Lactantius shares the “not received” shelf and a theology at least as irregular, yet keeps a mild memory: was the verdict on Tertullian uneven?

Related arguments: the comparative test — see also Hippolytus, the antipope who became a saint, Cyprian, wrong on rebaptism yet a saint, Novatian, whose shared rigorism became a schism, and the umbrella question, is it coherent to keep his theology while withholding his name?

Type: supporting argument (off-timeline, a comparative test) · Assessment: contested — Lactantius of Nicomedia (c. 250–c. 325), the “Christian Cicero,” shares with Tertullian a single distinction: the same anonymous sixth-century book-list, the Decretum Gelasianum, that placed “the works of Tertullian” among the apocrypha, the writings “not received,” placed “the works of Lactantius” on the very next line of the same shelf. And on the doctrinal axis Lactantius’s theology is at least as irregular as Tertullian’s — a pre-Nicene subordination of the Son, a startling pairing of Christ and the devil as God’s elder and younger “sons,” an outright denial (on Jerome’s report) of the distinct subsistence of the Holy Spirit, and the same literal earthly millennium. Jerome, who supplied the damning “lapsed” of Tertullian, was no gentler on Lactantius: “would that he had been as ready to teach our doctrines as he was to pull down those of others.” Yet where Tertullian is the standing Latin byword for the heretic — a numbered entry in Augustine’s handbook, a sect named after him, a lament from Vincent — Lactantius draws no anathema, no heresy-catalogue entry, no schism bearing his name, and posterity crowns him the “Christian Cicero.” Same shelf, comparable (arguably graver) irregularity, far softer memory. The interpretation weighed here is that the comparison isolates the real driver of the “heretic” label: not doctrinal irregularity as such — Lactantius has that in full and escapes — but the Montanist affiliation, the assault on the church’s discipline and its bishops, and the reported schism, which Lactantius wholly lacks. As an isolation of that variable it is strong. As a charge that Tertullian was therefore treated unfairly it is weaker, because the very disanalogies are the principled explanation, and because the church did to Lactantius exactly what it did to Tertullian — quarry the usable, quietly decline the rest. Contested.

This is not a count any ancient source laid against Tertullian: no synod, no heresy-catalogue, and not Augustine’s notice among the heresies ever faults him by comparison with Lactantius. It belongs, like the Hippolytus, Cyprian, and Novatian comparanda, not to the reckoning of the counts but to the prior question the whole timeline of the verdict keeps returning to: what, exactly, was he faulted for, and was the verdict even? Here the case set beside Tertullian runs a third way. The two saints show a graver or comparable fault forgiven a man reconciled and martyred; Novatian shows the shared rigorism branded once a rival church was added to it. Lactantius shows something the others cannot: a father whose doctrine was as irregular as Tertullian’s, who shared his place on the rejected shelf — and who was never called a heretic at all. He isolates the variable from the doctrinal side. If irregular theology alone made the heretic, Lactantius would wear the title too; he does not, so it was something else.¹

The same shelf: two fathers “not received”

The one formal Roman-looking mark against Tertullian is not a synod or an anathema but a book-list: the so-called Decretum Gelasianum, a register “of books to be received and not received,” which the main timeline shows to be neither papal nor Gelasian but an anonymous private compilation of the earlier sixth century. Its fifth part opens, “The remaining writings which have been compiled or been recognised by heretics or schismatics the Catholic and Apostolic Roman Church does not in any way receive,” and then runs down a column of authors whose opuscula are stamped, one after another, apocrypha. Two entries stand side by side: opuscula Tertulliani apocrypha — “the works of Tertullian, apocryphal” — and opuscula Lactantii sive Firmiani apocrypha — “the works of Lactantius, also called Firmianus, apocryphal.” Tertullian and Lactantius keep company on that shelf with Arnobius, Africanus, Commodian, Cassian, Victorinus of Pettau, the other Clement of Alexandria, and — the paradox at its sharpest — the martyr-bishop Cyprian.²

