"John Locke stated that in his opinion the best way for an adult to learn Latin was by reading the Latin Bible, and so great a linguistic genius as Lord Macaulay did not disdain to learn German from the German Bible. The author feels confident from experience that those who begin with the Latin Bible and the easy Ecclesiastical authors will be able to go to the study of the Classics, if they desire to do so, with far more intelligence and profit than if they had tried to approach them without some previous preparation."
