5 This happens because the actual possession by the spirit of one of two contrary things itself makes impossible the actual possession and realization of the other contrary thing; this is not so, however, in the sensual part of the soul, because its apprehension is weak. But, as the spirit is not yet completely purged and cleansed from the affections that it has contracted from its lower part, while changing not in so far as it is spirit, it can be moved to further afflictions in so far as these affections sway it. In this way, as we see, David was afterwards moved, and experienced many ills and afflictions, although in the time of his abundance he had thought and said that he would never be moved. Just so is it with the soul in this condition, when it sees itself moved by that abundance of spiritual blessings, and, being unable to see the root of the imperfection and impurity which still remain within it, thinks that its trials are over.
6. This thought, however, comes to the soul but seldom, for, until spiritual purification is complete and perfected, the sweet communication is very rarely so abundant as to conceal from the soul the root which remains hidden, in such a way that the soul can cease to feel that there is something that it lacks within itself or that it has still to do. Thus it cannot completely enjoy that relief, but feels as if one of its enemies were within it, and although this enemy is, as it were, hushed and asleep, it fears that he will come to life again and attack it.133133[Lit., ‘and play his tricks upon it.’] And this is what indeed happens, for, when the soul is most secure and least alert, it is dragged down and immersed again in another and a worse degree of affliction which is severer and darker and more grievous than that which is past; and this new affliction will continue for a further period of time, perhaps longer than the first. And the soul once more comes to believe that all its blessings are over for ever. Although it had thought during its first trial that there were no more afflictions which it could suffer, and yet, after the trial was over, it enjoyed great blessings, this experience is not sufficient to take away its belief, during this second degree of trial, that all is now over for it and that it will never again be happy as in the past. For, as I say, this belief, of which the soul is so sure, is caused in it by the actual apprehension of the spirit, which annihilates within it all that is contrary to it.
7. This is the reason why those who lie in purgatory suffer great misgivings as to whether they will ever go forth from it and whether their pains will ever be over. For, although they have the habit of the three theological virtues—faith, hope and charity—the present realization which they have of their afflictions and of their deprivation of God allows them not to enjoy the present blessing and consolation of these virtues. For, although they are able to realize that they have a great love for God, this is no consolation to them, since they cannot think that God loves them or that they are worthy that He should do so; rather, as they see that they are deprived of Him, and left in their own miseries, they think that there is that in themselves which provides a very good reason why they should with perfect justice be abhorred and cast out by God for ever.134134 B. Bz., C, H. Mtr. all have this long passage on the suffering of the soul in Purgatory. It would be rash, therefore, to deny that St. John of the Cross is its author, [or to suppose, as P. Gerardo did, that he deleted it during a revision of his works]. An admirably constructed synthesis of these questions will be found in B. Belarmino, De Purgatorio, Bk. II, chaps. iv, v. He asks if souls in Purgatory are sure of their salvation. This was denied by Luther, and by a number of Catholic writers, who held that, among the afflictions of these souls, the greatest is this very uncertainty, some maintain that, though they have in fact such certainty, they are unaware of it. Belarmino quotes among other authorities Denis the Carthusian De quattuor novissimis, Gerson (Lect. I De Vita Spirituali) and John of Rochester (against Luther’s 32nd article); these writers claim that, as sin which is venial is only so through the Divine mercy, it may with perfect justice be rewarded by eternal punishment, and thus souls that have committed venial sin cannot be confident of their salvation. He also shows, however, that the common opinion of theologians is that the souls in Purgatory are sure of their salvation, and considers various degrees of certainty, adding very truly that, while these souls experience no fear, they experience hope, since they have not yet the Beatific vision.
Uncertainty as to their salvation, it is said, might arise from ignorance of the sentence passed upon them by the Judge or from the deadening of their faculties by the torments which they are suffering. Belarmino refutes these and other suppositions with great force and effect. St. John of the Cross seems to be referring to the last named when he writes of the realization of their afflictions and their deprivation of God not allowing them to enjoy the blessings of the theological virtues. It is not surprising if the Saint, not having examined very closely this question, of which he would have read treatments in various authors, thought of it principally as an apt illustration of the purifying and refining effects of passive purgation; and an apt illustration it certainly is. And thus although the soul in this purgation is conscious that it has a great love for God and would give a thousand lives for Him (which is the truth, for in these trials such souls love their God very earnestly), yet this is no relief to it, but rather brings it greater affliction. For it loves Him so much that it cares about naught beside; when, therefore, it sees itself to be so wretched that it cannot believe that God loves it, nor that there is or will ever be reason why He should do so, but rather that there is reason why it should be abhorred, not only by Him, but by all creatures for ever, it is grieved to see in itself reasons for deserving to be cast out by Him for Whom it has such great love and desire.
