1Jn 5 (King James)

¹ Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
² By this we know that we love the children of God, when we love God, and keep his commandments.
³ For this is the love of God, that we keep his commandments: and his commandments are not grievous.
⁴ For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
⁵ Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
⁶ This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that beareth witness, because the Spirit is truth.
⁷ For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
⁸ And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.
⁹ If we receive the witness of men, the witness of God is greater: for this is the witness of God which he hath testified of his Son.
¹⁰ He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
¹¹ And this is the record, that God hath given to us eternal life, and this life is in his Son.
¹² He that hath the Son hath life; and he that hath not the Son of God hath not life.
¹³ These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
¹⁴ And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
¹⁵ And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
¹⁶ If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.
¹⁷ All unrighteousness is sin: and there is a sin not unto death.
¹⁸ We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
¹⁹ And we know that we are of God, and the whole world lieth in wickedness.
²⁰ And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
²¹ Little children, keep yourselves from idols. Amen.

1Jn 5 (Stephanus 1550)

¹ πᾶς ὁ πιστεύων ὅτι ἰησοῦς ἐστιν ὁ χριστὸς, ἐκ τοῦ θεοῦ γεγέννηται καὶ πᾶς ὁ ἀγαπῶν τὸν γεννήσαντα, ἀγαπᾷ καὶ τὸν γεγεννημένον ἐξ αὐτοῦ
² ἐν τούτῳ γινώσκομεν ὅτι ἀγαπῶμεν τὰ τέκνα τοῦ θεοῦ, ὅταν τὸν θεὸν ἀγαπῶμεν, καὶ τὰς ἐντολὰς αὐτοῦ τηρῶμεν
³ αὕτη γάρ ἐστιν ἡ ἀγάπη τοῦ θεοῦ, ἵνα τὰς ἐντολὰς αὐτοῦ τηρῶμεν καὶ αἱ ἐντολαὶ αὐτοῦ βαρεῖαι οὐκ εἰσὶν,
⁴ ὅτι πᾶν τὸ γεγεννημένον ἐκ τοῦ θεοῦ νικᾷ τὸν κόσμον καὶ αὕτη ἐστὶν ἡ νίκη ἡ νικήσασα τὸν κόσμον, ἡ πίστις ἡμῶν
⁵ τίς ἐστιν ὁ νικῶν τὸν κόσμον, εἰ μὴ ὁ πιστεύων ὅτι ἰησοῦς ἐστιν ὁ υἱὸς τοῦ θεοῦ
⁶ οὗτός ἐστιν ὁ ἐλθὼν δι᾽ ὕδατος καὶ αἵματος, ἰησοῦς ὁ χριστός οὐκ ἐν τῷ ὕδατι μόνον, ἀλλ᾽ ἐν τῷ ὕδατι καὶ τῷ αἵματι καὶ τὸ πνεῦμά ἐστιν τὸ μαρτυροῦν, ὅτι τὸ πνεῦμά ἐστιν ἡ ἀλήθεια
⁷ ὅτι τρεῖς εἰσιν οἱ μαρτυροῦντες ἐν τῷ οὐρανῷ, ὁ πατὴρ, ὁ λόγος, καὶ τὸ ἅγιον πνεῦμα καὶ οὗτοι οἱ τρεῖς ἕν εἰσιν
⁸ καὶ τρεῖς εἰσιν οἱ μαρτυροῦντες ἐν τῇ γῇ, τὸ πνεῦμα, καὶ τὸ ὕδωρ, καὶ τὸ αἷμα καὶ οἱ τρεῖς εἰς τὸ ἕν εἰσιν
⁹ εἰ τὴν μαρτυρίαν τῶν ἀνθρώπων λαμβάνομεν, ἡ μαρτυρία τοῦ θεοῦ μείζων ἐστὶν, ὅτι αὕτη ἐστὶν ἡ μαρτυρία τοῦ θεοῦ ἣν μεμαρτύρηκεν περὶ τοῦ υἱοῦ αὑτοῦ
¹⁰ ὁ πιστεύων εἰς τὸν υἱὸν τοῦ θεοῦ, ἔχει τὴν μαρτυρίαν ἐν ἑαυτῷ ὁ μὴ πιστεύων τῷ θεῷ, ψεύστην πεποίηκεν αὐτὸν, ὅτι οὐ πεπίστευκεν εἰς τὴν μαρτυρίαν ἣν μεμαρτύρηκεν ὁ θεὸς περὶ τοῦ υἱοῦ αὑτοῦ
¹¹ καὶ αὕτη ἐστὶν ἡ μαρτυρία, ὅτι ζωὴν αἰώνιον ἔδωκεν ἡμῖν ὁ θεὸς, καὶ αὕτη ἡ ζωὴ ἐν τῷ υἱῷ αὐτοῦ ἐστιν
¹² ὁ ἔχων τὸν υἱὸν, ἔχει τὴν ζωήν ὁ μὴ ἔχων τὸν υἱὸν τοῦ θεοῦ, τὴν ζωὴν οὐκ ἔχει
¹³ ταῦτα ἔγραψα ὑμῖν τοῖς πιστεύουσιν εἰς τὸ ὄνομα τοῦ υἱοῦ τοῦ θεοῦ, ἵνα εἰδῆτε ὅτι ζωὴν ἔχετε αἰώνιον, καὶ ἵνα πιστεύητε εἰς τὸ ὄνομα τοῦ ὑιοῦ τοῦ θεοῦ
¹⁴ καὶ αὕτη ἐστὶν ἡ παῤῥησία ἣν ἔχομεν πρὸς αὐτὸν, ὅτι ἐάν τι αἰτώμεθα κατὰ τὸ θέλημα αὐτοῦ, ἀκούει ἡμῶν
¹⁵ καὶ ἐὰν οἴδαμεν ὅτι ἀκούει ἡμῶν ὃ ἂν αἰτώμεθα, οἴδαμεν ὅτι ἔχομεν τὰ αἰτήματα ἃ ᾐτήκαμεν παρ᾽ αὐτοῦ
¹⁶ ἐάν τις ἴδῃ τὸν ἀδελφὸν αὑτοῦ ἁμαρτάνοντα ἁμαρτίαν μὴ πρὸς θάνατον, αἰτήσει, καὶ δώσει αὐτῷ ζωὴν, τοῖς ἁμαρτάνουσιν μὴ πρὸς θάνατον ἔστιν ἁμαρτία πρὸς θάνατον, οὐ περὶ ἐκείνης λέγω ἵνα ἐρωτήσῃ
¹⁷ πᾶσα ἀδικία ἁμαρτία ἐστὶν, καὶ ἔστιν ἁμαρτία οὐ πρὸς θάνατον
¹⁸ οἴδαμεν ὅτι πᾶς ὁ γεγεννημένος ἐκ τοῦ θεοῦ οὐχ ἁμαρτάνει ἀλλ᾽ ὁ γεννηθεὶς ἐκ τοῦ θεοῦ τηρεῖ ἐαυτὸν, καὶ ὁ πονηρὸς οὐχ ἅπτεται αὐτοῦ
¹⁹ οἴδαμεν ὅτι ἐκ τοῦ θεοῦ ἐσμὲν, καὶ ὁ κόσμος ὅλος ἐν τῷ πονηρῷ κεῖται
²⁰ οἴδαμεν δὲ ὅτι ὁ υἱὸς τοῦ θεοῦ ἥκει, καὶ δέδωκεν ἡμῖν διάνοιαν ἵνα γινώσκωμεν τὸν ἀληθινόν καί ἐσμεν ἐν τῷ ἀληθινῷ, ἐν τῷ υἱῷ αὐτοῦ ἰησοῦ χριστῷ οὗτός ἐστιν ὁ ἀληθινὸς θεὸς, καὶ ἡ ζωὴ αἰώνιος
²¹ τεκνία, φυλάξατε ἑαυτοὺς ἀπὸ τῶν εἰδώλων ἀμήν

