1Jn 1 (King James)

   ¹ That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; ² (For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;) ³ That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. ⁴ And these things write we unto you, that your joy may be full.
   ⁵ This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. ⁶ If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: ⁷ But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
   ⁸ If we say that we have no sin, we deceive ourselves, and the truth is not in us. ⁹ If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. ¹⁰ If we say that we have not sinned, we make him a liar, and his word is not in us.

1Jn 1 (Stephanus 1550)

   ¹ ὅ ἦν ἀπ᾽ ἀρχῆς, ὃ ἀκηκόαμεν, ὃ ἑωράκαμεν τοῖς ὀφθαλμοῖς ἡμῶν, ὃ ἐθεασάμεθα, καὶ αἱ χεῖρες ἡμῶν ἐψηλάφησαν περὶ τοῦ λόγου τῆς ζωῆς, ² καὶ ἡ ζωὴ ἐφανερώθη καὶ ἑωράκαμεν, καὶ μαρτυροῦμεν, καὶ ἀπαγγέλλομεν ὑμῖν τὴν ζωὴν τὴν αἰώνιον, ἥτις ἦν πρὸς τὸν πατέρα, καὶ ἐφανερώθη ἡμῖν ³ ὃ ἑωράκαμεν καὶ ἀκηκόαμεν, ἀπαγγέλλομεν ὑμῖν, ἵνα καὶ ὑμεῖς κοινωνίαν ἔχητε μεθ᾽ ἡμῶν, καὶ ἡ κοινωνία δὲ ἡ ἡμετέρα μετὰ τοῦ πατρὸς καὶ μετὰ τοῦ υἱοῦ αὐτοῦ ἰησοῦ χριστοῦ ⁴ καὶ ταῦτα γράφομεν ὑμῖν, ἵνα ἡ χαρὰ ἡμῶν ᾖ πεπληρωμένη ⁵ καὶ αὕτη ἐστὶν ἡ ἐπαγγελία ἣν ἀκηκόαμεν ἀπ᾽ αὐτοῦ, καὶ ἀναγγέλλομεν ὑμῖν, ὅτι ὁ θεὸς φῶς ἐστιν, καὶ σκοτία ἐν αὐτῷ οὐκ ἔστιν οὐδεμία ⁶ ἐὰν εἴπωμεν ὅτι κοινωνίαν ἔχομεν μετ᾽ αὐτοῦ, καὶ ἐν τῷ σκότει περιπατῶμεν, ψευδόμεθα, καὶ οὐ ποιοῦμεν τὴν ἀλήθειαν ⁷ ἐὰν δὲ ἐν τῷ φωτὶ περιπατῶμεν, ὡς αὐτός ἐστιν ἐν τῷ φωτὶ, κοινωνίαν ἔχομεν μετ᾽ ἀλλήλων, καὶ τὸ αἷμα ἰησοῦ χριστοῦ τοῦ υἱοῦ αὐτοῦ καθαρίζει ἡμᾶς ἀπὸ πάσης ἁμαρτίας ⁸ ἐὰν εἴπωμεν ὅτι ἁμαρτίαν οὐκ ἔχομεν, ἑαυτοὺς πλανῶμεν, καὶ ἡ ἀλήθεια οὐκ ἔστιν ἐν ἡμῖν ⁹ ἐὰν ὁμολογῶμεν τὰς ἁμαρτίας ἡμῶν, πιστός ἐστιν καὶ δίκαιος ἵνα ἀφῇ ἡμῖν τὰς ἁμαρτίας, καὶ καθαρίσῃ ἡμᾶς ἀπὸ πάσης ἀδικίας ¹⁰ ἐὰν εἴπωμεν ὅτι οὐχ ἡμαρτήκαμεν, ψεύστην ποιοῦμεν αὐτὸν, καὶ ὁ λόγος αὐτοῦ οὐκ ἔστιν ἐν ἡμῖν
