62 But alas! it is clear from the obvious meaning of the words and from experience, that what is intended by not a few, is the withdrawal of education from every sort of dependence on the divine law. So today we see, strange sight indeed, educators and philosophers who spend their lives in searching for a universal moral code of education, as if there existed no decalogue, no gospel law, no law even of nature stamped by God on the heart of man, promulgated by right reason, and codified in positive revelation by God Himself in the ten commandments. These innovators are wont to refer contemptuously to Christian education as "heteronomous," "passive","obsolete," because founded upon the authority of God and His holy law.
