ΙΩΑΝΝΟΥ Α΄.
4.
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 ἐστέ, 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 δι’ αὐτοῦ. 
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. 
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 ἐστιν. 
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 μεθ’ 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, ἀλλ’ 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 ἀπ’ αὐτοῦ, ἵνα ὁ ἀγαπῶν τὸν θεὸν ἀγαπᾷ καὶ τὸν ἀδελφὸν αὐτοῦ.
