Who was Martin Luther? What is the Reformation and why does it matter? Roughly 500 years ago, Luther is said to have nailed his 95 Theses on the door of the Castle Church in Germany. With the help of the printing press, this 16th century protest against corruption in the Catholic Church would drastically change the course of Christianity - and history itself.
