Whether the fire whereby the world will be cleansed will be of the same species with elemental fire?

Objections

Objection 1 : It would seem that the fire in question is not of the same species as elemental fire. For nothing consumes itself. But that fire will consume the four elements according to a gloss on 2 Pt. 3:12. Therefore that fire will not be of the same species as elemental fire.
Objection 2 : Further, as power is made known by operation, so is nature made known by power. Now that fire will have a different power from the fire which is an element: because it will cleanse the universe, whereas this fire cannot do that. Therefore it will not be of the same species as this.
Objection 3 : Further, in natural bodies those that are of the same species have the same movement. But that fire will have a different movement from the fire that is an element, because it will move in all directions so as to cleanse the whole. Therefore it is not of the same species.
