Two passages of Scripture, one in the Old Testament and the other in the New, both governing this question, attest the Unity of the Human Family. The first is in that sublime chapter of Genesis, where, amidst the wonders of Creation, it is said: “So God created man in His own image; in the image of God created He him; male and female created He them. And God blessed them; and God said unto them, Be fruitful and multiply, and replenish the earth, and subdue it.”[125] The other passage is from that great sermon of Saint Paul, when, standing in the midst of Mars Hill, he proclaimed to the men of Athens, and through them to all mankind, that God “hath made of _one blood_ all nations of men for to dwell on all the face of the earth.”[126] If, as is sometimes argued, there be ambiguity in the account of the Creation, or if in any way its authority has been impaired by scientific criticism, there is nothing of the kind to detract from the sermon of Saint Paul, which must continue forevermore venerable and beautiful. * * * * * Appealing from these texts, the apologists hurry to Science; and there I follow. But I must compress into paragraphs what might fill volumes. Ethnology, to which we repair, is a science of recent origin, exhibiting the different races or varieties of Man in their relations with each other, as that other science, Anthropology, exhibits Man in his relation to the animal world. Nature and History are our authorities, but all science and all knowledge are tributary. Perhaps no other theme is grander; for it is the very beginning of human history, in which all nations and men have a common interest. Its vastness is increased, when we consider that it embraces properly not only the origin, distribution, and capacity of Man, but his destiny on earth,--stretching into the infinite past, stretching also into the infinite future, and thus spanning Humanity. The subject is entirely modern. Hippocrates, one of our ancient masters, has left a treatise on “Air, Water, and Place,” where climatic influences are recognized; but nobody in Antiquity studied the varieties of our race, or regarded its origin except mythically. The discovery of America, and the later circumnavigation of the globe, followed by the development of the sciences generally, prepared the way for this new science. * * * * *
