"1. This book, wherein Teresa of Jesus, Carmelite nun, and foundress of the Barefooted Carmelites, gives a plain account of the state of her soul, in order to be taught and directed by her confessors, has been examined by me, and with much attention, and I have not found anywhere in it anything which, in my opinion, is erroneous in doctrine. On the contrary, there are many things in it highly edifying and instructive for those who give themselves to prayer. The great experience of this religious, her discretion also and her humility, which made her always seek for light and learning in her confessors, enabled her to speak with an accuracy on the subject of prayer that the most learned men, through their want of experience, have not always attained to. One thing only there is about the book that may reasonably cause any hesitation till it shall be very carefully examined; it contains many visions and revelations, matters always to be afraid of, especially in women, who are very ready to believe of them that they come from God, and to look on them as proofs of sanctity, though sanctity does not lie in them. On the contrary, they should be regarded as dangerous trials for those who are aiming at perfection, because Satan is wont to transform himself into an angel of light, [23] and to deceive souls which are curious and of scant humility, as we have seen in our day: nevertheless, we must not therefore lay down a general rule that all revelations and visions come from the devil. If it were so, St. Paul could not have said that Satan transforms himself into an angel of light, if the angel of light did not sometimes enlighten us. "2. Saints, both men and women, have had revelations, not only in ancient, but also in modern times; such were St. Dominic, St. Francis, St. Vincent Ferrer, St. Catherine of Siena, St. Gertrude, and many others that might be named; and as the Church of God is, and is to be, always holy to the end, not only because her profession is holiness, but because there are in her just persons and perfect in holiness, it is unreasonable to despise visions and revelations, and condemn them in one sweep, seeing they are ordinarily accompanied with much goodness and a Christian life. On the contrary, we should follow the saying of the Apostle in 1 Thess. v. 19-22: 'Spiritum nolite extinguere. Prophetias nolite spernere. Omnia [autem] probate: quod bonum est tenete. Ab omni specie mala abstinete vos.' He who will read St. Thomas on that passage will see how carefully they are to be examined who, in the Church of God, manifest any particular gift that may be profitable or hurtful to our neighbour, and how watchful the examiners ought to be lest the fire of the Spirit of God should be quenched in the good, and others cowed in the practices of the perfect Christian life.
