Ignatius of Antioch, To the Ephesians 1.7
Some people, you see, have made a habit of carrying the name around with evil deceit while doing other things unworthy of God. You must shun them as you would wild beasts, for they are mad dogs that bite when you are not looking. Guard yourselves against them, because they are hard to heal.
There is one physician, both flesh and spirit, begotten and unbegotten, God in a human being, true life in death, both from Mary and from God, first subject to suffering and then beyond suffering: Jesus Christ our Lord.
Greek
Εἰώθασιν γάρ τινες δόλῳ πονηρῷ τὸ ὄνομα περιφέρειν, ἄλλα τινὰ πράσσοντες ἀνάξια θεοῦ: οὕς δεῖ ὑμᾶς ὡς θηρία ἐκκλίνειν: εἰσὶν γὰρ κύνες λυσσῶντες, λαθροδῆκται: οὓς δεῖ ὑμᾶς φυλάσσεσθαι ὄντας δυσθεραπεύτους.
εἷς ἰατρός ἐστιν, σαρκικός τε καὶ πνευματικός, γεννητὸς καὶ ἀγέννητος, ἐν ἀνθρώπῳ θεός, ἐν θανάτῳ ζωὴ ἀληθινή, καὶ ἐκ Μαρίας καὶ ἐκ θεοῦ, πρῶτον παθητὸς καὶ τότε ἀπαθής. Ἰησοῦς Χριστὸς ὁ κύριος ἡμῶν.
