These abodes [in Hell] 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 ... everlasting fire, express[es] another sort of punishment, which is called by theologians the pain of sense because, like lashes, stripes or other more severe punishments, among which fire, no doubt, produces intense pain, it is felt through the organs of sense. When, moreover, we reflect that this torment is to be eternal, we can see at once that the punishment of the damned includes every kind of suffering.

… there is a purgatorial fire in which the souls of the pious are purified by a temporary punishment so that an entrance may be opened for them into the eternal country in which nothing stained can enter … [Souls detained in purgatory] are helped by the suffrages of the faithful, but especially by the acceptable sacrifice of the altar.
session 25, (December 1563) as quoted by Alice Turner in History of Hell, p. 127
Since it is most revolting to human nature to eat human flesh or drink human blood, therefore God in His infinite wisdom has established the administration of the body and blood of Christ under the forms of bread and wine, which are the ordinary and agreeable food of man.
