The Louvain Vulgate played an important role in the development of the Catholic Bible used today. In 1546, partly in response to the Protestant Reformation, the Council of Trent declared the Latin Vulgate to be the authentic version of the Bible. At the time, however, there were textual variations between different editions of the Vulgate, and no edition was accepted as standard. In response, John Henten, a biblical scholar in Louvain, sought to produce a more reliable edition by comparing over 30 Latin manuscripts and drawing from the work of earlier scholars such as Robert Estienne. His Louvain Vulgate, published in 1547, essentially served as the standard text of the Catholic Church until the Sixtine Vulgate was published in 1590.
