Discussion of theology is not for everyone, I tell you, not for everyone-it is no such inexpensive or effortless pursuit. Nor, I would add, is it for every occasion, or every audience; neither are all its aspects open to inquiry. It must be reserved for certain occasions, for certain audiences, and certain limits must be observed. It is not for all people, but only for those who have been tested and have found a sound footing in study, and, more importantly, have undergone, or at the very least are undergoing purification of body and soul. For one who is not pure to lay hold of pure things is dangerous, just as it is for weak eyes to look at the sun's brightness. What is the right time? Whenever we are free from the mire and noise without, and our commanding faculty is not confused by illusory, wandering images, leading us, as it were, to mix fine script with ugly scrawling, or sweet-smelling scent with slime. We need actually "to be still" in order to know God, and when we receive the opportunity, "to judge uprightly" in theology. Who should listen to discussions of theology? Those for whom it is a serious undertaking, not just another subject like any other for entertaining small-talk, after the races, the theater, songs, food, and sex: for there are people who count chatter on theology and clever deployment of arguments as one of their amusements. What aspects of theology should be investigated, and to what limit? Only aspects within our grasp, and only to the limit of the experience and capacity of our audience. Just as excess of sound or food injures the hearing or general health, or, if you prefer, as loads that are too heavy injure those who carry them, or as excessive rain harms the soil, we too must guard against the danger that the toughness, so to speak, of our discourses may so oppress and overtax our hearers as actually to impair the powers they had before.
As sinners we are like addicts - addicted to ourselves and our own projects. The theology of glory simply seeks to give those projects eternal legitimacy. The remedy for the theology of glory, therefore, cannot be encouragement and positive thinking, but rather the end of the addictive desire. Luther says it directly: "The remedy for curing desire does not lie in satisfying it, but in extinguishing it." So we are back to the cross, the radical intervention, end of the life of the old and the beginning of the new. Since the theology of glory is like addiction and not abstract doctrine, it is a temptation over which we have no control in and of ourselves, and from which we must be saved. As with the addict, mere exhortation and optimistic encouragement will do no good. It may be intended to build up character and self-esteem, but when the addict realizes the impossibility of quitting, self-esteem degenerates all the more. The alcoholic will only take to drinking in secret, trying to put on the facade of sobriety. As theologians of glory we do much the same. We put on a facade of religious propriety and piety and try to hide or explain away or coddle our sins.... As with the addict there has to be an intervention, an act from without. In treatment of alcoholics some would speak of the necessity of 'bottoming out,' reaching the absolute bottom where one can no longer escape the need for help. Then it is finally evident that the desire can never be satisfied, but must be extinguished. In matters of faith, the preaching of the cross is analogous to that intervention. It is an act of God, entirely from without. It does not come to feed the religious desires of the Old Adam and Eve but to extinguish them. They are crucified with Christ to be made new.
