So it was done in ancient Rome. There boys were so taught that by the time they reached their fifteenth, eighteenth, or twentieth year they were well versed in Latin, Greek, and all the liberal arts (as they are called), and then immediately entered upon a political or military career. Their system produced intelligent, wise, and competent men, so skilled in every art and rich in experience that if all the bishops, priests, and monks in the whole of Germany today were rolled into one, you would not have the equal of a single Roman soldier. As a result their country prospered; they had capable and trained men for every position. So at all times throughout the world simple necessity has forced men, even among the heathen, to maintain pedagogues and schoolmasters if their nation was to be brought to a high standard. Hence, the word “schoolmaster” is used by Paul in Galatians 4 as a word taken from the common usage and practice of mankind, where he says, “The law was our schoolmaster.” (Luther’s Works, v. 45 p. 356).
