrise He celebrated the mysteries of His resurrection; because He died for our sins, but rose again for our justification. Nor need you wonder at the lowliness of His words, at the complaints as of one forsaken, when you look on the offence of the cross, knowing the form of a servant. For as hunger, and thirst, and fatigue were not things proper to the Divinity, but bodily affections; so His saying, Why hast thou forsaken me? was proper to a bodily voice, for the body is never naturally wont to wish to be separated from the life which is joined to it. For although our Saviour Himself said this, He really showed the weakness of His body; He spoke therefore as man, bearing about with Him my feelings, for when placed in danger we fancy that we are deserted by God.

(ubi sup.) These however I suppose were Roman soldiers who did not understand the peculiarity of the Hebrew tongue, but, from His calling Eloi, thought that Elias was called by Him. But if the Jews are understood to have said this, they must be supposed to do this, as accusing Him of folly in calling for the aid of Elias. It goes on: And one ran and filled a sponge full of vinegar, and put it on a reed, and gave him to drink, saying, Let alone: let us see whether Elias will come to take him down. John shows more fully the reason why the vinegar was given to the Lord to drink, saying, that Jesus said, I thirst, (John 19:28.) that the Scriptures might be fulfilled. They however applied a sponge full of vinegar to His mouth.

[AD 1107] Theophylact of Ohrid on Mark 15:33-37
If this had been the time for an eclipse, some one might have said that this that happened was natural, but it was the fourteenth moon, when no eclipse can take place. There follows: And at the ninth hour Jesus cried with a loud voice, saying, Eloi, Eloi, lama sabachthani.

Or, He speaks this as man crucified by God for me, for we men have been forsaken by the Father, but He never has. For hear what He says; I am not alone, because the Father is with me. (John 16:32) Though He may also have said this as being a Jew, according to the flesh, as though He had said, Why hast thou forsaken the Jewish people, so that they have crucified Thy Son? For as we sometimes say, God has put on me, that is, my human nature, so here also we must understand thou hast forsaken me, to mean my nature, or the Jewish people. It goes on: And some of them that stood by, when they heard it, said, Behold, he calleth Elias.

He who both rules over death and commands it dies with power, as its Lord. But what this voice was is declared by Luke: Father, into thy hands I commend my spirit. For Christ would have us understand by this, that from that time the souls of the saints go up into the hands of God. (v. note u, p. 217) For at first the souls of all were held in hell, till He came, who preached the opening of the prison to the captives.

[AD 1274] Pseudo-Jerome on Mark 15:33-37
At the ninth hour, the tenth piece of money which had been lost is found, by the overturning of the house.

Here he points out a similitude for the Jews; a sponge on a reed, weak, dry, fit for burning; they fill it with vinegar, that is, with wickedness and guile.

Though the flesh was weak, yet the heavenly voice, which said, Open me the gates of righteousness, (Ps. 117:19) waxed strong.  Wherefore there follows: And Jesus cried with a loud voice, and gave up the ghost. We who are of the earth die with a very low voice, or with no voice at all; but He who descended from heaven breathed His last with a loud voice.

[AD 430] Augustine of Hippo on Mark 15:37
Those robbers crucified next to him, did they breathe their last when they wanted to? They were held fast by the chains of the flesh because they were not the creators of the flesh. Fastened by nails, they were tormented for a long time because they were not masters of their infirmity. But the Lord took on flesh in the virgin’s womb when he wished it. He came forth to humanity when he wished it. He lived in history as long as he wished it. He departed from the flesh when he wished it. This is a sign of power, not of necessity.

[AD 430] Augustine of Hippo on Mark 15:37
He departed by his [own] power; for he had not come by necessity. And so some marveled more at his power of dying than at his power of performing miracles.

[AD 735] Bede on Mark 15:37
But Jesus, having cried out with a loud voice, expired. What the Lord said with this loud voice, Luke clearly indicates, saying: Father, into your hands I commend my spirit. And having said this, he expired (Luke 23). What John writes, however, that when Jesus had received the vinegar, he said: It is finished, and bowing his head, gave up his spirit (John 19), between that which he said: It is finished, and that: And bowing his head, gave up his spirit, the loud voice was emitted, which John kept silent about, but the other three mentioned.
