Matthew 28:16–17
You see how some of the evangelists run past certain things. For “they doubted” (Matthew 28:16–17) is clearly unfolded in John, where the one who doubted is shown — and he was Thomas. So mentioning the appearance in Judea that happened second also shows how the matter stood. But he said that he appeared to them in Galilee — which alone John seems to me to omit, since it lay before him to say the rest: how often he appeared, and where, and indeed how, narrating clearly (John 20:24–29).
Greek
Ὁρᾷς δὲ πῶς ἔνια παρατρέχουσί τινες τῶν εὐαγγελιστῶν· τὸ γὰρ ἐδίστασαν ἀνέπτυκται σαφῶς παρὰ τῷ Ἰωάννῃ δεικνυμένου τοῦ διστά σαντος, ὃς ἦν ὁ Θωμᾶς· ὥστε καὶ τὸ μνημονεῦσαι τῆς ἐν τῇ Ἰουδαίᾳ ἐπιφανείας δεύτερον γενομένης πῶς ἔσχε τὸ πρᾶγμα. εἶπεν δέ, ὅτι αὐτοῖς ὤφθη ἐν τῇ Γαλιλαίᾳ, ὃ μόνον δοκεῖ μοι Ἰωάννης παραλιπεῖν ὡς ἂν προκείμενον αὐτῷ τὰ λοιπὰ εἰπεῖν ὁσάκις τε ὤφθη καὶ ὅπου, ἀλλὰ μὴν καὶ ὅπως σαφῶς ἐξηγούμενος.
