These abodes are not all of the same nature, for among them is that most loathsome and dark prison in which the souls of the damned are tormented with the unclean spirits in eternal and inextinguishable fire. This place is called gehenna, the bottomless pit, and is hell strictly so called.
Among them is also the fire of purgatory, in which the souls of just men are cleansed by a temporary punishment, in order to be admitted into their eternal country, into which nothing defiled entereth. The truth of this doctrine, founded, as holy Councils declare,’ on Scripture, and confirmed by Apostolic tradition, demands exposition from the pastor, all the more diligent and frequent, because we live in times when men endure not sound doctrine.
Lastly, the third kind of abode is that into which the souls of the just before the coming of Christ the Lord, were received, and where, without experiencing any sort of pain, but supported by the blessed hope of redemption, they enjoyed peaceful repose. To liberate these holy souls, who, in the bosom of Abraham [Hades] were expecting the Saviour, Christ the Lord descended into hell.
