When one monk nailed his challenges to the door of the Catholic Church, he had no idea that it would open a crack leading all the way down to the very foundation of medieval theology. He started out only to reform papal errors, but ended up sparking a wholesale return to the biblical gospel, grace, and the Word of Jesus Christ. 'Protestant', a term first used against the followers of this renegade monk by his opponents, was eventually embraced as a rallying cry for participants in the Reformation. This book by A. Blake White will walk you through the five foundational beliefs of those who fought alongside Martin Luther for the purity of the Christian faith. The need for Christians to uphold these truths is as strong today as it was in the 16th century.
