Whether Christ's body was reduced to dust in the tomb?

Objections

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" (Gn. 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.
Objection 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.
Objection 3 : Further, as stated above (Article [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.
