We have, indeed, the authority of the whole of Scriptural teaching that God allows the devil to afflict sinners more than the just. For although that most just man, Job, was stricken, yet he was not so particularly or directly in respect of the procreant function. And it may be said that, when a married couple are afflicted in this way, either both the parties or one of them is not living in a state of grace; and this opinion is substantiated in the Scriptures both by authority and by reason. For the Angel said to Tobias:216 The devil receives power against those who are given over to lust: and he proved it in the slaying of the seven husbands of the virgin Sara.
Cassian, in his Collation of the Fathers, quotes S. Antony as saying that the devil can in no way enter our mind or body unless he has first deprived it of all holy thoughts and made it empty and bare of spiritual contemplation. These words should not be applied to an evil affliction over the whole of the body, for when Job was so afflicted he was not denuded of Divine grace; but they have particular reference to a particular infirmity inflicted upon the body for some sin. And the infirmity we are considering can only be due to the sin of incontinence. For, as we have said, God allows the devil more power over that act than over other human acts, because of its natural nastiness, and because by it the first sin was handed down to posterity. Therefore when people joined in matrimony have for some sin been deprived of Divine help, God allows them to be bewitched chiefly in their procreant functions.
But if it is asked of what sort are those sins, it can be said, according to S. Jerome, that even in a state of matrimony it is possible to commit the sin of incontinence in various ways. See the text: He who loves his wife to excess is an adulterer. And they who love in this way are more liable to be bewitched after the manner we have said.
The remedies of the Church, then, are twofold: one applicable in the public court, the other in the tribunal of the confessional. As for the first, when it has been publicly found that the impotence is due to witchcraft, then it must be distinguished whether it is temporary or permanent. If it is only temporary, it does not annul the marriage. And it is assumed to be temporary if, within the space of three years, by using every possible expedient of the Sacraments of the Church and other remedies, a cure can be caused. But if, after that time, they cannot be cured by any remedy, then it is assumed to be permanent.
Now the disability either precedes both the contract and the consummation of marriage; and in this case it impedes the contract: or it follows the contract but precedes the consummation; and in this case it annuls the contract. For men are very often bewitched in this way because they have cast off their former mistresses, who, hoping that they were to be married and being disappointed, so bewitch the men that they cannot copulate with another woman. And in such a case, according to the opinion of many, the marriage already contracted is annulled, unless, like Our Blessed Lady and S. Joseph they are willing to live together in holy continence. This opinion is supported by the Canon where it says (23, q. 1) that a marriage is confirmed by the carnal act. And a little later it says that impotence before such confirmation dissolves the ties of marriage.
Or else the disability follows the consummation of a marriage, and then it does not dissolve the bonds of matrimony. Much more to this effect is noted by the Doctors, where in various writings they treat of the obstruction due to witchcraft; but since it is not precisely relevant to the present inquiry, it is here omitted.
But some may find it difficult to understand how this function can be obstructed in respect of one woman but not of another. S. Bonaventura answers that this may be because some witch has persuaded the devil to effect this only with respect to one woman, or because God will not allow the obstruction
