Augustine of Hippo
Catena Aurea · Matthäusevangelium 25
And these shall go away into everlasting punishment: but the righteous into life eternal.
(de Civ. Dei, xxi. 3.) But, they assert, nobody can be at once capable of suffering pain, and incapable of death. It must be that one live in pain, but it need not be that pain kill him; for not even these mortal bodies die from every pain; but the reason that some pain causes their death is, that the connection between the soul and our present body is such that it gives way to extreme pain. But then the soul shall be united to such a body, and in such a way, that no pain shall be able to overcome the connection. There will not then be no death, but an everlasting death, the soul being unable to live, as being without God, and equally unable to rid itself of the pains of body by dying.