So on the one documentary act that could be mistaken for an official Roman verdict, Tertullian and Lactantius are treated identically: both refused, in the same clause, by the same anonymous hand. Whatever that list is worth — and it is worth little as law, being a scholar’s handbook later ages wrongly thought a decree — it is worth exactly the same against each of them. The rejected shelf does not distinguish the heresiarch from the Christian Cicero. If the later tradition came to distinguish them sharply, it did so on some ground other than this shared and official-looking censure.³

A theology at least as irregular

Set the doctrine of the two men beside each other and it is not clear that Tertullian’s is the more suspect. On the count for which Tertullian is most often arraigned in retrospect — the subordination of the Son — Lactantius stands with him, ranking the Son below the Father in the shared ante-Nicene idiom that the whole age spoke before the councils fixed the terms. But Lactantius carries irregularity into places Tertullian never went. In the Divine Institutes he explains the origin of good and evil by a startling pairing: before making the world God “produced a Spirit like to Himself, who might be endowed with the perfections of God the Father” — “that first and greatest Son” — and “then He made another being, in whom the disposition of the divine origin did not remain,” who “was infected with his own envy as with poison, and passed from good to evil.” The two are set out as a matched pair, an elder son who kept the Father’s goodness and a younger who fell from it — so that the devil appears, in shape of speech, almost as God’s second son. It is language a later, more precise age found disturbing, and it is a good deal stranger than anything in Tertullian’s Trinity.⁴

On the Holy Spirit, Lactantius is charged by Jerome himself with a plain error Tertullian never committed. Where Tertullian is the father of the Latin trinitas and wrote the West’s first great defence of the three Persons, Lactantius, in Jerome’s report, “in his books and particularly in his letters to Demetrian altogether denies the subsistence of the Holy Spirit, and following the error of the Jews says that the passages in which he is spoken of refer to the Father or to the Son.” And in eschatology the two are simply alike: Lactantius devotes the last book of the Institutes to a literal earthly millennium — the world lasting six thousand years, then the resurrection of the righteous and their thousand-year reign with Christ — the same chiliasm weighed, for Tertullian, on its own page. Subordinationism they share; the two-“sons” scheme and the denial of the Spirit’s subsistence are Lactantius’s alone, and both cut nearer the creed than the corporealism that is the gravest doctrinal charge anyone ever actually laid on Tertullian — and which Augustine expressly declined to make the ground of a heresy.⁵

Nor is this a distinction only hindsight can see. Jerome, the very writer whose one verb — lapsus est, “he lapsed” — hung the heretic’s frame on Tertullian, judged Lactantius no more affirmatively sound. In the letter to Paulinus he grants the eloquence and withholds the doctrine: “Lactantius has a flow of eloquence worthy of Tully: would that he had been as ready to teach our doctrines as he was to pull down those of others.” It is, in substance, the same verdict Vincent of Lérins passed on Tertullian — “more eloquent by far than faithful” — delivered by the same hostile pen. Two fathers, then, whom Jerome reckoned better at demolition than at construction, both stamped apocryphal by the same list. The doctrinal case against Lactantius is, if anything, the heavier of the two.⁶

Yet the memory is mild

Here the cases part, and the parting is the argument’s point. Everything that turned Tertullian into the standing Latin example of the heretic is, in Lactantius’s case, missing. There is no numbered entry among the heresies: Augustine, who gave Tertullian chapter 86 of the De haeresibus, catalogues no “Lactantian” error. There is no sect: no ancient writer reports a body of “Lactantians” with a basilica of their own, as Augustine reports the Tertullianistae. There is no lament held up to students, as Vincent held up Tertullian beside Origen. There is not even the charge of heresy in the abstract. Lactantius drew the quiet non-reception of the book-list and Jerome’s cool remark about his doctrine — and nothing more. Where Tertullian’s name became a warning, Lactantius’s became an honour: the “Christian Cicero,” the model of Latin Christian style, prized by the humanists and printed at the dawn of printing.⁷

