Letter 46: Chrysostom says he loves Rufinus continually even when roads and season prevent frequent writing.

I wished to write more often to your Reverence, because I love you, and love you intensely, my most revered and devout master. You know both things yourself. But one thing is in our power and the other is not. We are masters of loving, but no longer masters of writing frequently, because of the difficult road and the season of the year. The one we do continually; the other, whenever possible. Or rather, we do that continually too. Even if we do not write continually with ink and paper, we write with mind and thought. Such is genuine love.

Μʹ. Ῥουφίνῳ. Ἐβουλόμην μὲν συνεχέστερον ἐπιστέλλειν σου τῇ εὐλαβείᾳ, ἐπειδή σε φιλῶ, καὶ σφόδρα φιλῶ, δέσποτά μου αἰδεσιμώτατε καὶ εὐλαβέστατε· καὶ ἀμφότερα ταῦτα οἶσθα καὶ αὐτός. Ἀλλ' ἐπειδὴ τὸ μὲν ἐν ἡμῖν κεῖται, τὸ δὲ οὐκ ἐν ἡμῖν· τοῦ μὲν γὰρ φιλεῖν ἡμεῖς κύριοι, τοῦ δὲ συνεχῶς ἐπιστέλλειν οὐκ ἔτι, διά τε τῆς ὁδοῦ τὴν δυσκολίαν, καὶ τοῦ ἔτους τὴν ὥραν· ἐκεῖνο μὲν διηνεκῶς ποιοῦμεν, τοῦτο δὲ ἡνίκα ἂν ἐξῇ· μᾶλλον δὲ καὶ τοῦτο διηνεκῶς ποιοῦμεν. Εἰ γὰρ καὶ μὴ μέλανι μηδὲ χάρτῃ συνεχῶς ἐπιστέλλομεν, ἀλλὰ γνώμῃ καὶ διανοίᾳ· τοιοῦτον γὰρ τὸ φιλεῖν γνησίως.
