The Journal of Negro History, Volume 5, 1920

In the early history of America there were three types of settlements—the French, Spanish, and English. In the French Provinces the teachings of the "Code Noir" made it incumbent upon the masters to teach the slaves, at least to read, in order, of course, that they might read the Bible; and in the Spanish districts the Latin custom of miscegenation prevented the rise of objections to the teaching of slaves, in case there should be any who cared to instruct the Negroes. In the English Provinces, on the other hand, since teaching the slaves would probably result in their becoming Christians, the colonists[Pg 2] naturally were strenuous in their efforts to prevent any enlightenment of the blacks, due to the existence of an unwritten law to the effect that no Christian might be held a slave. Many planters forbade the teaching of their slaves, until finally the Bishop of London settled the difficulty by issuing a formal declaration in which he stated that conversion did not work manumission.[2]