1Jn 5 (Vulgate)

¹ Omnis qui credit quoniam Jesus est Christus, ex Deo natus est. Et omnis qui diligit eum qui genuit, diligit et eum qui natus est ex eo.
² In hoc cognoscimus quoniam diligimus natos Dei, cum Deum diligamus, et mandata ejus faciamus.
³ Hæc est enim caritas Dei, ut mandata ejus custodiamus : et mandata ejus gravia non sunt.
⁴ Quoniam omne quod natum est ex Deo, vincit mundum : et hæc est victoria, quæ vincit mundum, fides nostra.
⁵ Quis est, qui vincit mundum, nisi qui credit quoniam Jesus est Filius Dei ?
⁶ Hic est, qui venit per aquam et sanguinem, Jesus Christus : non in aqua solum, sed in aqua et sanguine. Et Spiritus est, qui testificatur quoniam Christus est veritas.
⁷ Quoniam tres sunt, qui testimonium dant in cælo : Pater, Verbum, et Spiritus Sanctus : et hi tres unum sunt.
⁸ Et tres sunt, qui testimonium dant in terra : spiritus, et aqua, et sanguis : et hi tres unum sunt.
⁹ Si testimonium hominum accipimus, testimonium Dei majus est : quoniam hoc est testimonium Dei, quod majus est, quoniam testificatus est de Filio suo.
¹⁰ Qui credit in Filium Dei, habet testimonium Dei in se. Qui non credit Filio, mendacem facit eum : quia non credit in testimonium quod testificatus est Deus de Filio suo.
¹¹ Et hoc est testimonium, quoniam vitam æternam dedit nobis Deus : et hæc vita in Filio ejus est.
¹² Qui habet Filium, habet vitam : qui non habet Filium, vitam non habet.
¹³ Hæc scribo vobis ut sciatis quoniam vitam habetis æternam, qui creditis in nomine Filii Dei.
¹⁴ Et hæc est fiducia, quam habemus ad eum : quia quodcumque petierimus, secundum voluntatem ejus, audit nos.
¹⁵ Et scimus quia audit nos quidquid petierimus : scimus quoniam habemus petitiones quas postulamus ab eo.
¹⁶ Qui scit fratrem suum peccare peccatum non ad mortem, petat, et dabitur ei vita peccanti non ad mortem. Est peccatum ad mortem : non pro illo dico ut roget quis.
¹⁷ Omnis iniquitas, peccatum est : et est peccatum ad mortem.
¹⁸ Scimus quia omnis qui natus est ex Deo, non peccat : sed generatio Dei conservat eum, et malignus non tangit eum.
¹⁹ Scimus quoniam ex Deo sumus : et mundus totus in maligno positus est.
²⁰ Et scimus quoniam Filius Dei venit, et dedit nobis sensum ut cognoscamus verum Deum, et simus in vero Filio ejus. Hic est verus Deus, et vita æterna.
²¹ Filioli, custodite vos a simulacris. Amen.
