In 1836 William and Alexander McGuffey began publishing their “Eclectic Series” of textbooks, better know as McGuffey’s Readers. The books sold more than 120 million copies worldwide and have recently become popular again with home schoolers. The McGuffeys were devout Christians, and the Readers taught morals as well as language. Lessons in the Readers included “The Bible the Best of Classics,” “Respect for the Sabbath Rewarded,” and many other Bible-based moral lessons.
