The presence of the Freedmen in America is an anomaly in the world's history. European nations have gradually abolished serfdom, and the master and the slave being of the same race, the line of separation has soon broken down. In America, slavery is abolished, but the master and ex-slave are as far apart as ever. America is a nation of immigrants, mostly from Europe and Africa. The Europeans soon assimilate, and only the tradition of the individual family tells of the particular nation from which it came. But the African immigrants are still, after nearly 300 years' residence in America, separated from the white race by visible marks of color and features, and are thus, at the same time, identified with the land of their fathers. Are not these facts suggestive? Does not the persistent race-identity of these people, linking them still with Africa, suggest a duty they may owe to it; and do not their vigorous intellects and warm religious characteristics indicate that duty to be a high and sacred one? On the other hand, Africa, the land of their fathers, is another anomaly in the world's history. For a thousand years it was unknown to the civilized world; its people are the most degraded upon earth, and it is a shame and reproach to the church that it has done so little to enlighten them,--yea, a double shame when, as is now well known, Mohammedanism is spreading most rapidly over the whole continent. These added facts emphasize the question already asked, Are not these freed Negroes peculiarly fitted and providentially called to carry the gospel to their fatherland? Is there not here a Divine purpose that the church should be quick to see and prompt to carry out? As the Hebrews were taken to Egypt, disciplined by bondage, and made familiar with the arts of the most enlightened nation then on earth, and were thus prepared for their high destiny in developing the plan of salvation, so are not these children of Africa, chastened by their severe bondage, brought into contact with the civilization of America, and fitted by their ardent religious impulses, destined to bear a large share in the work of Africa's evangelization? It is to the development of this thought that I invite attention. Let me first revert to the slow progress of Christianity in Africa, Christianity, soon after the apostolic age, made one of its brightest triumphs in Northern Africa--in Egypt and Abyssinia. But ere long that light went out there and never penetrated the great continent. So far as is now known, darkness has ever hovered over it--ignorance, superstition, degradation, cannibalism, slavery and war, have made and perpetuated that darkness.
