A Greeting from the Elder
Ὁ πρεσβύτερος ἐκλεκτῇ κυρίᾳ καὶ τοῖς τέκνοις αὐτῆς οὓς ἐγὼ ἀγαπῶ ἐν ἀληθείᾳ, καὶ οὐκ ἐγὼ μόνος, ἀλλὰ καὶ πάντες οἱ ἐγνωκότες τὴν ἀλήθειαν,
The elder, To the chosen lady and her children, whom I love in the truth—and not I alone, but also all who know the truth—
διὰ τὴν ἀλήθειαν τὴν μένουσαν ἐν ἡμῖν, καὶ μεθ᾽ ἡμῶν ἔσται εἰς τὸν αἰῶνα·
because of the truth that abides in us and will be with us forever:
ἔσται μεθ᾽ ἡμῶν χάρις ἔλεος εἰρήνη παρὰ θεοῦ πατρὸς καὶ παρὰ Ἰησοῦ Χριστοῦ τοῦ υἱοῦ τοῦ πατρὸς ἐν ἀληθείᾳ καὶ ἀγάπῃ.
Grace, mercy, and peace from God the Father and from Jesus Christ, the Son of the Father, will be with us in truth and love.
Walking in the Truth
Ἐχάρην λίαν ὅτι εὕρηκα ἐκ τῶν τέκνων σου περιπατοῦντας ἐν ἀληθείᾳ καθὼς ἐντολὴν ἐλάβομεν παρὰ τοῦ πατρός.
I was overjoyed to find some of your children walking in the truth, just as the Father has commanded us.
καὶ νῦν ἐρωτῶ σε, κυρία, οὐχ ὡς ἐντολὴν καινὴν γράφων σοι, ἀλλ᾽ ἣν εἴχομεν ἀπ᾽ ἀρχῆς, ἵνα ἀγαπῶμεν ἀλλήλους.
And now I urge you, dear lady—not as a new commandment to you, but one we have had from the beginning—that we love one another.
καὶ αὕτη ἐστὶν ἡ ἀγάπη ἵνα περιπατῶμεν κατὰ τὰς ἐντολὰς αὐτοῦ. αὕτη ἡ ἐντολή ἐστιν καθὼς ἠκούσατε ἀπ᾽ ἀρχῆς, ἵνα ἐν αὐτῇ περιπατῆτε·
And this is love, that we walk according to His commandments. This is the very commandment you have heard from the beginning, that you must walk in love.
Beware of Deceivers
ὅτι πολλοὶ πλάνοι ἐξῆλθον εἰς τὸν κόσμον, οἱ μὴ ὁμολογοῦντες Ἰησοῦν Χριστὸν ἐρχόμενον ἐν σαρκί· οὗτός ἐστιν ὁ πλάνος καὶ ὁ ἀντίχριστος.
For many deceivers have gone out into the world, refusing to confess the coming of Jesus Christ in the flesh. Any such person is the deceiver and the antichrist.
βλέπετε ἑαυτοὺς ἵνα μὴ ἀπολέσητε ἃ εἰργασάμεθα, ἀλλὰ μισθὸν πλήρη ἀπολάβητε.
Watch yourselves, so that you do not lose what we have worked for, but that you may be fully rewarded.
πᾶς ὁ προάγων καὶ μὴ μένων ἐν τῇ διδαχῇ τοῦ Χριστοῦ θεὸν οὐκ ἔχει· ὁ μένων ἐν τῇ διδαχῇ οὗτος καὶ τὸν πατέρα καὶ τὸν υἱὸν ἔχει.
Anyone who runs ahead without remaining in the teaching of Christ does not have God. Whoever remains in His teaching has both the Father and the Son.
εἴ τις ἔρχεται πρὸς ὑμᾶς καὶ ταύτην τὴν διδαχὴν οὐ φέρει, μὴ λαμβάνετε αὐτὸν εἰς οἰκίαν, καὶ χαίρειν αὐτῷ μὴ λέγετε·
If anyone comes to you but does not bring this teaching, do not receive him into your home or even greet him.
ὁ λέγων γὰρ αὐτῷ χαίρειν, κοινωνεῖ τοῖς ἔργοις αὐτοῦ τοῖς πονηροῖς.
Whoever greets such a person shares in his evil deeds.
Conclusion
Πολλὰ ἔχων ὑμῖν γράφειν οὐκ ἐβουλήθην διὰ χάρτου καὶ μέλανος· ἀλλ᾽ ἐλπίζω γενέσθαι πρὸς ὑμᾶς καὶ στόμα πρὸς στόμα λαλῆσαι ἵνα ἡ χαρὰ ἡμῶν πεπληρωμένη ᾖ.
I have many things to write to you, but I would prefer not to do so with paper and ink. Instead, I hope to come and speak with you face to face, so that our joy may be complete.
