# 1 John 1

1 John 1 is chapter 1 of 5 in the First Letter of John. Here are all 10 verses in the Catholic Public Domain Version, with the Latin of the Clementine Vulgate beside them.

> 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 John 1 (Catholic Public Domain Version)

1. He who was from the beginning, whom we have heard, whom we have seen with our eyes, upon whom we have gazed, and whom our hands have certainly touched: He is the Word of Life.
2. And that Life has been made manifest. And we have seen, and we testify, and we announce to you: the Eternal Life, who was with the Father, and who appeared to us.
3. He whom we have seen and heard, we announce to you, so that you, too, may have fellowship with us, and so that our fellowship may be with the Father and with his Son Jesus Christ.
4. And this we write to you, so that you may rejoice, and so that your joy may be full.
5. And this is the announcement which we have heard from him, and which we announce to you: that God is light, and in him there is no darkness.
6. If we claim that we have fellowship with him, and yet we walk in darkness, then we are lying and not telling the truth.
7. But if we walk in the light, just as he also is in the light, then we have fellowship with one another, and the blood of Jesus Christ, his Son, cleanses us from all sin.
8. If we claim that we have no sin, then we are deceiving ourselves and the truth is not in us.
9. If we confess our sins, then he is faithful and just, so as to forgive us our sins and to cleanse us from all iniquity.
10. If we claim that we have not sinned, then we make him a liar, and his Word is not in us.

## 1 John 1 in Latin (Clementine Vulgate, 1592)

1. Quod fuit ab initio, quod audivimus, quod vidimus oculis nostris, quod perspeximus, et manus nostræ contrectaverunt de verbo vitæ:
2. et vita manifestata est, et vidimus, et testamur, et annuntiamus vobis vitam æternam, quæ 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 hæc scribimus vobis ut gaudeatis, et gaudium vestrum sit plenum.
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.
