This window it is that gives entrance to the dark doctrine, first, of eternal torments; and afterwards of purgatory, and consequently of the walking abroad, especially in places consecrated, solitary, or dark, of the ghosts of men deceased; and thereby to the pretences of exorcism and conjuration of phantasms; as also of invocation of men dead; and to the doctrine of indulgences, that is to say, of exemption for a time, or forever, from the fire of purgatory, wherein these incorporeal substances are pretended by burning to be cleansed, and made fit for heaven. For men being generally possessed before the time of our Saviour, by contagion of the demonology of the Greeks, of an opinion that the souls of men were substances distinct from their bodies, and therefore that when the body was dead, the soul of every man, whether godly or wicked, must subsist somewhere by virtue of its own nature, without acknowledging therein any supernatural gift of God; the doctors of the Church doubted a long time, what was the place which they were to abide in, till they should be reunited to their bodies in the resurrection; supposing for a while, they lay under the altars; but afterwards the Church of Rome found it more profitable to build for them this place of purgatory; which by some other Churches in this latter age has been demolished.
