Church historians tend to split the 2,000 years of Christian history into three categories: ancient, medieval, and modern. For many Protestants, we tend to celebrate heroes of the ancient church such as the apostles, Augustan, or Athanasius. And we also jump to modern heroes like John Bunyan, Charles Spurgeon, and C. S. Lewis. We often erroneously skip over the Medieval Church, which existed during a dark period of church history. The light of the Gospel thankfully broke through with the Reformation of the 16th Century, but there were still titans during the down period, and one of them was a 13th Century Italian Dominican friar who would be remembered as the preeminent Christian thinker of the Dark Ages: St. Thomas Aquinas.
