8. There are so many ways of ascertaining the nature of these locutions, that if a person be once deceived, he will not be deceived often. I mean, that a soul accustomed to them, and on its guard, will most clearly see what they are; for, setting other considerations aside which prove what I have said, the human locution produces no effect, neither does the soul accept it,--though it must admit the other, whether we like it or not,--nor does it believe it; on the contrary, it is known to be a delusion of the understanding, and is therefore put away as we would put away the ravings of a lunatic. 9. But as to the divine locution, we listen to that as we do to a person of great holiness, learning, or authority, whom we know to be incapable of uttering a falsehood. And yet this is an inadequate illustration; for these locutions proceed occasionally in such great majesty that, without our recollecting who it is that utters them, they make us tremble if they be words of reproof, and die of love if words of love. They are also, as I have said, [7] matters of which the memory has not the least recollection; and expressions so full are uttered so rapidly, that much time must have been spent in arranging them, if we formed them ourselves; and so it seems to me that we cannot possibly be ignorant at the time that we have never formed them ourselves at all. 10. There is no reason, therefore, why I should dwell longer on this matter. It is a wonder to me that any experienced person, unless he deliberately chooses to do so, can fall into delusions. It has often happened to me, when I had doubts, to distrust what I had heard, and to think that it was all imagination,--but this I did afterwards: for at the moment that is impossible,--and at a later time to see the whole fulfilled; for our Lord makes the words dwell in the memory so that they cannot be forgotten. Now, that which comes forth from our understanding is, as it were, the first movement of thought, which passes away and is forgotten; but the divine locution is a work done; and though some of it may be forgotten, and time have lapsed, yet is not so wholly forgotten that the memory loses all traces of what was once spoken,--unless, indeed, after very long time, or unless the locution were words of grace or of instruction. But as to prophetic words, they are never forgotten, in my opinion; at least, I have never forgotten any,--and yet my memory is weak.
