Ignatius of Antioch, Epistle to the Smyrnaeans 6.2
He suffered all these things for our sake, so that we might be saved. And he truly suffered, just as he truly raised himself. It is not as some faithless people say, that he suffered only in mere appearance. They themselves are unreal, and as they think, so it will happen to them, since they are bodiless and demonic.
Greek
Ταῦτα γὰρ πάντα ἔπαθεν δἰ ἡμᾶς, ἵνα σωθῶμεν: καὶ ἀληθῶς ἔπαθεν, ὡς καὶ ἀληθῶς ἀνέστησεν ἑαυτόν, οὐχ ὥσπερ ἄπιστοί τινες λέγουσιν, τὸ δοκεῖν αὐτὸν πεπονθέναι, αὐτοὶ το δοκεῖν ὄντες: καὶ καθὼς φρονοῦσιν, καὶ συμβήσεται αὐτοῖς, οὖσιν ἀσωμάτοις καὶ δαιμονικοῖς.