So the two men converge on the one point where a formal verdict might be looked for — the rejected shelf — and diverge on everything softer and more lasting: the catalogue, the sect, the lament, the tone of the tradition’s memory. The variable that produced the divergence cannot be the doctrine, since by that measure Lactantius, not Tertullian, carries the heavier load. It must be found in what Tertullian did and Lactantius did not.⁸

What the comparison isolates

What Tertullian did, and Lactantius did not, is threefold, and all three lie on the axis of affiliation and church order, not doctrine. Tertullian went over to the New Prophecy, a movement the church had condemned as false prophecy, and made its Paraclete a still-speaking authority binding on the whole church. He turned that authority against the bishops, setting “the Church of the Spirit… not the Church which consists of a number of bishops” over the hierarchy and mocking the “bishop of bishops.” And on the reports he ended in a rigorist splinter of his own, the Tertullianistae. Lactantius did none of these. He joined no prophetic sect and claimed no new revelation; his errors are those of a solitary apologist reasoning his own way, not a party’s tenets. He never set a “Church of the Spirit” against the bishops or attacked the church’s discipline; his quarrel was with the pagans, not the clergy. And he founded nothing — no sect bears his name. His irregular theology sat quietly inside an unquestioned churchmanship, and so it drew no brand.⁹

That is the comparison’s real yield, and it corroborates the capstone from a fresh angle. The Hippolytus and Cyprian cases show that a grave fault is forgiven a man reconciled and martyred; the Novatian case shows that a shared rigorism is branded once a rival church is added to it. Lactantius adds the control the others lack: a man with the irregular doctrine but without the affiliation, the assault on order, or the schism — and he goes unbranded. Taken together the four cases converge on one finding: the “heretic” verdict on a Father tracks his sect, his stance toward the church’s authority, the manner of his death, and the fortunes of his name far more than the bare content of his doctrine. That is the doctrine-or-discipline question answered from outside Tertullian’s own case: what made him a heretic was not, in the end, what he taught.¹⁰

But the disanalogies are principled — and Lactantius was filtered too

Here the charge of unfairness meets the same reply that blunts the two-saints comparanda, and it lands harder. The three things Tertullian did and Lactantius did not are not trivial makeweights; they are exactly the church’s stated grounds for the verdict. Augustine, cataloguing Tertullian, rests the heresy not on the corporealism but on the turn to the Cataphrygians, the ban on second marriage, and the splinter — that is, on the affiliation, the assault on discipline, and the schism. A verdict that turns on those, and passes over a man who committed none of them, is not applying an uneven standard; it is applying its own standard evenly. Lactantius’s milder memory is thus explained, not merely contrasted: he escaped the brand because he did the things the brand actually tracks — joining a condemned sect, attacking the bishops, breaking communion — none of them. On the comparison’s own showing, the difference between the two men is real and principled, which is precisely what a charge of caprice needs to deny.¹¹

Two further qualifications keep the comparison honest. First, the “same shelf” spine, though secure in the received text of the Decretum, is not quite unanimous: in his critical edition von Dobschütz noted a group of later witnesses that omit Lactantius and read only “the works of Tertullian, or of Africanus, apocryphal” — so the Lactantius entry, while the majority reading, rests on the main manuscript tradition rather than on every copy. Second, and more telling, the church did to Lactantius the very thing it did to Tertullian: it kept what was usable and quietly let the rest lie. Lactantius’s eloquence and his apologetic were mined for centuries even as his two-“sons” scheme and his denial of the Spirit were passed over in embarrassed silence — the same “keep the teaching, drop the error” operation the capstone weighs, now applied to a man never condemned. That the two fathers were handled by the same discriminating method, not two different standards, cuts against the picture of an uneven verdict. The church did not read Tertullian more harshly than Lactantius; it read both selectively, and named as a heretic only the one who added a sect and a schism to his irregular pages.¹²

