The Douay-Rheims Bible in Bishop Challoner's revision (1749-52), the standard English Bible of the Catholic Church for two centuries, translated from the Latin Vulgate, with the Clementine Vulgate Latin beside each verse. The English is that of Project Gutenberg's electronic text, with Challoner's notes left out; the Latin is the Clementine Vulgate of 1598, with the medieval Glossa Ordinaria commentary of the edition left out. Book names and chapter and verse numbers follow the Vulgate, so the Psalms are numbered as in the Vulgate (Psalm 22 here is Psalm 23 in the King James Version).
1That 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 nostræ contrectaverunt de verbo vitæ:
2For 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 æternam, quæ erat apud Patrem, et apparuit nobis:
3That 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.
4And these things we write to you, that you may rejoice and your joy may be full.
Et hæc scribimus vobis ut gaudeatis, et gaudium vestrum sit plenum.
5And 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 hæc est annuntiatio, quam audivimus ab eo, et annuntiamus vobis: quoniam Deus lux est, et tenebræ in eo non sunt ullæ.
6If 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.
7But 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.
8If 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.
9If 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.
10If 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.
