Five hundred years ago, an Augustinian monk named Martin Luther nailed his 95 theses to the door of the Catholic Church in Wittenberg, Germany, marking the beginning of what would become known as the Protestant Reformation.

Join us on the Rediscover: Hour as we welcome Protestant ministers Rick Mattson and Jonna Fantz back to the program to talk about how Catholics and Protestants can continue to strive toward true unity.
