He declares what he has seen and heard of Christ who is the life eternal, to the end that we may have fellowship with God and all good through him. Yet so if we confess our sins.

 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:
Quod fuit ab initio, quod audivimus, quod vidimus oculis nostris, quod perspeximus, et manus nostrae contrectaverunt de verbo vitae :

 2 For the life was manifested; and we have seen and do bear witness, and declare unto you the life eternal, which was with the Father, and hath appeared to us:
et vita manifestata est, et vidimus, et testamur, et annuntiamus vobis vitam aeternam, quae erat apud Patrem, et apparuit nobis :

 3 That which we have seen and have heard, we declare unto you, that you also may have fellowship with us, and our fellowship may be with the Father, and with his Son Jesus Christ.
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 And these things we write to you, that you may rejoice, and your joy may be full.
Et haec scribimus vobis ut gaudeatis, et gaudium vestrum sit plenum.

 5 And this is the declaration which we have heard from him, and declare unto you: That God is light, and in him there is no darkness.
Et haec est annuntiatio, quam audivimus ab eo, et annuntiamus vobis : quoniam Deus lux est, et tenebrae in eo non sunt ullae.

 6 If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth.
Si dixerimus quoniam societatem habemus cum eo, et in tenebris ambulamus, mentimur, et veritatem non facimus.

 7 But if we walk in the light, as he also is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
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 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Si dixerimus quoniam peccatum non habemus, ipsi nos seducimus, et veritas in nobis non est.

 9 If we confess our sins, he is faithful and just, to forgive us our sins, and to cleanse us from all iniquity.
Si confiteamur peccata nostra : fidelis est, et justus, ut remittat nobis peccata nostra, et emundet nos ab omni iniquitate.

 10 If we say that we have not sinned, we make him a liar, and his word is not in us.
Si dixerimus quoniam non peccavimus, mendacem facimus eum, et verbum ejus non est in nobis.
