Charismatic practice goes right in the face of what St. John of the Cross, and others, said you SHOULD NOT do when it comes to locutions.
3. There is always ground for fear that they proceed from the devil rather than from God; for the devil has more influence in that which is exterior and corporeal, and can more easily deceive us therein than in what is more interior. And these bodily forms and objects, the more exterior they are, the less do they profit the interior spiritual man, by reason of the great distance and disproportion subsisting between the corporeal and the spiritual. For, although these things communicate some spirituality, as is always the case when they proceed from God, yet it is much less than it would have been, had they been more spiritual and interior; and thus they become more easily and readily occasions of error, presumption, and vanity. As they are so palpable and so material they excite the senses greatly, and the soul is led to consider them the more important, the more they are felt. It runs after them and abandons the secure guidance of faith, thinking that the light they give is a guide and means to that which it desires, union with God. Thus the soul, the more it makes of such things, the more it strays from the perfect way and means, that is, the faith. Besides, when the soul perceives itself subject to these extraordinary visitations, self-esteem very frequently enters in, and it thinks itself to be some thing in the eyes of God, which is contrary to humility. The devil also knows too well how to insinuate into the soul a secret, and sometimes an open, self-satisfaction. For this end he frequently presents to the eyes the forms of saints, and most beautiful lights; he causes voices well dissembled to strike the ear, and delicious odours the smell; he produces sweetness in the mouth, and thrills of pleasure in the sense of touch; and all to make us long for such things that he may lead us astray into much evil.
