When the Protestant Reformation broke out in Western Europe, the Catholic Church got the message, at least a little bit. Pope Paul III called a council to look into reforming some aspects of the Catholic Church and try to stem the tide of competing Christian sects popping up all over the place. The Council of Trent changed some aspects of the organization, but doubled down on a lot of the practices that Martin Luther and other reformers had a problem with. Today you'll learn about the Council of Trent, the rise of the Jesuits, and Saint Teresa of Avila.
