Whether all will rise again from ashes?

Objections

Objection 1 : It would seem that all will not rise again from ashes. For Christ's resurrection is the exemplar of ours. Yet His resurrection was not from ashes, for His flesh saw not corruption according to Ps. 15:10; Acts 2:27,31. Therefore neither will all rise again from ashes.
Objection 2 : Further, the human body is not always burned. Yet a thing cannot be reduced to ashes unless it be burned. Therefore not all will rise again from ashes.
Objection 3 : Further, the body of a dead man is not reduced to ashes immediately after death. But some will rise again at once after death, according to the text (Sent. iv, D, 43), namely those who will be found living. Therefore all will not rise again from ashes.
Objection 4 : Further, the term "wherefrom" corresponds to the term "whereto." Now the term "whereto" of the resurrection is not the same in the good as in the wicked: "We shall all indeed rise again, but we shall not all be changed" (1 Cor. 15:51). Therefore the term "wherefrom" is not the same. And thus, if the wicked rise again from ashes, the good will not rise again from ashes.
