1 Ἀγαπητοί, μὴ παντὶ πνεύματι πιστεύετε, ἀλλὰ δοκιμάζετε τὰ πνεύματα, εἰ ἐκ τοῦ θεοῦ ἐστίν· ὅτι πολλοὶ ψευδοπροφῆται ἐξεληλύθασιν εἰς τὸν κόσμον.
2 Ἐν τούτῳ
*⸂γινώσκεται⸃ τὸ πνεῦμα τοῦ θεοῦ· πᾶν πνεῦμα ὃ ὁμολογεῖ
*⸂
2Ἰησοῦν χριστὸν ἐν σαρκὶ ἐληλυθότα ἐκ τοῦ θεοῦ ἐστίν·
3 καὶ πᾶν πνεῦμα ὃ μὴ ὁμολογεῖ Ἰησοῦν χριστὸν ἐν σαρκὶ ἐληλυθότα,⸃ ἐκ τοῦ θεοῦ οὐκ ἔστιν· καὶ τοῦτό ἐστιν τὸ τοῦ ἀντιχρίστου, ὃ ἀκηκόατε ὅτι ἔρχεται, καὶ νῦν ἐν τῷ κόσμῳ ἐστὶν ἤδη.
4 Ὑμεῖς ἐκ τοῦ θεοῦ ἐστέ, τεκνία, καὶ νενικήκατε αὐτούς· ὅτι μείζων ἐστὶν ὁ ἐν ὑμῖν ἢ ὁ ἐν τῷ κόσμῳ.
5 Αὐτοὶ ἐκ τοῦ κόσμου εἰσίν· διὰ τοῦτο ἐκ τοῦ κόσμου λαλοῦσιν, καὶ ὁ κόσμος αὐτῶν ἀκούει.
6 Ἡμεῖς ἐκ τοῦ θεοῦ ἐσμέν· ὁ γινώσκων τὸν θεόν, ἀκούει ἡμῶν· ὃς οὐκ ἔστιν ἐκ τοῦ θεοῦ, οὐκ ἀκούει ἡμῶν. Ἐκ τούτου γινώσκομεν τὸ πνεῦμα τῆς ἀληθείας καὶ τὸ πνεῦμα τῆς πλάνης.
7 Ἀγαπητοί, ἀγαπῶμεν ἀλλήλους· ὅτι ἡ ἀγάπη ἐκ τοῦ θεοῦ ἐστίν, καὶ πᾶς ὁ ἀγαπῶν ἐκ τοῦ θεοῦ γεγέννηται, καὶ γινώσκει τὸν θεόν.
8 Ὁ μὴ ἀγαπῶν οὐκ ἔγνω τὸν θεόν· ὅτι ὁ θεὸς ἀγάπη ἐστίν.
9 Ἐν τούτῳ ἐφανερώθη ἡ ἀγάπη τοῦ θεοῦ ἐν ἡμῖν, ὅτι τὸν υἱὸν αὐτοῦ τὸν μονογενῆ ἀπέσταλκεν ὁ θεὸς εἰς τὸν κόσμον, ἵνα ζήσωμεν δι᾽ αὐτοῦ.
10 Ἐν τούτῳ ἐστὶν ἡ ἀγάπη, οὐχ ὅτι
*⸂ἡμεῖς ἠγαπήσαμεν τὸν θεόν, ἀλλ᾽ ὅτι αὐτὸς ἠγάπησεν ἡμᾶς,⸃ καὶ ἀπέστειλεν τὸν υἱὸν αὐτοῦ ἱλασμὸν περὶ τῶν ἁμαρτιῶν ἡμῶν.
11 Ἀγαπητοί, εἰ οὕτως ὁ θεὸς ἠγάπησεν ἡμᾶς, καὶ ἡμεῖς ὀφείλομεν ἀλλήλους ἀγαπᾷν.
12 Θεὸν οὐδεὶς πώποτε τεθέαται· ἐὰν ἀγαπῶμεν ἀλλήλους, ὁ θεὸς ἐν ἡμῖν μένει, καὶ ἡ ἀγάπη αὐτοῦ
*⸉τετελειωμένη ἐστὶν ἐν ἡμῖν.⸊
13 Ἐν τούτῳ γινώσκομεν ὅτι ἐν αὐτῷ μένομεν καὶ αὐτὸς ἐν ἡμῖν, ὅτι ἐκ τοῦ πνεύματος αὐτοῦ δέδωκεν ἡμῖν.
14 Καὶ ἡμεῖς τεθεάμεθα καὶ μαρτυροῦμεν ὅτι ὁ πατὴρ ἀπέσταλκεν τὸν υἱὸν σωτῆρα τοῦ κόσμου.
15 Ὃς
*⸂ἂν⸃ ὁμολογήσῃ ὅτι
*⸂
2Ἰησοῦς⸃ ἐστὶν ὁ υἱὸς τοῦ θεοῦ, ὁ θεὸς ἐν αὐτῷ μένει, καὶ αὐτὸς ἐν τῷ θεῷ.
16 Καὶ ἡμεῖς ἐγνώκαμεν καὶ πεπιστεύκαμεν τὴν ἀγάπην ἣν ἔχει ὁ θεὸς ἐν ἡμῖν. Ὁ θεὸς ἀγάπη ἐστίν, καὶ ὁ μένων ἐν τῇ ἀγάπῃ,
*⸂ἐν τῷ θεῷ μένει, καὶ ὁ θεὸς ἐν αὐτῷ μένει.⸃
17 Ἐν τούτῳ τετελείωται ἡ ἀγάπη μεθ᾽ ἡμῶν, ἵνα παρρησίαν ἔχωμεν ἐν τῇ ἡμέρᾳ τῆς κρίσεως, ὅτι καθὼς ἐκεῖνός ἐστιν, καὶ ἡμεῖς ἐσμὲν ἐν τῷ κόσμῳ τούτῳ.
18 Φόβος οὐκ ἔστιν ἐν τῇ ἀγάπῃ, ἀλλ᾽ ἡ τελεία ἀγάπη ἔξω βάλλει τὸν φόβον, ὅτι ὁ φόβος κόλασιν ἔχει· ὁ δὲ φοβούμενος οὐ τετελείωται ἐν τῇ ἀγάπῃ.
19 Ἡμεῖς
*⸂ἀγαπῶμεν αὐτόν, ὅτι αὐτὸς πρῶτος ἠγάπησεν ἡμᾶς.⸃
20 *⸂Ἐάν τις εἴπῃ ὅτι Ἀγαπῶ τὸν θεόν, καὶ τὸν ἀδελφὸν αὐτοῦ μισῇ,⸃ ψεύστης ἐστίν· ὁ γὰρ μὴ ἀγαπῶν τὸν ἀδελφὸν αὐτοῦ ὃν ἑώρακεν, τὸν θεὸν ὃν οὐχ ἑώρακεν
*⸂
2πῶς⸃ δύναται ἀγαπᾷν;
21 Καὶ ταύτην τὴν ἐντολὴν ἔχομεν ἀπ᾽ αὐτοῦ, ἵνα ὁ ἀγαπῶν τὸν θεόν, ἀγαπᾷ καὶ τὸν ἀδελφὸν αὐτοῦ.
