One Saint, whom I'd never heard of, has quite a legacy! He stayed IN the Church, unlike Martin Luther, to provide needed reform. Check out St. Cajetan, who's feast day was yesterday. And another fine article on this Saint.

an excerpt: "Divine Providence always calls someone to counter-attack the evil that is afflicting the Church and Christendom. Today the great scourge chastising the Church and Christendom is the Revolution. The Revolution in the Church is called Progressivism; in the temporal sphere it is called Communism, Self-managing Socialism and Tribalism. Therefore, there should be some Catholics who are specially called to take the Counter-Revolution to its furthest limits. We are called to be these Catholics. "
