Latin manuscripts of the New Testament are handwritten copies of translations from the Greek originals. Translations of the New Testament are called versions. They are important in textual criticism, because sometimes versions provide evidence (called a witness) to an earlier reading of the Greek, i.e. to the text that may have been lost (or preserved only very poorly) in the subsequent Greek tradition. It is also hypothesised that, in some cases, for example, in the case of the Codex Bezae, early Latin manuscripts may have influenced some early Greek manuscripts. Thus, accidentally or deliberately, some Latin readings may have "crossed back over" into the Greek. One possible example of this is the well known Comma Johanneum.
