Robert Charles Sproul, is an American Calvinist theologian, philosopher, author, and pastor. He is the founder and chairman of Ligonier Ministries and can be heard daily on the Renewing Your Mind radio broadcast in the United States and internationally. "Renewing Your Mind with Dr. R.C. Sproul" is also broadcast on Sirius and XM satellite radio. In late July, 2012, a new 24-hour online radio station coined RefNet was also announced by Ligonier Ministries in an effort to reach "as many people as possible" where internet access is available.
Ligonier Ministries hosts several theological conferences each year, including the main conference held each year in Orlando, Florida, at which Sproul is one of the primary speakers.
Sproul was passenger on the train wreck at Big Bayou Canot in 1993 and often gives firsthand accounts of the story.
For (Martin) Luther, the sola of "Sola Scriptura" was inseparably related to the Scriptures' unique inerrancy. It was because popes could and did err and because councils could and did err that Luther came to realize the supremacy of Scripture. Luther did not despise church authority, nor did he repudiate church councils as having no value. His praise of the Council of Nicaea is noteworthy. Luther and the Reformers did not mean by "Sola Scriptura" that the Bible is the only authority in the church; rather, they meant that the Bible is the only infallible authority in the church.
