He published the Roman Catechism, the revised Roman Breviary, and the Roman Missal; he also declared Thomas Aquinas a Doctor of the Church, commanded a new edition of the works of Thomas Aquinas, and created a commission to revise the Vulgate. The decrees of Trent were published throughout all Catholic lands, including Europe, Asia, Africa, and the New World, and the pontiff insisted on their strict adherence. In 1571, Pius created the Congregation of the Index to give strength to the Church's resistance to Protestant and heretical writings, and he used the Inquisition to prevent any Protestant ideas from gaining a foot hold in Italy. In dealing with the threat of the Ottoman Turks who were advancing steadily across the Mediterranean, Pius organized a formidable alliance between Venice and Spain, culminating in the Battle of Lepanto, which was a complete and shattering triumph over the Turks. The day of the victory was declared the Feast Day of Our Lady of Victory in recognition of Our Lady's intercession in answer to the saying of the Rosary all over Catholic Europe. Pius also spurred the reforms of the Church by example. He insisted upon wearing his coarse Dominican robes, even beneath the magnificent vestments worn by the popes, and was wholeheartedly devoted to the religious life. His reign was blemished only by the continuing oppression of the Inquisition; the often brutal treatment of the Jews of Rome; and the ill-advised decision to excommunicate Queen Elizabeth I of England in February 1570, an act which also declared her deposed and which only worsened the plight of English Catholics. These were overshadowed in the view of later generations by his contributions to the Catholic Reformation. Pope Clement beatified him on May 1, 1672, and Pope Clement XI canonized him on May
