With reference to the second point, that a creature may be changed for better or worse, it is always to be understood that this can only be done by the permission and indeed by the power of God, and that this is only done in order to correct or to punish, but that God very often allows devils to act as His ministers and His servants, but throughout all it is God alone who can afflict and it is He alone who can heal, for “I kill and I make alive” (Deuteronomy 32:39). And so evil angels may and do perform the will of God. To this also S. Augustine bears witness when he says: There are in truth magic spells and evil charms, which not only often afflict men with diseases but even kill them outright. We must also endeavour clearly to understand what actually happens when nowadays by the power of the devil wizards and witches are changed into wolves and other savage beasts. The Canon, however, speaks of some bodily and lasting change, and does not discuss those extraordinary things which may be done by glamour of which S. Augustine speaks in the 18th book and the 17th chapter of Of the City of God, when he reports many strange tales of that famous witch Circe, and of the companions of Diomedes and of the father of Praestantius. This will be discussed in detail in the Second Part.
Whether it be a Heresy to Maintain that Witches Exist.
The second part of our inquiry is this, whether obstinately to maintain that witches exist is heretical. The questions arises whether people who hold that witches do not exist are to be regarded as notorious heretics, or whether they are to be regarded as gravely suspect of holding heretical opinions. It seems that the first opinion is the correct one. For this is undoubtedly in accordance with the opinion of the learned Bernard. And yet those persons who openly and obstinately persevere in heresy must be proved to be heretics by unshaken evidence, and such demonstration is generally one of three kinds; either a man has openly preached and proclaimed heretical doctrines; or he is proved to be a heretic by the evidence of trustworthy witnesses; or he is proved to be a heretic by his own free confession. And yet there are some who rashly opposing themselves to all authority publicly proclaim that witches do not exist, or at any rate that they can in no way afflict and hurt mankind. Wherefore, strictly speaking those who are convicted of such evil doctrine may be excommunicated, since they are openly and unmistakably to be convicted of false doctrine. The reader may consult the works of Bernard, where he will find that this sentence is just, right, and true. Yet perhaps this may seem to be altogether too severe a judgement mainly because of the penalties which follow upon excommunication: for the Canon prescribes that a cleric is to be degraded and that a layman is to be handed over to the power of the secular courts, who are admonished to punish him as his offence deserves. Moreover, we must take into consideration the very great numbers of persons who, owing to their ignorance, will surely be found guilty of this error. And since the error is very common the rigor of strict justice may be tempered with mercy. And it is indeed our intention to try to make excuses for those who are guilty of this heresy rather than to accuse them of being infected with the malice of heresy. It is preferable then that if a man should be even gravely suspected of holding this false opinion he should not be immediately condemned for the grave crime of heresy. (See the gloss of Bernard111 upon the word “Condemned.”) One may in truth proceed against such a man as against a person who is gravely suspect, but he is not to be condemned in his absence and without a hearing. And yet the suspicion may be very grave, and we cannot refrain from suspecting these people, for their frivolous assertions do certainly seem to affect the purity of the faith. For there are three kinds of suspicion—a light suspicion, a serious suspicion, and a grave suspicion. These are treated of in the chapter on Accusations and in the chapter on Contumacy, Book 6, “On Heretics.” And these things come under the cognizance of the archidiaconal court. Reference may also be made to the
