4:1), examine spirits, than in all things that concern the power of the Roman Church (the abuse whereof either they suspected not, or had benefit by it), to discredit their testimony, in respect of too rash belief of reports; which the most sincere men, without great knowledge of natural causes, such as the fathers were, are commonly the most subject to. For naturally, the best men are the least suspicious of fraudulent purposes. Gregory the Pope and St. Bernard have somewhat of apparitions of ghosts, that said they were in purgatory; and so has our Bede: but nowhere, I believe, but by report from others. But if they, or any other, relate any such stories of their own knowledge, they shall not thereby confirm the more such vain reports; but discover their own infirmity, or fraud.
