There were many councils, papal bulls, and encyclicals on the spread of heresy up to the council of trent in 1551. This was the definetive eccumenical council addressing the most wide spread errors of the protestant revolution. The jesuits were also formed shortly before this and they were called on by the pope to help combat the errors of protestantism at this time by evangelizing, debating, and generating theological works against the emerging heretics or teachers of anti-Catholic doctrine.
The most important difference between Catholicism and Protestantism, although there are many, is the fact that Protestantism does not believe that the Eucharist is the Body, Blood, Soul and Divinity of Jesus Christ, but believes it is only a remembrance.
