God appears by measure and judgement
And do not be surprised if not all the crowds who have believed in Jesus see his resurrection, when Paul, writing to the Corinthians as to people who could not take in more, says: “I decided to know nothing among you except Jesus Christ, and him crucified” (1 Corinthians 2:2). Of the same kind is this saying too: “For you were not yet able; but even now you are still not able, for you are still fleshly” (1 Corinthians 3:2–3).
So the word, doing everything by divine judgement, has recorded of Jesus that before the passion he appeared to the many without distinction, and even this not always, but that after the passion he no longer showed himself in the same way, but with a certain judgement that measured out to each what was fitting. It is recorded that “God appeared to Abraham” (Genesis 12:7; compare 17:1; 18:1) or to one of the saints, and this “appeared” did not happen always but at intervals, nor did he appear to all. In just the same way, I ask you to understand that the Son of God also appeared by a judgement like the one by which God appeared to them.

Καὶ μὴ θαύμαζε, εἰ μὴ πάντες βλέπουσιν οἱ πεπιστευκότες ὄχλοι τῷ Ἰησοῦ τὴν ἀνάστασιν αὐτοῦ· ὅτε ὡς μὴ χωροῦσι πλείονα Κορινθίοις ὁ Παῦλος γράφων φησίν· „ἐγὼ δὲ ἔκρινα μηδὲν εἰδέναι ἐν ὑμῖν εἰ μὴ Ἰησοῦν Χριστὸν καὶ τοῦτον ἐσταυρωμένον.“ τοιοῦτον δέ ἐστι καὶ τό· „οὔπω γὰρ ἐδύνασθε· ἀλλ᾿ οὐδὲ ἔτι νῦν δύνασθε, ἔτι γὰρ σαρκικοί ἐστε.“ οὕτω τοίνυν πάντα κρίσει θείᾳ ποιῶν ὁ λόγος ἀνέγραψε περὶ τοῦ Ἰησοῦ, πρὸ μὲν τοῦ πάθους ἁπαξαπλῶς φανέντος τοῖς πλείοσι καὶ τοῦτο οὐκ ἀεὶ. μετὰ δὲ τὸ πάθος οὐκέτι ὁμοίως ἐπιφαινομένου ἀλλὰ μετά τινος κρίσεως ἑκάστῳ μετρούσης τὰ δέοντα. ὥσπερ δ᾿ ἀναγέγραπται τὸ „ὤφθη ὁ θεὸς τῷ Ἀβραὰμ“ ἤ τινι τῶν ἁγίων, καὶ τὸ „ὤφθη“ τοῦτο οὐκ ἀεὶ ἐγίνετο ἀλλ᾿ ἐκ διαλειμμάτων, καὶ οὐ πᾶσιν ἐφαίνετο· οὕτω μοι νόει καὶ τὸν υἱὸν τοῦ θεοῦ ὦφθαι τῇ παραπλησίᾳ περὶ ἐκείνων εἰς τὸ ὦφθαι αὐτοῖς τὸν θεὸν κρίσει.
