The Definition of Chalcedon in English, Greek, and Latin

The following is from the Christian Classics Ethereal Library.  The Definition of Chalcedon of A.D. 451 is given in English, Greek, and Latin.  This is the orthodox creed which defined how Jesus Christ could be both God and man incarnate.  While it is not a perfect confession or creed, it does help to reveal heresy when someone obviously rejects either the full humanity of Jesus or His complete deity.  Please note that any idea that the human nature is not "personal" is in effect to endorse Apollinarianism to one degree or another.  The Definition rules out Apollinarianism when it says that Jesus had a "reasonable soul".  In Greek this is "ἐκ ψυχῆς λογικῆς."

  

 English Translation

 We, then, following the holy Fathers, all with one consent, teach men to confess one and the same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a reasonable [rational] soul⁷² and body; consubstantial [coessential]⁷³ with the Father according to the Godhead, and consubstantial with us according to the Manhood; in all things like unto us, without sin; begotten before all ages of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the Virgin Mary, the Mother of God, according to the Manhood;⁷⁴ one and the same Christ, Son, Lord, Only-begotten, to be acknowledged in two natures,⁷⁵ inconfusedly, unchangeably,⁷⁶ indivisibly, inseparably;⁷⁷ the distinction of natures being by no means taken away by the union, but rather the property of each nature being preserved, and concurring in one Person and one Subsistence, not parted or divided into two persons, but one and the same Son, and only begotten, God the Word, the Lord Jesus Christ, as the prophets from the beginning [have declared] concerning him, and the Lord Jesus Christ himself has taught us, and the Creed of the holy Fathers has handed down to us.

Greek Translation

 Ἑπόμενοι τοίνυν τοῖς ἁγίοις πατράσιν ἕνα καὶ τὸν αὐτὸν ὁμολογεῖν υἱὸν τὸν κύριον ἡμῶν Ἰησοῦν Χριστὸν συμφώνως ἅπαντες ἐκδιδάσκομεν, τέλειον τὸν αὐτὸν ἐν θεότητι καὶ τέλειον τὸν αὐτὸν ἐν ἀνθρωπότητι, θεὸν ἀληθῶς καὶ ἄνθρωπον ἀληθῶς τὸν αὐτὸν, ἐκ ψυχῆς λογικῆς ⁶⁵ καὶ σώματος, ὁμοούσιον ⁶⁶ τῷ πατρὶ κατὰ τὴν θεότητα, καὶ ὁμοούσιον ⁶⁷ τὸν αὐτὸν ἡμῖν κατὰ τὴν ἀνθρωπότητα, κατὰ πάντα ὅμοιον ἡμῖν χωρὶς ἁμαρτίας· πρὸ αἰώνων μὲν ἐκ τοῦ πατρὸς γεννηθέντα κατὰ τὴν θεότητα, ἐπ᾽ ἐσχάτων δὲ τῶν ἡμερῶν τὸν αὐτὸν δἰ ἡμᾶς καὶ διὰ τὴν ἡμετέραν σωτηρίαν ἐκ Μαρίας τῆς παρθένου τῆς θεοτόκου κατὰ τὴν ἀνθρωπότητα ,⁶⁸ ἕνα καὶ τὸν αὐτὸν Χριστόν, υἱόν, κύριον, μονογενῆ, ἐκ δύο φύσεων [ἐν δύο φύσεσιν] ,⁶⁹ ἀσυγχύτως, ἀτρέπτως ,⁷⁰ ἀδιαιρέτως, ἀχωρίστως ⁷¹ γνωριζόμενον· οὐδαμοῦ τῆς τῶν φύσεων διαφορᾶς ἀνῃρημένης διὰ τὴν ἕνωσιν, σωζομένης δὲ μᾶλλον τῆς ἰδιότητος ἑκατέρας φύσεως καὶ εἰς ἓν πρόσωπον καὶ μίαν ὑπὸστασιν συντρεχούσης, οὐκ εἰς δύο πρόσωπα μεριζόμενον ἢ διαιρούμενον, ἀλλ᾽ ἕνα καὶ τὸν αὐτὸν υἱὸν καὶ μονογενῆ, θεὸν λόγον, κύριον Ἰησοῦν Χριστόν· καθάπερ ἄνωθεν οἱ προφῆται περὶ αὐτοῦ καὶ αὐτὸς ἡμᾶς ὁ κύριος Ιησοῦς Χριστὸς ἐξεπαίδευσε καὶ τὸ τῶν πατέρων ἡμῖν καραδέδωκε σύμβολον.

SYMBOLUM CHALCEDONENSE. VERSIO LATINA.

Sequentes igitur sanctos patres, unum eundemque confiteri Filium et Dominum nostrum Jesum Christum consonanter omnes docemus, eundem perfectum in deitate et eundem perfectum in humanitate; Deum verum et hominem verum eundem ex anima rationali et corpore; consubstantialem Patri secundum deitatem, consubstantialem nobis eundem secundum humanitatem; 'per omnia nobis similem, absque peccato' (Heb. iv.): ante secula quidem de Patre genitum secundum deitatem; in novissimis autem diebus eundem propter nos et propter nostram salutem ex Maria virgine, Dei genitrice secundum humanitatem; unum eundemque Christum, filium, Dominum, unigenitum, in duabus naturis inconfuse, immutabiliter, indivise, inseperabiliter agnoscendum: nusquam sublata differentia naturarum propter unitionem, magisque salva proprietate utriusque naturæ, et in unam personam atque subsistentiam concurrente: non in duos personas partitum aut divisum, sed unum eundemque Filium et unigenitum, Deum verbum, Dominum Jesum Christum; sicut ante prophetæ de eo et ipse nos Jesus Christus erudivit et patrum nobis symbolum tradidit.
