Reply Obj. 1: With regard to Christ's death, His patience and constancy in enduring death are commended, and all the more that His death was the more despicable: but in His honorable burial we can see the power of the dying Man, who, even in death, frustrated the intent of His murderers, and was buried with honor: and thereby is foreshadowed the devotion of the faithful who in the time to come were to serve the dead Christ.
Reply Obj. 2: On that expression of the Evangelist (John 19:40) that they buried Him "as the manner of the Jews is to bury," Augustine says (Tract. in Joan. cxx): "He admonishes us that in offices of this kind which are rendered to the dead, the custom of each nation should be observed." Now it was the custom of this people to anoint bodies with various spices in order the longer to preserve them from corruption [*Cf. Catena Aurea in Joan. xix]. Accordingly it is said in De Doctr. Christ. iii that "in all such things, it is not the use thereof, but the luxury of the user that is at fault"; and, farther on: "what in other persons is frequently criminal, in a divine or prophetic person is a sign of something great." For myrrh and aloes by their bitterness denote penance, by which man keeps Christ within himself without the corruption of sin; while the odor of the ointments expresses good report.
Reply Obj. 3: Myrrh and aloes were used on Christ's body in order that it might be preserved from corruption, and this seemed to imply a certain need (in the body): hence the example is set us that we may lawfully use precious things medicinally, from the need of preserving our body. But the wrapping up of the body was merely a question of becoming propriety. And we ought to content ourselves with simplicity in such things. Yet, as Jerome observes, by this act was denoted that "he swathes Jesus in clean linen, who receives Him with a pure soul." Hence, as Bede says on Mark 15:46: "The Church's custom has prevailed for the sacrifice of the altar to be offered not upon silk, nor upon dyed cloth, but on linen of the earth; as the Lord's body was buried in a clean winding-sheet."
Reply Obj. 4: Christ was buried "in a garden" to express that by His death and burial we are delivered from the death which we incur through Adam's sin committed in the garden of paradise. But for this "was our Lord buried in the grave of a stranger," as Augustine says in a sermon (ccxlviii), "because He died for the salvation of others; and a sepulchre is the abode of death." Also the extent of the poverty endured for us can be thereby estimated: since He who while living had no home, after death was laid to rest in another's tomb, and being naked was clothed by Joseph. But He is laid in a "new" sepulchre, as Jerome observes on Matt. 27:60, "lest after the resurrection it might be pretended that someone else had risen, while the other corpses remained. The new sepulchre can also denote Mary's virginal womb." And furthermore it may be understood that all of us are renewed by Christ's burial; death and corruption being destroyed. Moreover, He was buried in a monument "hewn out of a rock," as Jerome says on Matt. 27:64, "lest, if it had been constructed of many stones, they might say that He was stolen away by digging away the foundations of the tomb." Hence the "great stone" which was set shows that "the tomb could not be opened except by the help of many hands. Again, if He had been buried in the earth, they might have said: They dug up the soil and stole Him away," as Augustine observes [*Cf. Catena Aurea]. Hilary (Comment. in Matth. cap. xxxiii) gives the mystical interpretation, saying that "by the teaching of the apostles, Christ is borne into the stony heart of the gentile; for it is hewn out by the process of teaching, unpolished and new, untenanted and open to the entrance of the fear of God. And since naught besides Him must enter into our hearts, a great stone is rolled against the door." Furthermore, as Origen says (Tract. xxxv in Matth.): "It was not written by hazard: 'Joseph wrapped Christ's body in a clean winding-sheet, and placed it in a new monument,'" and that "'he rolled a great stone,' because all things around the body of Jesus are clean, and new, and exceeding great." _______________________
THIRD ARTICLE [III, Q. 51, Art. 3]
Whether Christ's Body Was Reduced to Dust in the Tomb?
Objection 1: It would seem that Christ's body was reduced to dust in the tomb. For just as man dies in punishment of his first parent's sin, so also does he return to dust, since it was said to the first man after his sin: "Dust thou art, and into dust thou shalt return" (Gen. 3:19). But Christ endured death in order to deliver us from death. Therefore His body ought to be made to return to dust, so as to free us from the same penalty.
Obj. 2: Further, Christ's body was of the same nature as ours. But directly after death our bodies begin to dissolve into dust, and are disposed towards putrefaction, because when the natural heat departs, there supervenes heat from without which causes corruption. Therefore it seems that the same thing happened to Christ's body.
Obj. 3: Further, as stated above (A. 1), Christ willed to be buried in order to furnish men with the hope of rising likewise from the grave. Consequently, He sought likewise to return to dust so as to give to them who have returned to dust the hope of rising from the dust.
On the contrary, It is written (Ps. 15:10): "Nor wilt Thou suffer Thy holy one to see corruption": and Damascene (De Fide Orth. iii) expounds this of the corruption which comes of dissolving into elements.
