John Italos and the Eleven Chapters

The first great post-iconoclast addition to the Synodikon came in the late eleventh century, when the philosopher John Italos was tried and condemned; the chapters entered into the text on his account are the Church’s most explicit conciliar judgment on the limits of Hellenic philosophy inside Christian theology. This file narrates the two trials, sets out the chapters by content, and distinguishes what was condemned from what was not.

Tradition: Pan-Orthodox

The Man

John Italos was born around 1030 in Byzantine southern Italy — hence the sobriquet — and emigrated to Constantinople about 1050. He studied under Michael Psellos and succeeded him around 1076 as head of the imperially sponsored school of philosophy, holding the title hypatos tōn philosophōn, “consul of the philosophers.” He was a formidable dialectician with a combative temperament, admired and detested in roughly equal measure; he had earlier been accused of treason during a diplomatic mission to the Normans and pardoned (Stanford Encyclopedia of Philosophy, s.v. “John Italos,” Winter 2025 edition, on his life and career; Lowell Clucas, The Trial of John Italos and the Crisis of Intellectual Values in Byzantium in the Eleventh Century [Munich: Institut für Byzantinistik und Neugriechische Philologie der Universität München, 1981]).

The Two Trials

Italos was investigated twice.

1076/77. The first synodal investigation ended in his acquittal; the emperor intervened, though his reputation suffered (Stanford Encyclopedia of Philosophy, s.v. “John Italos”). The acts of the second trial are edited by Frederick Lauritzen as the Synod of 1082 in The Great Councils of the Orthodox Churches, ed. Alberto Melloni, vol. I (Turnhout: Brepols, 2016), 71–84 — the same volume that prints the critical text of the eleventh-century Synodikon into which the chapters were inserted.

March 1082. After Alexios I Komnenos took the throne in 1081, the case was reopened. An ecclesiastical synod at Constantinople examined Italos’ teaching — his Quaestiones quodlibetales among other writings — and found him guilty of heterodoxy in March 1082; he was compelled to withdraw from public life (SEP, s.v. “John Italos”; Lauritzen, ed., Synod of 1082, in The Great Councils, I, 71–84).

The charges concerned his dialectical method and his Platonic and Neoplatonic teaching: metempsychosis, the eternity of matter and of the Platonic ideas, positions on the resurrection body and the final restoration, and a rationalizing attitude toward the miracles of Christ and the saints. It should be said honestly that several of these charges “lack corroboration in his surviving writings,” and that modern scholarship — Clucas above all — has argued that the condemnation was in part politically motivated, serving the new Komnenian regime’s need to demonstrate orthodoxy (SEP, s.v. “John Italos,” on the mismatch between the charges and the extant works; Clucas, The Trial of John Italos, 1981, on the political dimension). [Disputed: whether the anathematized propositions accurately represent Italos’ own teaching is contested; Clucas (1981) treats the trial as substantially political, while the synodal acts and the Synodikon chapters record the propositions as the synod formulated them. What is not in dispute is what the Church condemned, which is what the Synodikon carries.]

The Chapters in the Synodikon

The received text of the Triodion heads this block “The Eleven Chapters against John Italus.” In the received English text ten chapters state propositions generically — “to them who…” — and an eleventh names Italos and his disciples. The Stanford Encyclopedia of Philosophy reports the same arithmetic from the other direction: ten articles condemning his teachings, “an eleventh personal condemnation” appearing in some manuscripts (SEP, s.v. “John Italos”). The chapters are not numbered individually here (METHODOLOGY §2); their content, in the order of the received text:

On those who attempt “by whatever means to introduce a new controversy or teaching into the ineffable Economy of our Incarnate Saviour and God,” seeking to penetrate the manner of the Word’s union with human substance and the reason for the deification of the assumed flesh, and using “dialectical terminology of nature and adoption” to dispute the innovation of His divine and human natures.
On those who “profess piety yet shamelessly, or rather impiously, introduce into the Orthodox and Catholic Church the ungodly doctrines of the Greeks concerning the souls of men, heaven and earth, and the rest of creation.”
On those who prefer “the foolish so-called wisdom of the secular philosophers” and accept “the metempsychosis of human souls,” or that the soul perishes like the beasts’, and so deny the resurrection, the judgment, and the final recompense.
On those who dogmatize “that matter and the Ideas are without beginning or are co-eternal with God,” and that heaven and earth are everlasting and immutable, “thus legislating contrary to Him Who said: ‘Heaven and earth shall pass away, but my words will not pass away.’”
On those who maintain that the wise men of the Greeks and the chief heresiarchs, though anathematized by the councils and the Fathers, are nevertheless “exceedingly more excellent, both here and in the future judgment, than those pious and orthodox men who, by human passion or by ignorance, have committed some offense.”
On those who do not accept “with a pure and simple faith and with all their soul and heart the extraordinary miracles of our Saviour and God and of the holy Theotokos… but who attempt by sophistic demonstration and words to traduce them as being impossible, or to misinterpret them according to their own way of thinking.”
On those who “undertake Greek studies not only for purposes of education but also follow after their vain opinions”, and are so convinced of their truth that they teach them to others, “sometimes secretly and sometimes openly.”
On those who “refashion creation by means of mythical fabrications and accept the Platonic ideas as veritable, saying that matter, being self-subsistent, is given form by these ideas,” thereby calumniating “the free will of the Creator Who brought all things into being out of non-being.”
On those who say that in the general resurrection men will be raised “in other bodies and not in those wherewith they passed this present life.”
On those who accept “the vain Greek teachings that there is a pre-existence of souls,” that all things were not made out of non-being, and “that there is an end to the torment or a restoration again of creation and of human affairs.”
On “those pagan and heterodox doctrines and teachings introduced in contempt of the Christian and Orthodox faith… by John Italus and by his disciples who shared in his ruin.”

