Five hundred years ago, a Catholic monk nailed a list of grievances on the door of a church in Germany and launched a revolution in the history of Christianity. Today there continues to be a number of unresolved issues between the Protestant and Catholic churches, and many experience this ongoing division within their family and among friends and neighbors.

Written in an accessible and informative style, Gregg Allison and Chris Castaldo provide a brief and clear guide to the key points of unity and divergence between Protestants and Catholics today. They write to encourage fruitful conversation about the key theological and sociological differences between the two largest branches of the Christian Church.

From the revolutionary events 500 years ago that sparked the Reformation to today, Unfinished Reformation takes a nuanced and thoughtful look at doctrine, practice, and how Protestants and Catholics can have fruitful discussions about the gospel of Jesus Christ.
