"from any ashes whatever"

"[Christ's] rising from the grave was a sufficient argument to prove that men are to be raised up by Divine power, not only from their graves, but also from any dust whatever [(non solum de sepulcris, sed etiam de quibuscumque cineribus)]."

     I.e. he did not have "to return to dust [(incinerationem pati, suffer incineration)] so as to give to them who have returned to dust the hope of rising from the dust [(spem resurgendi incineratis post incinerationem, to the incinerated the hope of rising after incineration)]," incinerare being post-classical, and capable of meaning both 1a. "to reduce to ashes (by burning)" and 1b. "to reduce to dust (by decomposition)" (DMLBS), an ambiguity not present in the DMLBS (at least) for cinis:  cineribus < cinis, "1. The residue from a fire," "3. Ashes regarded as the result of destruction or consumption by fire," "4. Ashes as the condition of the body after death (whether cremated or not)" (OLD); "II.A. The ashes of a corpse that is burned," "the person after death," "after burning the corpse" (Lewis (& Short)); "1. residue of combustion" only (DMLBS).  The word in the Vulgate of Gen 3:19 ("dust thou art, and into dust thou shalt return"), by contrast, is pulvis; and in the Vetus Latina, terra (L:  the "allgemeine Form der Vetus Latina"; H:  Jerome's Vulgate (28*)).
