1Jn 1:5-2:2 (King James)

   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.

1 Jean 2

   ¹ My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous: ² And he is the propitiation for our sins: and not for our's only, but also for the sins of the whole world.

1Jn 1:5-2:2 (Vulgate)

   ⁵ Et hæc est annuntiatio, quam audivimus ab eo, et annuntiamus vobis : quoniam Deus lux est, et tenebræ in eo non sunt ullæ.
   ⁶ Si dixerimus quoniam societatem habemus cum eo, et in tenebris ambulamus, mentimur, et veritatem non facimus.
   ⁷ Si autem in luce ambulamus sicut et ipse est in luce, societatem habemus ad invicem, et sanguis Jesu Christi, Filii ejus, emundat nos ab omni peccato.
   ⁸ Si dixerimus quoniam peccatum non habemus, ipsi nos seducimus, et veritas in nobis non est.
   ⁹ Si confiteamur peccata nostra : fidelis est, et justus, ut remittat nobis peccata nostra, et emundet nos ab omni iniquitate.
   ¹⁰ Si dixerimus quoniam non peccavimus, mendacem facimus eum, et verbum ejus non est in nobis.

1 Jean 2

   ¹ Filioli mei, hæc scribo vobis, ut non peccetis. Sed et si quis peccaverit, advocatum habemus apud Patrem, Jesum Christum justum :
   ² et ipse est propitiatio pro peccatis nostris : non pro nostris autem tantum, sed etiam pro totius mundi.
