᾿Αγαπητοί, ἀγαπῶμεν ἀλλήλους, ὅτι ἡ ἀγάπη ἐκ τοῦ Θεοῦ ἐστι, 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 ἀπέστειλε τὸν υἱὸν αὐτοῦ ἱλασμὸν περὶ τῶν ἁμαρτιῶν ἡμῶν. ᾿Αγαπητοί, 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 ἐστὶν ἐν ἡμῖν. 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 ἀπέσταλκε τὸν υἱὸν σωτῆρα τοῦ κόσμου. ὃς ἂν ὁμολογήσῃ ὅτι ᾿Ιησοῦς 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. ῾Ο Θεὸς ἀγάπη ἐστί, καὶ ὁ μένων ἐν τῇ ἀγάπῃ ἐν τῷ Θεῷ μένει καὶ ὁ Θεὸς ἐν αὐτῷ. ᾿Εν τούτῳ τετελείωται ἡ ἀγάπη μεθ᾿ ἡμῶν, ἵνα παρρησίαν ἔχωμεν ἐν τῇ ἡμέρᾳ τῆς κρίσεως, ὅτι καθὼς ἐκεῖνός ἐστι, 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. ῾Ημεῖς ἀγαπῶμεν αὐτόν, 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 ὃν ἐώρακε, τὸν Θεόν ὃν οὐχ ἑώρακε πῶς δύναται ἀγαπᾶν; καὶ ταύτην τὴν ἐντολὴν ἔχομεν ἀπ᾿ αὐτοῦ, ἵνα ὁ ἀγαπῶν τὸν Θεὸν ἀγαπᾷ καὶ τὸν ἀδελφὸν αὐτοῦ.
