Origen

“ Chapter XVI.
From what has been said, it will be manifest to intelligent hearers how we have to answer the following: “All the rest of the race will be completely burnt up, and they alone will remain.” ”

“ The Scripture accordingly declares that only those who are unscathed by the fire and the punishments are to remain,—those, viz., whose opinions, and morals, and mind have been purified to the highest degree; while, on the other hand, those of a different nature—those, viz., who, according to their deserts, require the administration of punishment by fire—will be involved in these sufferings with a view to an end which it is suitable for God to bring upon those who have been created in His image, but who have lived in opposition to the will of that nature which is according to His image. ”
