Tertullian was the first Latin theologian and one of the most creative minds of the second and early third centuries. In particular, his writings contributed greatly to later articulations of the Trinity. This essay focuses on the negative, but not because I think Tertullian was worthless or because I think all good Protestants should bash the Fathers to prove their orthodoxy. On the contrary, we Protestants could probably use quite a bit more familiarity with, and appreciation for, the first five centuries of Christianity. It is precisely because of how much I enjoy Tertullian that his sub-biblical gospel stings me so sharply. I’m writing this because I think we Christians could benefit from understanding how this powerful theologian and apologist came to his misunderstanding of the gospel.
Tertullian believes that there are several unforgivable sins—“murder, idolatry, fraud, apostasy, blasphemy; (and), of course, too, adultery and fornication; and if there be any other ‘violation of the temple of God’” (On Modesty, 19). To Protestants, this alone appears unnecessarily harsh, but Tertullian goes farther still. It is not that the Church (or at least the New Prophets, i.e., Montanists) lacks the power to forgive these sins, in Tertullian’s view; it does have the power, but it ought not forgive such sins (On Modesty, 21). Disregarding Tertullian’s scriptural arguments, which are intriguing, his practical argument is that such leniency will simply encourage more sin in the Church, which is clearly unacceptable. There are a few hints that perhaps God in His mercy will forgive the repentant, but in any case, they cannot be returned to the fellowship of the Church.
What a twisted view of the gospel! Yet, it is more profitable to explain the context of this error than simply to decry it. We must start with Tertullian’s view of the Church. He is a perfectionist, or very nearly so. The Church is the bride of Christ, so no spot or blemish should be allowed in it. Anyone who could be condemned by the outside world on moral grounds should have already been cast out of the assembly (Apology, 44). Tertullian’s apologetic strategy both presupposes and necessitates this perfectionist tendency. Tertullian’s main argument for Christianity is the moral blamelessness of Christians. According to Tertullian, Christians simply don’t engage in bad behavior, at least nothing too bad. Although he does grant that Christians may need one (and only one) dose of post-baptismal forgiveness for some non-mortal sin (On Repentance, 7), Tertullian does not paint a picture of Christians struggling against sin, except in an unending stream of victories.
Tertullian’s view of the Christian life is intertwined with his beliefs concerning baptism and repentance. A sinner should not approach baptism carelessly, but with faith and firm repentance in hand (On Repentance, 6). As Eric Osborn summarizes, “We are not baptized so that we may stop sinning, but because we have stopped sinning” (Tertullian, 171). For Tertullian, baptism washes away sin and original sin. Osborne explains that Tertullian believes that the human soul, as created, was originally good and that that good part remains in man. Original sin forms a second nature, both different and lower (On the Soul, 16, 41), that veils or blocks out the higher nature so that it is rarely seen. Baptism, then, removes the veil and enables the repentant sinner to make good on his commitment to the new life (Tertullian, 166-7).
Using a similar picture, I think of Tertullian’s doctrine of salvation in terms of two window washers. One day, both washers look at their windows and notice how dirty and ugly they are, covered with filth and almost entirely opaque. Acknowledging the sordid condition of their windows and resolving to do better, they turn to their manager, who has more powerful cleaning tools than they possess. The manager comes out and cleans their windows for them until they are spotless, transparent. He shows them how to use the tools and charges them to keep their windows clean. If a few specks of dirt happen to get on the window, they can clean it, but if the window should ever again resemble its filthy state, that washer may as well leave his tools and go home.
Under this arrangement, the first washer cheerfully begins to keep his window clean. As he goes along, though, he keeps noticing spots that he missed, or that seem to be reappearing whenever he moves on to another part. He begins scrubbing faster, but in his carelessness he seems to miss more and more spots. The dirty looks from the other washer only unravel him more. In desperation, he appeals to his friend, “Your window looks so clean! Can’t you help me with mine?” The other washer barks out a derisive laugh. “Ha! Help you? We’ve been given the same opportunity, and look how well I’m doing. If you were really trying, surely you’d be doing better than that. I could help you, but if I helped every window washer who asked me, I’d only be encouraging laziness. As for you, I’d rather you just give up and go home. We’ll find someone else who can live up to being a window washer.” So the frustrated washer does go home, wondering how he could have been doing so poorly when that other washer did so well. Unbeknown to him, the successful washer had only kept his window so clean by ignoring the bottom two inches, which had become so crusted with grime that the casual observer wouldn’t even realize that portion was supposed to be part of the window.
Tertullian in his perfectionism fails to understand the extent of the law—lust is as adultery, hatred as murder—and the purpose of the law—to lead men to cast themselves on Christ. To Tertullian, his repentance is the moral resolve of an unregenerate man, and his regeneration through baptism effects only a second chance with better equipment. His attitude toward repentant sinners is that of a haughty “older brother” who thinks he always keeps the Father’s commands. Although I am deeply thankful for his work on the Trinity and Christ, and for his refutation of heretics, I must conclude that Tertullian misses the gospel.

Those who prefer grass roots revivalism have been more generous with Finney than many Calvinists would like. I will be more generous with both. Finney may be saved, and perhaps even Calvin, since salvation is by grace alone through faith alone alone in Christ alone. It is faith in the person of Christ that saves not having the detials all right on the atonement. Finney did have an effective soul winning ministry where lives were changed.. The abolitionist movement started with many Finney converts.
Joseph, when I wrote and submitted this, I knew that you were going to post almost exactly the response that you did. So, I'm not surprised, hurt, or shocked by it. In fact, I think you made a lot of great points about historical study. I will agree with you that my article is, to some extent, anachronistic. Any time one examines an aspect of a historical writer primarily to draw contemporary application, there is probably some anachronism. However, I will make at least a few points in my defense.
1. Assuming that the Protestant articulation of the gospel is indeed the biblical one, all Christians (indeed all people) bear some measure of responsibility for embracing it and ordering their lives in accordance with it. Tertullian's responsibility, due to his historical circumstances, is probably a lot less than those theologians' at the Council of Trent. However, if there is development in doctrine, it is from the human side only. God has not changed, developed, or even expanded what he means by the gospel. I think there is probably a measure of methodological impasse between us in this way.
2. I am addressing Tertullian in his historical context. During his lifetime, there was a running controversy over post-baptismal sins - which were "mortal," what you could do about them, how church leaders should address them, etc. Insofar as Tertullian chose the side in that debate that is farther from the biblical gospel, he expressed theological ideas that were contrary to gospel-informed reasoning, even by the standards of the early church.
3. My title and wording were deliberately ambiguous. As Aaron noted, genuine Christians can hold thoughts and attitudes contrary to the gospel. I think that people can be genuine believers with quite a few aberrations in their theology, even in their soteriology. However, expressing ideas that are out of accord with the gospel is very serious, and not the sort of thing that we can tolerate in ourselves or refuse to mark in others, even those early church Fathers living in a different era of "doctrinal development." I think the proper Protestant stance toward the church Fathers is somewhat ambiguous - heartfelt gratitude mixed with serious reservation.
