The Council of Trent met from 1545 to 1563 to address disputes with Protestants by condemning Protestant doctrines and defining Catholic church doctrine. It declared the Church's interpretation of the Bible as final and heretical to substitute one's own interpretation. It also defined salvation as coming through both faith and works. The Council issued decrees reforming church practices like indulgences and established the Jesuits order led by Ignatius of Loyola to spread Catholic teachings through education and missions to counter the spread of Protestantism.
