Augustine's Ninth Question.—Whether after an illusion such as happens in a dream, any man may receive the body of our Lord, or if he be a priest, celebrate the Divine mysteries?
Gregory answers.—The Testament of the Old Law, as has been said already in the article above, calls such a man polluted, and allows him not to enter into the church till the evening after being washed with water. Which, nevertheless, spiritual people, taking in another sense, will understand in the same manner as above; because he is imposed upon as it were in a dream, who, being tempted with filthiness, is defiled by real representations in thought, and he is to be washed with water, that he may cleanse away the sins of thought with tears; and unless the fire of temptation depart before, may know himself to be guilty as it were until the evening. But discretion is very necessary in that illusion, that one may seriously consider what causes it to happen in the mind of the person sleeping; for sometimes it proceeds from excess of eating or drinking; sometimes from the superfluity or infirmity of nature, and sometimes from the thoughts. And when it happens, either through superfluity or infirmity of nature, such an illusion is not to be feared, because it is rather to be lamented, that the mind of the person, who knew nothing of it, suffers the same, than that he occasioned it.

For there are some, who for the most part so suffer the illusion, that their mind, even during the sleep of the body, is not defiled with filthy thoughts. In which case, one thing is evident, that the mind is guilty even in its own judgment; for though it does not remember to have seen any thing whilst