What Was Condemned — and What Was Not

The seventh chapter is the one on which everything turns, and it is regularly misquoted. It does not anathematize the study of Greek philosophy. Its wording is precise: it falls on those who undertake Greek studies “not only for purposes of education but also follow after their vain opinions,” and are “so thoroughly convinced of their truth and validity” that they propagate them. The distinction drawn is between studying the Hellenic inheritance and believing it — between using philosophy as an instrument and receiving it as a doctrine.

That distinction is not an eleventh-century innovation. It is the settled patristic position, classically stated by St. Basil the Great in his address to young men on the profit to be had from Greek literature, and embodied by the whole Cappadocian generation, which was thoroughly educated in the schools and thoroughly unimpressed by their metaphysics (see St. Basil the Great; The Church Fathers). The Synodikon chapters ratify the patristic settlement conciliarly and liturgically; they do not reverse it.

The substantive condemnations, stripped of polemic, are these:

Against the pre-existence and transmigration of souls and against the annihilation of the soul — that is, against both the Platonist and the materialist alternatives to the Christian doctrine of the person created out of nothing and destined for resurrection (see Theological Anthropology).

Against the eternity of matter and of the Ideas — that is, in defense of creation ex nihilo by the free will of God. The chapter’s own reasoning names this: those who make matter self-subsistent “calumniate the free will of the Creator.”

Against the resurrection in a different body and against the apokatastasis understood as an end to the torment and a restoration of all — the chapter naming this a “vain Greek teaching” (see Orthodox Eschatology, where the history and status of this question in Orthodox theology is treated at length).

Against the rationalizing dissolution of miracle — not against the use of reason, but against the a priori that the miraculous must be explained away.

Against the subordination of the Church’s judgment to the prestige of the philosophers — the fifth chapter, which is really about authority: whether the Church’s anathema or the schools’ esteem settles who is to be honored.

Why This Mattered Enough to Enter the Synodikon

The Italos chapters mark a threshold. Before 1082 the Synodikon was a document about iconoclasm; after 1082 it is a document about Orthodoxy as such, capable of receiving the Church’s judgment on any dogmatic question. The Stanford Encyclopedia registers this precisely: the anti-Italos material constitutes “the first major addition” to the Synodikon in the cycle of updating that began in the eleventh century (SEP, s.v. “John Italos”).

Theologically, what the Church did in 1082 was to fix the relation between revelation and philosophical reason at the level of dogma. Byzantium had absorbed an enormous amount of Hellenic learning, and had done so deliberately; the eleventh century saw a genuine philosophical revival under Psellos and Italos. The condemnation did not end that revival — Byzantine philosophy continued, and Italos’ own students were active afterwards — but it declared that the results of philosophy are not premises of theology, and that where the two conflict the Church’s confession governs. The same principle would be invoked, in a different key, when Barlaam of Calabria applied philosophical criteria to the hesychasts two and a half centuries later; the Palamite councils explicitly accused their opponents of trying “once again to wickedly introduce into the Church of Christ the Platonic ideas and those other Greek myths” (Synodikon, received text, acclamation of St. Gregory Palamas — see The Palamite Chapters).

An Honest Ambivalence

Modern Orthodox readers are sometimes uncomfortable with the Italos chapters, and the discomfort deserves a hearing rather than a rebuke. The trial was entangled with the political needs of a new dynasty; some of the propositions may not represent what Italos actually held; and the chapters have occasionally been used to justify an anti-intellectualism that the Fathers themselves would not recognize.

Three things can be said in response without evasion. The chapters condemn propositions, and the propositions as formulated are genuinely incompatible with the Christian confession of creation, the person, and the resurrection — whoever held them. The seventh chapter, read as written, protects the study of philosophy while refusing its doctrines. And the Church’s judgment on the propositions does not depend on the justice of the proceedings against the man; a synod can be politically motivated and still condemn something that ought to be condemned. Where the historical question is genuinely open — whether Italos taught what he was said to teach — this collection reports the dispute and does not settle it (METHODOLOGY §4.2).
