Ignatius of Antioch, Epistle to the Smyrnaeans 6.3
For I know and believe that he was in the flesh even after the resurrection.
And when he came to those around Peter, he said to them: "Take hold of me, touch me and see that I am not a bodiless demon." And immediately they touched him and believed, being joined to his flesh and his spirit. For this reason they also despised death, and they proved to be beyond death.
After the resurrection he ate and drank with them as one who is fleshly, even though he was spiritually united to the Father.
Greek
Ἐγὼ γὰρ καὶ μετὰ τὴν ἀνάστασιν ἐν σαρκὶ αὐτὸν οἶδα καὶ πιστεύω ὄντα.
καὶ ὅτε πρὸς τοὺς περὶ Πέτρον ἦλθεν, ἔφη αὐτοῖς: Λάβετε, ψηλαφήσατέ με καὶ ἴδετε, ὅτι οὐκ εἰμὶ δαιμόνιον ἀσώματον. καὶ εὐθὺς αὐτοῦ ἥψαντο καὶ ἐπίστευσαν, κραθέντες τῇ σαρκὶ αὐτοῦ καὶ τῷ πνεύματι. διὰ τοῦτο καὶ θανάτου κατεφρόνησαν, ηὑρέθησαν δὲ ὑπὲρ θάνατον.
μετὰ δὲ τὴν ἀνάστασιν συνέφαγεν αὐτοῖς καὶ συνέπιεν ὡς σαρκικός, καίπερ πνευματικῶς ἡνωμένος τῷ πατρί.
