Article 21

In the twenty-first article the question is raised whether the bodies of the damned will be capable of suffering when they are in hell, and if they will suffer from the fire of hell because they will receive the form of the fire of hell in an injurious and harmful way. (See Summa Theologiae, Supplement, q. 86 a. 2 ad 3.)

I do not see how one could find fault with this. For as impassibility is commonly posited to be the gift bestowed upon glorified bodies, it follows that non-glorified bodies will be passible. But that they will receive the form of fire in themselves in a painful manner cannot be denied except by one who denies that bodies of this sort perceive the fire of hell. For it is necessary that a sensible form be perceived if suffering is to follow.
