What has changed since the 16th Century Protestant Reformation?
Dr. R. C. Sproul:
In Dr. Sproul's latest book "Are We Together?: A Protestant Analyzes Roman Catholicism" he discusses six core doctrines in which Roman Catholicism is at odds with the clear teaching of the Bible; namely Scripture, justification, the Church, sacraments, the papacy and the role of Mary. He also describes how Protestants should relate to Roman Catholics without minimizing the vital differences. The book is available at a 25% discount from monergismbooks.com at this link.
