The Shortest Letter with the Biggest Warning.

Ὁ πρεσβύτερος ἐκλεκτῇ κυρίᾳ καὶ τοῖς τέκνοις αὐτῆς, οὓς ἐγὼ ἀγαπῶ ἐν ἀληθείᾳ, καὶ οὐκ ἐγὼ μόνος ἀλλὰ καὶ πάντες οἱ ἐγνωκότες τὴν ἀλήθειαν,

[1] The elder to the elect lady and her children, whom I love in truth, and not only I, but also all who know the truth,

διὰ τὴν ἀλήθειαν τὴν μένουσαν ἐν ἡμῖν, καὶ μεθ’ ἡμῶν ἔσται εἰς τὸν αἰῶνα·

[2] because of the truth that abides in us and will be with us forever:

ἔσται μεθ’ ἡμῶν χάρις ἔλεος εἰρήνη παρὰ θεοῦ πατρός, καὶ παρὰ Ἰησοῦ Χριστοῦ τοῦ υἱοῦ τοῦ πατρός, ἐν ἀληθείᾳ καὶ ἀγάπῃ.

[3] Grace, mercy, and peace will be with us, from God the Father and from Jesus Christ the Father's Son, in truth and love.

Ἐχάρην λίαν ὅτι εὕρηκα ἐκ τῶν τέκνων σου περιπατοῦντας ἐν ἀληθείᾳ, καθὼς ἐντολὴν ἐλάβομεν παρὰ τοῦ πατρός.

[4] I rejoiced greatly to find some of your children walking in the truth, just as we were commanded by the Father.

καὶ νῦν ἐρωτῶ σε, κυρία, οὐχ ὡς ἐντολὴν καινὴν γράφων σοι ἀλλὰ ἣν εἴχομεν ἀπ’ ἀρχῆς, ἵνα ἀγαπῶμεν ἀλλήλους.
