This book is the Bible as translated by John Wycliffe. Also commonly known as Wycliffe's Bible, these Bible translations were the chief inspiration and chief cause of the Lollard movement, a pre-Reformation movement that rejected many of the distinctive teachings of the Roman Catholic Church. In the early Middle Ages, most Western Christian people encountered the Bible only in the form of oral versions of scriptures, verses and homilies in Latin (other sources were mystery plays, usually performed in the vernacular, and popular iconography). Though relatively few people could read at this time, Wycliffe's idea was to translate the Bible into the vernacular, saying "it helpeth Christian men to study the Gospel in that tongue in which they know best Christ's sentence".
