The idea of the singular authority of scripture is the motivation behind much of the Protestant effort to translate the Bible into vernacular languages and distribute it widely. Protestants generally believe each Christian should read the Bible for themselves and evaluate what they have been taught on the basis of it. In the Roman Catholic and Eastern Orthodox Church, both of which teach that authoritative doctrine can also come from tradition, have been more active in translating them as well as the Bible into the vernacular languages. Contrary to a common polemic of the Reformation, many German translations of the bible existed before Martin Luther. Traditions of these non-Protestant churches include the Bible, patristic, conciliar, and liturgical texts. Prior to the Protestant movement, hundreds of vernacular translations of the Bible and liturgical materials were translated throughout the preceding sixteen centuries. Some Bible translations such as the Geneva Bible included annotations and commentary that were anti-Roman Catholic. Before the Protestant Reformation, Latin was almost exclusively utilized in Latin Rite Catholic Churches, but was understood by only the most literate.
