48 Again, the Apostle knows nothing in Christ about fear of pain. When He wishes to speak of the dispensation of the Passion, He includes it in the mystery of Christ's Divinity. Forgiving us all our trespasses, blotting out the bond written in ordinances, that was against us, which was contrary to us: taking it away, and nailing it to the cross; stripping off from Himself His flesh, He made a show of principalities and powers openly triumphing over them in Himself. Was that the power, think you, to yield to the wound of the nail, to wince under the piercing blow, to convert itself into a nature that can feel pain?
Yet the Apostle, who speaks as the mouthpiece of Christ, relating the work of our salvation through the Lord, describes the death of Christ as 'stripping off from Himself His flesh, boldly putting to shame the powers and triumphing over them in Himself.' If His passion was a necessity of nature and not the free gift of your salvation: if the cross was merely the suffering of wounds, and not the fixing upon Himself of the decree of death made out against you: if His dying was a violence done by death, and not the stripping off of the flesh by the power of God: lastly, if His death itself was anything but a dishonouring of powers, an act of boldness, a triumph: then ascribe to Him infirmity, because He was therein subject to necessity and nature, to force, to fear and disgrace.
But if it is the exact opposite in the mystery of the Passion, as it was preached to us, who, pray, can be so senseless as to repudiate the faith taught by the Apostles, to reverse all feelings of religion, to distort into the dishonourable charge of natural weakness, what was an act of free-will, a mystery, a display of power and boldness, a triumph? And what a triumph it was, when He offered Himself to those who sought to crucify Him, and they could not endure His presence: when He stood under sentence of death, Who shortly was to sit on the right hand of power: when He prayed for His persecutors while the nails were driven through Him: when He completed the mystery as He drained the draught of vinegar; when He was numbered among the transgressors and meanwhile granted Paradise: that when He was lifted on the tree, the earth quaked: when He hung on the cross, sun and day were put to flight: that He left His own body, yet called life back to the bodies of others: was buried a corpse and rose again God: as man suffered all weaknesses for our sakes, as God triumphed in them all.
