End Notes: 

[1*] “O My Father, if it be possible, let this cup pass from Me.” “Absolutely this was possible, but it was impossible according to God’s decree that man was to be redeemed by Christ’s death. Christ knew this, and therefore did not wish for it absolutely, and asks for nothing contrary to His own and the Father’s will. But He merely expresses His natural shrinking from death, His ineffectual and conditionated will, and yet freely submitted Himself to the contrary will of God, that He should die.” “[Christ suffered] to mitigate the dread of death, which was inflicted as a punishment for Adam’s sin, and turn it into joy and the hope of attaining a better life. Christ then obtained for the martyrs exemption from pain and fear in their grievous torments, and caused them to undergo them willingy, and even to rejoice in them. “Christ came,” says S. Chrysostom, “to bear our infirmities, and to give us His strength. And again, Christ by His agony enabled His faithful ones not to fear death, but patiently and even joyfully to meet it from their hope in the resurrection, saying with Hosea and S. Paul, as triumphing over death, ‘Death is swallowed up in victory’”  (1 Cor. xv. 55).” St Thomas Aquinas, Summa Theologica, Tertia Pars, Question 18, Article 5.  ; Cornelious Lapide, The Great Biblical Commentary, Gospel of St Matthew Chapter 26, v. 36. ; (See also St Hilary Commentary) .

[5*] “Jesus has done nought but good, and nevertheless He vouchsafes to subject Himself to punishment, as though He were the worst of malefactors, and I who am guilty of so many sins, will not accept the slight penance of some little shame or suffering which Divine Justice inflicts upon me by the instrumentality of others.” Ibid.

[18*] “Look at Him as He hangs upon this Cross, with His head tortured with thorns, as He hangs upon the three iron nails, and is supported by His Own Wounds! All have abandoned Him, even His own disciples, all deride Him upon the Cross, and blaspheme Him; and why hast Thou abandoned Him, Who hast so greatly loved Him? Jesus had taken upon Himself the sins of the world, although He was Himself the most holy of all men, and even sanctity itself; since He had taken upon Himself to satisfy for all our sins, …Because we had deserved to be abandoned forever in Hell to eternal despair, therefore He chose to be given up to a death deprived of every relief, that thus He might deliver us from eternal death.” … “St. Jerome and others explain that our Savior uttered this lamentation to show not His own despair, but the bitterness which He endured in a death without consolation.” Ibid.
