(a) Despair is a greater sin than offenses against the moral virtues, for the chief inclination of despair is aversion from God, whereas the chief inclination of the latter kind of sins is conversion towards creatures. Thus, a person who drinks excessively does not primarily intend offense against God, but his own enjoyment or escape from certain worries.
(b) Despair in itself is less serious than the sins of unbelief and hatred of God; for, while despair is opposed to God as He is our good, the other two sins are opposed to God’s own truth and goodness.
(c) Despair is more serious than the sins of unbelief and hatred of God with reference to the danger it contains for the sinner; for it paralyzes effort and resists remedies: “Why is my sorrow become perpetual and my wound desperate, so as to refuse to be healed?” (Jer., xv. 18) “If thou lose hope, being weary in the day of distress, thy strength shall be diminished” (Prov., xxiv. 10). Despair is, therefore, a sin against the Holy Ghost, a sort of attempt at spiritual suicide. But (see 900) it is not unpardonable and may be overcome by divine grace.
1071. It is important to know the causes of despair, for this knowledge enables us to distinguish it from the mystical state known as “the dark night of the soul,” and to prescribe suitable remedies. Despair comes from one’s own fault, whereas mystical purgation from God is a preparation for a higher state of divine union. The causes of despair can be reduced to two, luxury and sloth.
(a) The secondary characteristic of a hopeful pursuit of heaven is courage, the adventurous spirit which foregoes ease and comfort for the sake of higher things, despising the danger and difficulty. Hence, the vice of lust, since it makes one love bodily delights and disregard or underestimate those that are spiritual, is a cause of despair, as well as of other sins opposed to the spiritual life (Gal., v. 17).
(b) The chief and most distinctive characteristic of hope is its cheerful confidence of success. Hence, the vice of sloth, since it is sadness weighing down the soul and making it unwilling to think rightly or to exert itself, is the principal cause of despair (Prov., xvii. 22).
1072. The apparent despair that is a trial to holy persons can be distinguished, therefore, from the sin of despair, especially by two signs: (a) though they are spiritually desolate and find no joy in religious practices, these persons do not turn to unlawful delights for consolation, but retain their dislike for lower pleasures; (b) though overcome with dismay at the thought of their own imperfection and of God’s holiness, they do not so lose heart as to give over their exercises of piety (cf. St. John of the Cross, _The Dark Night_, Bk. I, e. 9 ff.).
1073. Spiritual writers make the following recommendations for cases of spiritual desolation: (a) the afflicted persons should understand that the deprivation of former sensible devotion is a sign of God’s love and has been experienced by the Saints, and should, therefore, possess their souls in peace, leaving to God the time and manner of His heavenly visitation; (b) they should not burden themselves with new and heavier mortifications, lest they be overcome by too great sorrow, but should go on with their accustomed good works, and realize that, though bitter to them, these works are now all the more pleasing to God (Ibid., c. 10).
1074. Some Remedies for the Sin of Despair.—(a) If the cause is lust, one should learn that spiritual joys are nobler and more enduring than the joys of the flesh, and should take the means to sacrifice the lower in favor of the higher.
(b) If the cause of despair is spiritual sloth, one should meditate on the greatness of God’s power, mercy and love, and should avoid whatever fosters undue sadness, “lest he be swallowed up with over-much sorrow” (II Cor., ii. 7). Thus, those who are tormented by the thoughts of past sins or future temptations must subject their scruples to direction, and remember the mercy shown to the good thief, to Magdalene, and other penitents; those who have lost courage because they read spiritual books of a rigorous or terrifying nature, or have been advised to attempt that for which they were unsuited, should seek more prudent instruction and counsel; those who are naturally nervous or melancholy, should employ such therapeutical or preventive measures as are useful or necessary. All should follow the direction of St. Peter to labor the more, that by good works they may make sure their calling and election (II Pet., i. 10).