One limit runs the other way, and honesty requires it. A steelman of Lactantius’s doctrine narrows the “at least as irregular” claim at one point: his two “sons” are not a metaphysical dualism. The devil, in his telling, is a creature made good who fell by his own will, not a second, co-eternal principle of evil — so the scheme is startling in its wording, and was rightly found so, but monist at its root, evil remaining derived and voluntary. That keeps his irregularity from being heresy in the strict sense, which is fair to Lactantius. But it does not rescue the objection, for it applies with equal force to Tertullian, whose subordinationism and corporealism the same steelmanning defence reads as ante-Nicene idiom rather than heresy. Both men, read charitably, are irregular-but-not-heretical in doctrine; the asymmetry in their memory therefore still owes nothing to doctrine — which is the comparison’s point, surviving even its own best qualification.¹³

Adversarial assessment

What holds. The historical core is secure and rests on no disputed reconstruction. That Tertullian and Lactantius share the Decretum’s rejected shelf is the plain reading of the list (with only a minority variant against it). That Lactantius’s theology is at least as irregular as Tertullian’s is documented from the primary texts — the two-“sons” scheme of Divine Institutes II, the millennium of Book VII, and, on the Holy Spirit, Jerome’s own charge that Lactantius “altogether denies the subsistence” of the third Person. That Jerome judged him doctrinally deficient is his letter to Paulinus in as many words. And that Lactantius nonetheless drew no anathema, no catalogue entry, no sect, and no lament, while keeping an honoured memory, is simply the record. As an isolation of the variable the comparative test is after — that the verdict tracks affiliation, church order, and the fortunes of a name more than the content of the doctrine — Lactantius is as strong as any of the four cases and uniquely clean, since he adds the missing control: irregular doctrine without the sect or the schism, and no brand.

But it does not show the verdict was unfair. The divergence the comparison exposes is exactly what the church said its verdict tracked: Augustine founds Tertullian’s heresy on the Montanism, the rigorist novelty, and the schism, not on his doctrine — and Lactantius committed none of the three. To pass over the man who did none of them and brand the man who did all of them is an even application of a stated standard, not a double one. The disanalogies are therefore principled, not arbitrary: Lactantius joined no condemned sect, claimed no binding new revelation, never set the Spirit’s church against the bishops, and founded nothing. And the church handled both fathers by the same selective method — keep the usable, let the rest lie — so the difference in their memory reflects the difference in their conduct, not two standards.

Where the comparison keeps its force. What survives every qualification is the negative finding, and it is the one the whole comparative test converges on. Doctrinal irregularity, by itself, did not make the heretic — Lactantius proves it, carrying as much and escaping the title. So the label on Tertullian cannot be read as a verdict on his theology; whatever it condemns, it condemns his sect, his stance toward the church’s order, and (on the reports) his schism. That both narrows the doctrinal charge against Tertullian and denies the objection its sharpest form: the verdict was about something real — affiliation and church order — and by that measure it was applied to him, and withheld from Lactantius, consistently.

Assessment

contested. Lactantius is the comparative test’s control case: a father whose doctrine was at least as irregular as Tertullian’s — a subordinated Son, a devil paired as God’s second “son,” a denied subsistence of the Spirit, a literal millennium — who shared his exact place on the Decretum’s rejected shelf and drew Jerome’s same verdict of eloquence-without-doctrine, yet was never called a heretic, never catalogued, never made a sect’s eponym, and is remembered as the “Christian Cicero.” As an isolation of the variable it is strong and exceptionally clean, corroborating the capstone from the side the honoured saints and the condemned schismatic cannot reach: irregular doctrine minus the sect and the schism yields no brand, so the brand never tracked the doctrine. As a charge that Tertullian was treated unfairly it does not carry: the very things Lactantius lacked — the Montanist affiliation, the assault on the bishops, the splinter — are the church’s own stated grounds for the verdict, so the softer memory of Lactantius is the same standard applied evenly, not a different one; and the church filtered Lactantius by the identical “keep the teaching, drop the error” method it used on Tertullian. Strong by the light of what it reveals about how such verdicts form, weak by the light of the unfairness it is sometimes made to allege. Contested.
