De unione

Summary

De unione is a theological treatise attributed to John of Damascus, composed in the early 8th century, likely at the Monastery of Mar Saba. It addresses the union of natures in Christ, employing a dialectical style characteristic of late patristic polemic against Monophysitism. The work enumerates twelve modes of union, culminating in the hypostatic union, a key Chalcedonian doctrine. The Greek text survives in a single medieval manuscript tradition; the Khazarzar edition relies on printed editions without a critical apparatus, limiting its use for textual criticism. Attribution to John is traditional but not universally accepted, with some scholars suggesting it may be a compilation from his school. The treatise was influential in later Byzantine theology and cited in the Acts of the Council of Constantinople (680–681).

De unione is significant for its systematic taxonomy of modes of union, clarifying Chalcedonian Christology against Monophysite and Nestorian positions. It influenced later Byzantine theology and was cited at the Sixth Ecumenical Council. The work also illustrates the Damascene's method of synthesizing patristic tradition, though its disputed authorship raises questions about the extent of John's direct contribution.

Historical context

The work was composed in the early 8th century, during John of Damascus's tenure at the Monastery of Mar Saba in Palestine, a period of intense Christological debate following the Council of Chalcedon (451). The community was Greek-speaking and staunchly Chalcedonian, opposing Monophysitism and Nestorianism. The text survives in a single medieval manuscript tradition, with the Khazarzar edition based on printed editions that may introduce conjectural readings. Its transmission is tied to Byzantine theological circles, and it was cited in the Acts of the Council of Constantinople (680–681), indicating its early authority. The attribution to John is traditional but disputed; some scholars propose it may be a compilation from his school. The work's dialectical style and taxonomy of unions reflect late patristic polemical methods, engaging with earlier Christological debates.

Περὶ ἑνώσεως, τοῦ Δαμασκηνοῦ. Ἕνωσίς ἐστι διεστώτων πραγμάτων κοινωνικὴ συνδρομή. Γίνεται δὲ κατὰ ιβʹ τρόπους· κατὰ κρᾶσιν κατὰ σωρείαν, κατὰ φύσιν, κατὰ ἀνάμιξιν, κατὰ σύγχυσιν, κατὰ ἁρμονίαν, κατὰ παράθεσιν, κατὰ συναλοιφὴν, κατὰ οὐσίαν, κατὰ σχέσιν, κατὰ σύνθεσιν, καθ' ὑπό στασιν μόνως. Καὶ ἔστι κατὰ κρᾶσιν, ὡς ἐπὶ τῶν ὑγρῶν· οἴνου καὶ ὑδάτων. Κατὰ σωρείαν, ὡς ἐπὶ ξηρῶν· σίτου καὶ κριθῆς. Κατὰ φύρσιν, ὡς ἐπὶ ξηροῦ καὶ ὑγροῦ· γῆς καὶ ὕδατος. Κατὰ ἀνάμιξιν, ὡς ἐπὶ διαφόρων ἀλεύρων. Κατὰ σύγχυσιν, ὡς ἐπὶ τηκτῶν· χρυσοῦ καὶ ἀργύ ρου, κηροῦ καὶ πίσσης. Κατὰ ἁρμονίαν, ὡς ἐπὶ λίθων. Κατὰ παράθεσιν, ὡς ἐπὶ σανίδων. Κατὰ συναλοιφὴν, ὡς ἐπὶ λαμπάδος ἐκ πυρὸς προερχομένης καὶ αὖθις ἑνουμένης. Κατὰ οὐσίαν, ὡς ἐπὶ ἀτόμων, Πέτρου καὶ Παύλου, ἤ τινων ἵππων, ἢ βοῶν, ἢ ἑτέρων ζώων. Κατὰ σχέσιν, ὡς ἐπὶ φίλων καὶ γνωμῶν εἰς ἓν θέλημα συνερχομένων. Κατὰ σύνθεσιν, ὡς ἐπὶ ψυχῆς καὶ σώματος. Καθ' ὑπόστασιν δὲ ἐπὶ μόνης λέγεται τῆς ἐν Χρι στῷ θεότητος καὶ ἀνθρωπότητος. Ἓν γὰρ πρόσωπον ἔσχον αἱ δύο φύσεις, καὶ οὐ δύο, κατὰ τὸν λῆρον Νεστόριον. Λέγεται δὲ καὶ οὐσιώδης ἡ τοιαύτη ἕνωσις, καὶ ἀληθὴς, καὶ οὐ κατὰ φαντασίαν. Καὶ ἄλλως δὲ, καθ' ὑπόστασιν ἕνωσίς ἐστιν ἡ τῶν ἑτεροουσίων εἰς μίαν ὑπόστασιν σύνοδος, σωζομένης ἑκάστῳ μετὰ τὴν ἕνωσιν τῆς φυσικῆς ἰδιότητος.

English

On Union, by John of Damascus. Union is a common convergence of things that are separate. It occurs in twelve ways: by mixture, by heap, by nature, by blending, by fusion, by harmony, by juxtaposition, by coalescence, by essence, by relation, by composition, and by hypostasis alone. And it is by mixture, as in the case of liquids: wine and water. By heap, as in the case of dry things: wheat and barley. By nature, as in the case of dry and wet: earth and water. By blending, as in the case of different flours. By fusion, as in the case of meltable things: gold and silver, wax and pitch. By harmony, as in the case of stones. By juxtaposition, as in the case of planks. By coalescence, as in the case of a torch proceeding from fire and then being united again. By essence, as in the case of individuals: Peter and Paul, or certain horses, or oxen, or other animals. By relation, as in the case of friends and opinions coming together into one will. By composition, as in the case of soul and body. By hypostasis, however, it is said only of the divinity and humanity in Christ. For the two natures had one person, and not two, according to the nonsense of Nestorius. Such a union is also called substantial and true, and not imaginary. And otherwise, union by hypostasis is the convergence of things of different essences into one hypostasis, with each preserving its natural property after the union.

Commentary

termtextἝνωσις

The term 'Ἕνωσις' (union) is a central concept in Christological debates, distinct from mere mixture or juxtaposition, as John's taxonomy shows.

structuretext

The passage enumerates twelve modes of union, each with examples, culminating in the unique hypostatic union of Christ's two natures.

backgroundtextκαθ' ὑπόστασιν

The hypostatic union (καθ' ὑπόστασιν) is a key doctrine of Chalcedonian Christology, affirming one person in two natures, against Nestorianism.

receptiontextΝεστόριον

John dismisses Nestorius as 'λῆρον' (nonsense), reflecting the post-Ephesian condemnation and the Damascene's staunch orthodoxy.

cautiontextκατὰ φύσιν

The English draft translates 'κατὰ φύσιν' as 'by nature', but the Greek example (earth and water) suggests a mixture of dry and wet, not a natural union in the Aristotelian sense.

Open questions · 1

The Greek text lists twelve modes but the English draft omits 'κατὰ φύσιν' in the initial list, though it appears in the examples. The reading taken follows the Greek enumeration.
