Ἀγαπητοί, μὴ παντὶ πνεύματι πιστεύετε, ἀλλὰ δοκιμάζετε τὰ πνεύματα, εἰ ἐκ τοῦ Θεοῦ ἐστιν, ὅτι πολλοὶ ψευδοπροφῆται ἐξεληλύθασιν εἰς τὸν κόσμον.
Ἐν τούτῳ γινώσκετε τὸ Πνεῦμα τοῦ Θεοῦ: πᾶν πνεῦμα ὃ ὁμολογεῖ Ἰησοῦν Χριστὸν ἐν σαρκὶ ἐληλυθότα, ἐκ τοῦ Θεοῦ ἐστιν,
καὶ πᾶν πνεῦμα ὃ μὴ ὁμολογεῖ τὸν Ἰησοῦν, ἐκ τοῦ Θεοῦ οὐκ ἔστιν. Καὶ τοῦτό ἐστιν τὸ τοῦ ἀντιχρίστου, ὃ ἀκηκόατε ὅτι ἔρχεται, καὶ νῦν ἐν τῷ κόσμῳ ἐστὶν ἤδη.
Ὑμεῖς ἐκ τοῦ Θεοῦ ἐστε, τεκνία, καὶ νενικήκατε αὐτούς, ὅτι μείζων ἐστὶν ὁ ἐν ὑμῖν, ἢ ὁ ἐν τῷ κόσμῳ.
Αὐτοὶ ἐκ τοῦ κόσμου εἰσίν· διὰ τοῦτο ἐκ τοῦ κόσμου λαλοῦσιν, καὶ ὁ κόσμος αὐτῶν ἀκούει.
Ἡμεῖς ἐκ τοῦ Θεοῦ ἐσμεν. Ὁ γινώσκων τὸν Θεὸν, ἀκούει ἡμῶν, ὃς οὐκ ἔστιν ἐκ τοῦ Θεοῦ, οὐκ ἀκούει ἡμῶν. Ἐκ τούτου γινώσκομεν τὸ πνεῦμα τῆς ἀληθείας καὶ τὸ πνεῦμα τῆς πλάνης.
Ἀγαπητοί, ἀγαπῶμεν ἀλλήλους, ὅτι ἡ ἀγάπη ἐκ τοῦ Θεοῦ ἐστιν, καὶ πᾶς ὁ ἀγαπῶν, ἐκ τοῦ Θεοῦ γεγέννηται, καὶ γινώσκει τὸν Θεόν.
Ὁ μὴ ἀγαπῶν, οὐκ ἔγνω τὸν Θεόν, ὅτι ὁ Θεὸς ἀγάπη ἐστίν.
Ἐν τούτῳ ἐφανερώθη ἡ ἀγάπη τοῦ Θεοῦ ἐν ἡμῖν, ὅτι τὸν Υἱὸν αὐτοῦ, τὸν μονογενῆ, ἀπέσταλκεν ὁ Θεὸς εἰς τὸν κόσμον, ἵνα ζήσωμεν διʼ αὐτοῦ.
Ἐν τούτῳ ἐστὶν ἡ ἀγάπη, οὐχ ὅτι ἡμεῖς ἠγαπήκαμεν τὸν Θεόν, ἀλλʼ ὅτι αὐτὸς ἠγάπησεν ἡμᾶς, καὶ ἀπέστειλεν τὸν Υἱὸν αὐτοῦ, ἱλασμὸν περὶ τῶν ἁμαρτιῶν ἡμῶν.
Ἀγαπητοί, εἰ οὕτως ὁ Θεὸς ἠγάπησεν ἡμᾶς, καὶ ἡμεῖς ὀφείλομεν ἀλλήλους ἀγαπᾶν.
Θεὸν οὐδεὶς πώποτε τεθέαται, ἐὰν ἀγαπῶμεν ἀλλήλους, ὁ Θεὸς ἐν ἡμῖν μένει, καὶ ἡ ἀγάπη αὐτοῦ τετελειωμένη ἐν ἡμῖν ἐστίν.
Ἐν τούτῳ γινώσκομεν, ὅτι ἐν αὐτῷ μένομεν, καὶ αὐτὸς ἐν ἡμῖν, ὅτι ἐκ τοῦ Πνεύματος αὐτοῦ δέδωκεν ἡμῖν.
Καὶ ἡμεῖς τεθεάμεθα καὶ μαρτυροῦμεν ὅτι ὁ Πατὴρ ἀπέσταλκεν τὸν Υἱὸν, Σωτῆρα τοῦ κόσμου.
Ὃς ἂν ὁμολογήσῃ ὅτι Ἰησοῦς ἐστιν ὁ Υἱὸς τοῦ Θεοῦ, ὁ Θεὸς ἐν αὐτῷ μένει, καὶ αὐτὸς ἐν τῷ Θεῷ.
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.
Ἐν τούτῳ τετελείωται ἡ ἀγάπη μεθʼ ἡμῶν, ἵνα παρρησίαν ἔχωμεν ἐν τῇ ἡμέρᾳ τῆς κρίσεως, ὅτι καθὼς ἐκεῖνός ἐστιν, καὶ ἡμεῖς ἐσμεν ἐν τῷ κόσμῳ τούτῳ.
Φόβος οὐκ ἔστιν ἐν τῇ ἀγάπῃ, ἀλλʼ ἡ τελεία ἀγάπη ἔξω βάλλει τὸν φόβον, ὅτι ὁ φόβος κόλασιν ἔχει, ὁ δὲ φοβούμενος, οὐ τετελείωται ἐν τῇ ἀγάπῃ.
Ἡμεῖς ἀγαπῶμεν, ὅτι αὐτὸς πρῶτος ἠγάπησεν ἡμᾶς.
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, οὐ δύναται ἀγαπᾶν.
Καὶ ταύτην τὴν ἐντολὴν ἔχομεν ἀπʼ αὐτοῦ, ἵνα ὁ ἀγαπῶν τὸν Θεὸν, ἀγαπᾷ καὶ τὸν ἀδελφὸν αὐτοῦ.
