Early in the course of the Reformation (1520) Martin Luther penned a trilogy of foundational documents addressing the German Nobility, the Church and the Christian. "To the Christian Nobility" appeared first. In it, Luther identifies and attacks the three walls with which the papacy insulates itself from reformation. Next, he discusses three areas that need to be addressed by a council. Finally, he offers 27 articles respecting reforms needed in Christendom. (Summary by Jonathan Lange)
