Again, this work was important because it was public. It was not done in a corner. It was acted on the open stage of history. As these Brethren laboured among the heathen, they were constantly coming into close contact with Governors, with trading companies, and with Boards of Control. In Greenland they were under Danish rule; in Surinam, under Dutch; in North America, under English; in the West Indies, under English, French, Danish, Dutch, Swedish, Spanish, Portuguese; and thus they were teaching a moral lesson to the whole Western European world. At that time the West Indian Islands were the gathering ground for all the powers on the Atlantic seaboard of Europe. There, and there alone in the world, they all had possessions; and there, in the midst of all these nationalities, the Brethren accomplished their most successful work. And the striking fact is that in each of these islands they gained the approval of the Governor. They were the agents of an international Church; they were free from all political complications; they could never be suspected of treachery; they were law-abiding citizens themselves, and taught their converts to be the same; and thus they enjoyed the esteem and support of every great Power in Europe. And this in turn had another grand result. It prepared the way for Negro Emancipation. We must not, however, give the missionaries too much credit. As Zinzendorf himself was a firm believer in slavery, we need not be surprised to find that the Brethren never came forward as champions of liberty. They never pleaded for emancipation. They never encouraged their converts to expect it. They never talked about the horrors of slavery. They never appealed, like Wilberforce, to Parliament. And yet it was just these modest Brethren who did the most to make emancipation possible. Instead of delivering inflamatory speeches, and stirring up the hot-blooded negroes to rebellion, they taught them rather to be industrious, orderly, and loyal, and thus show that they were fit for liberty. If a slave disobeyed his master they punished him. They acted wisely. If the Brethren had preached emancipation they would simply have made their converts restive; and these converts, by rebelling, would only have cut their own throats. Again and again, in Jamaica and Antigua, the negroes rose in revolt; and again and again the Governors noticed that the Moravian converts took no part in the rebellion.
