1 That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked at and our hands have touched —this we proclaim concerning the Word of life.2 The life appeared; we have seen it and testify to it, and we proclaim to you the eternal life, which was with the Father and has appeared to us.3 We proclaim to you what we have seen and heard, so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ.4 We write this to make our "joy complete.5 This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all.6 If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth.7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all "sin.8 If we claim to be without sin, we deceive ourselves and the truth is not in us.9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.

1 Quod fuit ab initio, quod audivimus, quod vidimus oculis nostris, quod perspeximus, et manus nostr contrectaverunt de verbo vit : 2 et vita manifestata est, et vidimus, et testamur, et annuntiamus vobis vitam ternam, qu erat apud Patrem, et apparuit nobis : 3 quod vidimus et audivimus, annuntiamus vobis, ut et vos societatem habeatis nobiscum, et societas nostra sit cum Patre, et cum Filio ejus Jesu Christo. 4 Et hc scribimus vobis ut gaudeatis, et gaudium vestrum sit plenum.5 Et hc est annuntiatio, quam audivimus ab eo, et annuntiamus vobis : quoniam Deus lux est, et tenebr in eo non sunt ull. 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.
