reject it under any pretext whatever.The qualifier "Latin editions, now in circulation" and the use of "authentic" (not "inerrant") show the limits of this statement. When the council listed the books included in the canon, it qualified the books as being "entire with all their parts, as they have been used to be read in the Catholic Church, and as they are contained in the Vetus Latina vulgate edition". The fourth session of the Council specified 72 canonical books in the Bible: 45 in the Old Testament, 27 in the New Testament with Lamentations not being counted as separate from Jeremiah. On 2 June 1927, Pope Pius XI clarified this decree, allowing that the Comma Johanneum was open to dispute. Later, in the 20th century, Pope Pius XII declared the Vulgate as "free from error whatsoever in matters of faith and morals" in his encyclical Divino Afflante Spiritu: The inerrancy is with respect to faith and morals, as it says in the above quote: "free from any error whatsoever in matters of faith and morals", and the inerrancy is not in a philological sense: The Catholic Church has produced three official editions of the Vulgate: the Sixtine Vulgate, the Clementine Vulgate, and the Nova Vulgata (see below).

Indeed, for most medieval Western Christians, it was the only version of the Bible ever encountered. In about 1455, the first Vulgate published by the moveable type process was produced in Mainz by a partnership between Johannes Gutenberg and banker John Fust (or Faust). At the time, a manuscript of the Vulgate was selling for approximately 500 guilders. Gutenberg's works appear to have been a commercial failure, and Fust sued for recovery of his 2026 guilder investment and was awarded complete possession of the Gutenberg plant. Arguably, the Reformation could not have been possible without the diaspora of biblical knowledge that was permitted by the development of moveable type. Aside from its use in prayer, liturgy, and private study, the Vulgate served as inspiration for ecclesiastical art and architecture, hymns, countless paintings, and popular mystery plays. Reformation The fifth volume of Walton's London Polyglot of 1657 included several versions of the New Testament: in Greek, Latin (a Vulgate version and the version by Arius
